Beyond the WiFi: Introducing RFID system
using IPv6
Labonnah F Rahman, Mamun B.I Reaz, Mohd
Alauddin Mohd Ali, Mohammad Marufuzzaman,
Muhammad Raisul Alam (Universiti
Kebangsaan Malaysia, Malaysia)
RFID System suffers from limited address
space and local mobility. Moreover, it
is a monopoly business with few vendors,
which are trying to dominate the market
with proprietary standard of RFID
reader. The proposed system will replace
the expensive RFID reader with cheap
Wireless Network Interface Card (WNIC).
For the purpose, an innovative scheme
for RFID tagging system is introduced
which will be benefited by well-defined
WiFi protocol. IPv6 (Internet Protocol
version 6) address will be used as
product identifier. This will provide a
universal identity of the objects with
seamless global mobility. The EPC
(Electronic Product Code) will directly
map to IPv6 address by using an auto
configuration method. So that 64 bit EPC
will take the place of the EUI-64
portion of IPv6 address. The proposed
system suggests the mechanism of
reducing significant cost, physical
location detection and usage of global
unique address, which will also be
compatible with existing EPC addressing
scheme. |

Diversity transmission systems
Daniele Trinchero, Alessandro Galardini, Riccardo Stefanelli (Politecnico
di Torino, Italy)
The paper analyses the performance of
wireless networks working over
unlicensed frequency ranges, making use
of diversity transmission systems, as an
effective means to increase outdoor
coverage capabilities in rural
scenarios. To this purpose, a network
has been designed and realized,
providing coverage to a wide rural area
in the hills of Piedmont, a region
located in North-Western Italy. Once
constructed, the network performance has
been monitored and characterized, in
terms of coverage capabilities, signal
quality, and noise immunity. |

SIP Trunking the route to the new VoIP
services
Ivan Gaboli, Virgilio Puglia (Italtel
S.p.A., Italy)
This work gives an overview of SIP
Trunking solution and explains the
existing difficulties in implementing
VoIP services, when this architecture is
deployed in multivendor environment. The
causes of these problems are explained
with two existing approaches used by
carrier to solve interoperability: they
are Full Jacket SIP-Trunk and Customized
SIP Trunk. A solution to cover the
lackings of SIP standards is the
introduction of a SIP adaptation device
called "Inter-Domain Adaptation Device"
which will increase the potentiality of
SIP-Trunking based solutions. It is also
proposed a method for assessing the
complexity of different approaches to
SIP-Trunking applications. |

Global e-Public Service (GePS)
Priyantha K Weerabahu (DMS Electronics
Ltd., Sri Lanka)
This paper proposes a Global e-Public Service (GePS) to electronically deliver public services in a more efficient way by maximizing the utilization of resources and providing all countries a common platform to help its citizens and reduce the inequity in the world. Most of primary services which all governments need to provide to its citizens could be delivered electronically through e-government initiatives. These e-services were identified through research of leading e-government portals and a reference model for an e-government portal was developed. Resources required by each government to provide services common to all are a wasteful exercise. The Global e-Public Service defines a mechanism to develop these electronic public services centrally by a global agency and to implement them by various governments as integrated and decentralized systems around the world.

Integrating Wireless Sensor Networks and
Mobile Ad hoc Networks for an Enhanced
End-user Experience
Saba Hamedi, Mohammadmajid Hormati, Roch
Glitho, Ferhat Khendek (Concordia
University, Canada)
Wireless sensor networks (WSNs) sense
and aggregate ambient information (e.g.
space, environment or physiological
data). Ambient information can enhance
end-user experience and is made
available to end-user applications
(which may reside in another network)
via gateways. Gateways are usually
centralized and fixed. Mobile ad hoc
networks (MANETs) are networks that can
be deployed "on the fly". They are
useful in situations such as emergency
response operations. When the ambient
information collected by WSNs is
intended for applications residing in a
MANET, centralized and fixed gateways
are not practicably feasible. This paper
proposes an overall two-level overlay
architecture to integrate WSNs (with
mobile and distributed gateways) and
MANETs, for an enhanced end-user
experience. It also proposes a new
architecture to interconnect the two
overlays of the overall architecture.
Motivating scenarios are presented,
requirements are derived, and the
two-level overlay is discussed along
with the proposed interconnection
architecture. The prototype is also
presented. |

