Group mobility based clustering scheme for mobile wireless sensor networks

Nowadays, mobile wireless sensor networks have many applications especially in a group movement such as evacuation system, search and rescue activity. To support the group movement and to achieve an energy-efficient protocol, we propose a Group mobility based Clustering (GC) scheme. This protocol reduces the control overhead in the setup phase of a clustering system by introducing a concept of group leader and group member. In this scheme, the communication with cluster-head is only done by the group leader to save the energy consumption. Based on the simulation results, GC Single increases the lifetime of the networks and the number of packets received at a base station, compared with LEACH, MN-LEACH.
