The Y-Comm security group believes that a new security approach is needed to address the security challenges in 4G networks. This paper sheds light on our approach of providing security for the Y-Comm architecture as an example of 4G communication frameworks. Our approach proposes a four-layer security integrated module to protect data and three targeted security models to protect different network entities, thus providing security in different situations without affecting the dynamics of the 4G networks.

As pressures mount on healthcare systems to provide treatment to patients, mHealth is seen as one of the possible solutions to addressing these challenges. Given the sensitivity of health data, the rapid development of the mHealth sector raises privacy concerns. The aims of this research were to investigate privacy threats/concerns in the context of mHealth and the management of chronic diseases and to propose a novel privacy framework to address these concerns. Subject and method The study adopted a modified version of the engineering design process. After defining the problem, information was gathered through literature reviews, and analyses of existing regulatory (privacy) frameworks and past research on privacy threats/concerns. Requirements for a new framework were then specified leading to its development and comparison with existing frameworks. Results A novel future-proof privacy framework was developed and illustrated. Using existing regulatory frameworks for privacy and privacy threats/concerns from research studies, privacy principles and their resulting requirements were identified. Furthermore, mechanisms and associated technologies needed to implement the privacy principles/requirements into a functional prototype were also identified. A comparison of the proposed framework with existing frameworks, showed that it addressed privacy threats/concerns in a more comprehensive manner. Conclusion This research makes a valuable contribution to protecting privacy in mHealth. The novel framework developed is an improvement on existing frameworks. It is also future-proof since its foundations are built on regulatory frameworks and privacy threats/concerns existing at the time of its deployment/revision.

When an object (e.g. a notebook computer) connects, a handshaking protocol assigns functions such as data or power transmission to the various conducting paths that are established. This paper describes the position occupied by this concept in the world of networking, presents an overview of the technology used in its realisation, describes the current prototype implementation, and outlines the potential implications of its introduction.

The Intelligent Transport System (ITS) is a part of the smart cities which provides intelligence placed near the roadside or it can be developed in the vehicle. Static traffic light signal is a predefined and cannot change in Peak Hours as well as Non-Peak Hours. In dynamic traffic light signal all the signal are changed with reference to signal phase and according to predefined times during different times in day, which will change the signal timing to RED and GREEN in both peak and non-peak hours. In future there will be fully dynamic traffic light in which all the signal will change when any emergency vehicle as well as where there is que of traffic it will give way to the que of traffic. In real time this can be achieved through communication between vehicles and traffic infrastructure. I will be using Green Light Optimal Speed Advisory (GLOSA) system as well as Signal Phase and Timing (SPAT) and probabilistic approach as part of the methodology with the help of Vehicular ad-hoc Network (VANET). There will be some probabilistic approach in the research to get the appropriate timing for each of the vehicle. For this we will use VANET test-bed, Programmable Logic Controller (PLC) as well as HMI for displaying messages on the driver screen. The future work in this research will be that all the traffic signal will be controlled by the PLC and if there is any emergency vehicle or traffic queuing then they will get the first priority

A Cooperative Intelligent Transport System (C-ITS) is a fusion of transport and communication facilities, which allows vehicles to communicate with each other and with the transport infrastructure. This paper discusses how traffic prediction can be incorporated and how congestion can be reduced by using C-ITS. Probability and mathematical modelling based on total traffic flow and average speed for weekdays and weekends have been used in this work which shows that traffic congestion can be minimised near junctions. Datasets provided by the Highway England have been used in this study. The datasets provide different measurement categories such as Total Traffic Flow, Traffic Flow for vehicles less than 5.2 m, Total Traffic Flow vehicles between 5.21m-6.0m, Total Traffic Flow above 6.6m and Average Speed. From these different categories, this paper uses Total Traffic Flow for calculating Average Mean and Standard Deviation parameters. The generated traffic mathematical model is used to predict traffic and this has been compared with the actual traffic near the junction. In addition, at the junction, Emergency vehicles will also be prioritised. This will be done with the help of Programmable Logic controller (PLC) and Human Machine Interface (HMI). The traffic prediction is being looked at with the help of probabilistic modelling implemented in the MATLAB

The trial network is intended to serve as a testbed for research into new paradigms for wireless communications, and will provide an infrastructure for research on home networks. After a brief discussion of the network provisioning methods required to make the network operational, we present some preliminary measurement results. We then identify potential performance issues and propose some possible solutions as future work.

