Performance of Mobility for Wireless Mesh Networks
Wireless Mesh Networks (WMNs) with the objective to reduce the network traffic incurred by mobility management and packet delivery is proposed. These schemes are per-user based, i.e., the optimal threshold of the forwarding chain length that minimizes the overall network traffic is dynamically determined for each individual mobile user, based on the user's specific mobility and service patterns. Analytical models based on stochastic Petri nets are developed to evaluate the performance of the proposed schemes. The authors demonstrate that there exists an optimal threshold of the forwarding chain length, given a set of parameters characterizing the specific mobility and service patterns of a mobile user.
