Real-world investigation of mobility models in an anycast wireless ad hoc network

摘要

Present study attempts to offer approved investigation of locating the nearest server to a group of content-equivalent ones in a wireless ad hoc network. Different mobility models are used to measure the performance of wireless ad hoc networks with an anycast mechanism in an outdoor environment. Anycasting is defined as a useful communication sample for ad hoc networks in which resource adequacy and robustness is significantly important. All the network configurations are done by laptop computers with windows vista operating system. A multithread program which is based on an application layer anycast one is applied to evaluate the network functionality. The operation of five main performance criteria - response ratio, duplicate ratio, average number of hops, average response time and relative network traffic were studied in which different models were applied.
