An investigation of the impact of mobility on the protocol performance in wireless sensor networks

Mobility has introduced a new dimension to the wireless research areas such as IP mobility management protocols and wireless ad hoc networks. In this paper we take a closer look at the issues related to the mobility in wireless sensor networks (WSNs). The aim of this work is to identify improvements that can be obtained considering mobility, recognize its research challenges. We describe different levels of mobility in WSNs and highlight the effect of the mobility on the performance of WSN protocols.
