Abstract:
Wireless networks and particularly ad hoc networks, are gaining in speed and capacity. These advances open the way to their use in emergent, increasingly complex applications. Such networks have to operate in disturbed environments where disturbances, mainly caused by fading and interferences, primarily originate by the physical layer. Congestions associated with environment-specific disturbances caused by complex applications, such as emergency and disaster applications, are the second source of disturbance. Such networks must guarantee a QoS (Quality of Service) management to their associated applications, a task that is possible only by minimizing the transmission delay and maximizing the packets delivery ratio. The conventional network architecture used for TCP/IP model shows degradations of performance, especially when the networks operate in environments with physical layer disturbances. This paper presents a study based on the routing performance of ad hoc networks operating in disturbed environment. Simulation results are presented and analyzed to illustrate limitations of the conventional ad hoc network architecture. The methodology of a network architectural design based on cross-layer architecture using a multi-criteria decision making process for quality enhancement is also presented. This work enabled us to highlight a new direction for the communication architecture of cognitive vehicular networks operating under disturbed environment. This direction consists of considering a dynamic reconfiguration of the communication architecture according to the network environment behaviour. Thus, it will allow either the traditional architecture or the cross layer architecture based on autonomous components.