Telecommunications Business Model For
Converged Networks Focusing Final Users
Cledson Sakurai, Moacyr Martucci Junior, Andr� Hiyuiti Hirakawa (University of Sao
Paulo, Brazil)
The telecommunications converged
networks, specially inside of new
Internet environment, makes possible
supply a plenty of services to users, as
voice and multimedia services with
assured perceived quality of services (QoS)
through different access technologies,
however this brings a complex scenario
in terms of technology in order to fit
the user perceived QoS needs to
appropriate technical QoS requirements,
and also delivery the right service to a
particular user. Therefore, to enable
the appropriate service delivery for
each user, this article proposes a
business model for the
telecommunications segment, aiming
delivery services according to
particular User Service Level Agreements
(USLAs), prepared transparently of the
technologies involved, and using QoS
parameters according to the users
literacy. The proposed business model
considers four providers: Services,
Infrastructure, Content and Access
aiming to facilitate the relationship
between users and providers, and to
clarify the roles and responsibilities
of each actor, as well. This paper
presents the proposed business model,
and discuss the needs for an regulatory
frameworks necessary to meet the
requirements of proposed business model
with focus on users. |

On Demand Fine Grain Resource Monitoring
System for Server Consolidation
Arnupharp Viratanapanu, Ahmad Kamil
Abdul Hamid, Yoshihiro Kawahara, Tohru
Asami (The University of Tokyo, Japan)
Server consolidation and virtualization
technology are used in modern data
center as a method to improve the server
utilization rate by encouraging the
sharing of physical re- sources between
virtual machines (VM). Although, this
can be realized by plenty of
virtualization softwares available in
markets, creating a good management
policy for the server consolidation
environment is still a challenging
research problem. The policy should be
able to maintain the high re- source
sharing rate, while keeping the
performance drop rate as low as
possible, which are totally contradict
requirements. In order to progress the
research in this area, a monitoring
system, which can effectively monitor
current system state and collect
essential information, is indispensable.
However, due to many differences in use
case scenarios, monitoring systems
designed for conventional management
domain can- not be applied directly.
This needs us to reconsider the design
of the monitoring system. This paper
proposes some key information that is
still missing from existing monitoring
systems as well as the design of Pantau,
a monitoring sys- tem designed for
capturing information necessary for
server consolidation. |

Describing and Selecting Communication
Services in a Service Oriented Network
Architecture
Rahamatullah Khondoker, Bernd Reuther,
Dennis Schwerdel, Abbas Siddiqui, Paul
Mueller (University of Kaiserslautern,
Germany)
Today networks offer communication
services ranging from a rather simple
and unsecure one to secure and reliable
data transmission for communicating on
the network. In the future, it is
expected that networks will offer a
large number of different communication
services. With so many services
available, determining which service to
select and use becomes much more
difficult. Here we propose a description
schema including an ontology for
describing communication services. For
service selection a decision making
process called Analytic Hierarchy
Process (AHP) is utilized which is
specially adapted and extended for
automatic processing. |

Adaptive Resource Allocation for
Real-Time Services in OFDMA Based
Cognitive Radio Systems
Dhananjay Kumar, Shanmugam Mahalaxmi,
Jayakumar Sharad Kumar, Rangarajan Ramya
(Anna University Chennai, India)
In this paper an adaptive resource
allocation algorithm in OFDMA based
cognitive radio (CR) system is proposed
that not only meets the quality of
service (QoS) of real-time (RT) services
but also increases the dynamic capacity
of the system. In contrast to existing
algorithms for multi-user OFDM systems
which are unable to guarantee maximum
sum data rate when applied to CR system
in real-time, the proposed joint sub
carrier and power allocation algorithm
(JSPA) ensures maximum sum data rate
under power constraint while improving
the system capacity. We model the
resource allocation problem with the
goal of maximizing the overall system
throughput. By judicially assigning
resource in primary and secondary
sources based on the types of
application JSPA demonstrates that the
system efficiency and throughput can be
dynamically enhanced. JSPA is simulated
under two types of services: constant
bit rate (CBR) and variable bit rate
(VBR). |

