PERFORMANCE ANALYSIS AND ISSUES OF MOBILE SENSOR NETWORK
Divya Bharti, Manjeet Behniwal, Ajay Kumar Singh · 2013
Wireless sensor networks are expected to be one of the key enabling technologies in the next 10 years. Protocols for such networks should be highly flexible in order to adapt to topology changes due to node mobility. Dynamic changes in the cluster structure leads to performance degradation of the network. Nodes in WSNs are generally assumed to be static. However, many recent applications make use of mobile sensor nodes. This poses some unique challenges to WSN researchers. Depending on their roles in WSNs (sinks, routers, or sensors), nodes may move individually or in groups with respect to some reference system. This mobility changes network topology. Topology changes occur in a dynamic WSN when nodes disconnect or connect from/to all or some of their neighbours, whether forced by changing of locations of nodes or adding/removing nodes. In this paper, we will explore the impact of mobility over wireless sensor network and various solutions offered by the