A shortcoming of such environments is their lack of support for continuous flows of information. What is missing is the notion of an ongoing communication activity with an associated quality of service. This paper describes a model for integrating multimedia flows into a distributed computing system. The model permits explicit bindings to be established between type-checked stream interfaces. The stream binding is represented in the computational model as a first-class object which encapsulates configuration rules and QoS attributes. An operational interface supplied by the binding object allows other objects within the system to manage the binding, to renegotiate QoS parameters, to control the flows across the binding, and to register interest in stream events such as flow reports and communication errors. The in-band stream interface is an abstract C++ wrapper around transport mechanisms that include intra-host IPC and network transport protocols such as TCP and XTP. A prototype implementation of this model is described using the Common Object Request Broker Architecture (CORBA). The implementation environment comprises a local area ATM network with directly attached multimedia peripherals and general purpose workstations.

To this extent, this paper investigates the experimental performance of Snort-based NIDS (S-NIDS) in a practical network with the latest technology in various network scenarios including high data speed and/or heavy traffic and/or large packet size. An effective testbed is designed based on Snort using different muti-core processors, e.g., i5 and i7, with different operating systems, e.g., Windows 7, Windows Server and Linux. Furthermore, considering an enterprise network consisting of multiple virtual local area networks (VLANs), a centralised parallel S-NIDS (CPS-NIDS) is proposed with the support of a centralised database server to deal with high data speed and heavy traffic. Experimental evaluation is carried out for each network configuration to evaluate the performance of the S-NIDS in different network scenarios as well as validating the effectiveness of the proposed CPS-NIDS. In particular, by analysing packet analysis efficiency, an improved performance of up to 10% is shown to be achieved with Linux over other operating systems, while up to 8% of improved performance can be achieved with i7 over i5 processors.

However, the current proposed protocol specification does not support a suitable handoff mechanism to allow a mobile computer to change its point of attachment from one network to another. This paper describes a handoff mechanism for a mobile host which makes use of Internet Protocol version 6 (IPv6) and Mobile IP without the need to introduce a new mobility management protocol or make changes to the network infrastructure.

The demand for passenger transportation, especially by road, has been increasing due to the globalization process, resulting in delays and traffic congestion. However with the deployment of modern technology such as Satellite Navigation systems and modern vehicular networks, it is possible to know the exact state of vehicles including their sources and destinations of travel. This allows us to explore new traffic analysis based on the journeys of vehicles within the system to reduce traffic delays and congestion. This paper aims to address these challenges in particular, the congestion at road junctions, using a Zero Server Markov chain technique, which is an analytical model that has been developed to obtain average delays and average numbers of vehicles at a junction. In normal traffic analysis, Dijkstra’s algorithm is used but the time at the junction is usually estimated. Our new approach, using Queueing Theory, allows a more detailed analysis of delays at junction and hence more accurate end-to-end journey times. In addition, using a probabilistic approach based on cars turning left, going straight, or turning right at a junction obtained from traffic data available from Highways England, it is possible to acquire accurate input/output flows of traffic at the junction. Secondly, this paper will incorporate these findings into the analysis of journey times using the OSHI (Operating System and Hardware Information) Platform. Finally, these new techniques and results will then be used to minimise the journey times on the MIDDLESEX University VANET Testbed which is a real-time vehicular network in London (UK)

It depends on Power Utilization, Code Utilization, Iub (interface between the Radio Network Controller (RNC) and the Node B) and Channel Element (CE). The location of Node B plays a crucial role in 3G Planning. The Radio Frequency planner needs to select the best optimal location for setting up the 3G site in order to a seamless coverage to the customers. In this paper, these topics are explored in a detail manner. For this planning the Node B layout for Airtel in the densely populated Santhome area of Chennai is discussed. The basis issue is the interdependence between coverage and capacity in 3G. In 3G systems, both capacity and quality should be monitored to ensure the best network performance. Planning of new base station has been first treated with an analytical study of the cell coverage range for a specific environment and service. The accomplished results have been checked using ASSET simulation tool and Geographical Information System (GIS) tool.