All Photonic Analogue to Digital and
Digital to analogue conversion
techniques for digital RADIO over FIBRE
SYSTEM applications
Seyed Reza Abdollahi1, Hamed Saffa
Al-Raweshidy1, Rajagopal Nilavalan1;
Sied Mehdi Fakhraie2 (1Brunel
University, United Kingdom; 2University
of Tehran, Iran)
Wideband electronic analogue to digital
conversion (ADC) systems have critical
problems encountered in high-frequency
broadband communication systems that the
recent electronic ADCs (EADC) have
experienced those such as uncertainty of
sampling time. In this paper, an all
photonic sampling and quantization ADC
and photonic digital to analogue
conversion system with six effective
number of bits (ENOB) is designed. By
using this photonic ADC (PADC), a novel
digital radio over fibre link for
wireless radio frequency (RF) signal
transportation over 20 Km single mode
fibre has been designed whose
performance is investigated in this
paper. In the digital radio over fibre,
the dynamic range is independent of the
fibre length. |

Enhancing CyberSecurity for Future
Networks
Raj Puri1; Anthony Rutkowski2 (1Yaana
Technologies, USA; 2Georgia Institute of
Technology, USA)
Next Generation Networks, including
specialized implementations such as
Cloud Computing and Smart Grids, must be
significantly more robust than today's
networks - with "baked in" capabilities
supporting an array of assurance and
cybersecurity capabilities. One of the
most significant emerging means of
achieving these capabilities is by
applying an ensemble of new
specifications being developed under the
aegis of ITU-T Study Group 17 known as
CYBEX - the Cybersecurity Information
Exchange Framework. This paper describes
the CYBEX Framework, how it came into
existence, and its potential application
to Future Networks. |

Towards a Service-Oriented Network
Virtualization Architecture
May El Barachi1; Nadjia Kara2; Rachida
Dssouli3 (1Concordia University, Canada;
2�cole de Technologie Sup�rieure,
Canada; 3UAEU, UAE)
Network virtualization is an emerging
concept that enables the creation of
several co-existing logical network
instances (or virtual networks) over a
shared physical network infrastructure.
There are several motivations behind
this concept, including: cost-effective
sharing of resources; customizable
networking solutions; and the
convergence of existing network
infrastructures. In this paper, we
analyze the existing (conventional and
virtualized) business models and propose
a new business model for virtual
networking environments. Our proposed
model is a service-oriented hierarchical
model, in which different levels of
services (i.e. essential services,
service enablers, service building
blocks, and end-user services) offered
by various players, can be dynamically
discovered, used, and composed. Using
this business model as basis, we also
define a layered service-oriented
network virtualization architecture and
discuss some of the issues related to
its operation. |

Thin Apps Store for Smart Phones Based
on Private Cloud Infrastructure
Ashish Tanwer, Abhishek Tayal, Muzahid Hussain, Parminder Reel (Thapar
University, India)
A novel approach to implement cloud
computing for smart phone devices has
been presented based on Eucalyptus, an
open source cloud-computing framework
that provides infrastructure as a
service (IaaS). It has full support of
Virtualization and is Amazon Web
Services interface compatible. A private
cloud has been designed using Eucalyptus
to develop a smart phone application
store. The architecture, physical and
network implementation of Eucalyptus
Private Cloud on Intel based platform
has been discussed in details. We have
developed two sample thin applications
for mobile based on mobile learning that
can be downloaded from our private cloud
using Amazon Web Services Platform (PaaS).
These thin apps use the private cloud as
computing platform, and perform better
even on low processing smart phones. |
