To Extend the Lifetime of Cluster Head Node by Applying SEP Protocol
A Mobile Ad hoc NETwork (MANET) is a temporary network formed by a number of mobile nodes without a centralized administration or wired infrastructure. The dynamic nature of these ad hoc networks makes support of QoS (Quality of Service) a challenging and difficult task where nodes may leave and join the network or move around anytime. In this paper, the authors present a Stable Election Protocol (SEP) for extending the lifetime of cluster head node. In mobile ad hoc networks, the movement of the network nodes may quickly change the topology resulting in the increase of the overhead message in topology maintenance and changing of the cluster head node.
