A Flooding Mechanism of Stateless Anycast Routing in Mobile Wireless Ad Hoc Networks

Abstract

A detailed simulation study, together with real-world experiments, a stateless flooding mechanism for anycast routing in a mobile wireless ad hoc network is studied with a developed model. The model covers reli-ability aspects of wireless communication in such networks with a rout-ing mechanism using a scheme of orientation-dependent inter-node communication links. Using the mechanism, the paper addresses another issue of locating the nearest server from a group of replicated servers in the network. A class of extended Petri nets is used in the development of the simulation model to explicitly represent parallelism of events and processes in the network. An application layer prototype system is implemented based on the proposed routing model without any changes at lower layers of the network protocol stack. In simulation and real -world experiments, the behavior of five fundamental performance met-rics - response ratio, relative traffic, average response time, average number of hops, and duplicate ratio - were investigated by changing distance of transmission, motion pattern and combining with different model parameters.
