Performance study of routing protocols based on node mobility in MANETs

Mobile ad hoc network (MANET) is established by a set of smart mobile nodes without any central intelligence. Hence, nodes auto-discover their surrounding and establish needed links between source and destination node. Moreover, mobile nodes change arbitrary their position, which lead to frequent link failure. Therefore, the dynamic behaviour of nodes has a drastic impact on network's performances such as end-to-end delay, packet loss ratio and traffic control that is generated during route update process. Consequently, the main issue in MANET's operations is the design of an efficient routing protocol able to deliver required quality of service in case of nodes' mobility and manage the intrinsic limitation of wireless networks, like scares bandwidth, limited energy and processing capabilities. The purpose of this paper is to study the impact of nodes' mobility on routing performances and look forward an appropriate optimisation that might enhance efficiency of routing protocol in high dynamic environment.
