Abstract:
One of the most important factors in using wireless networks is to enable the nodes to move. Thus, it is crucial to a wireless network designer or analyst to investigate the effect of mobility of the nodes on the performance of mobile wireless networks. This problem is considered here in a systematic approach. The general approach proposed is the intermediate performance modeling. After introducing the theoretical framework, link statistics is used as intermediate performance measures and the rest of the work is conducted in two lines. We first show that such measures can be obtained analytically or by experiments and then use them to obtain analytical results about different protocols. For the first part, link statistics for several simple mobility models is investigated analytically and the effect of some factors, such as buffer zone and stationary nodes, is studied. For the second part, the effect of mobility on the homogenous topology, performance of KNeigh topology control protocol, performace of LEACH protocol, performance of beaconing, performance of some delay-tolerant networks, and self-similar behaivior of the traffic is studied.
