In Wireless Sensor Network, dynamic cluster based routing protocol approach is mostly used. In this approach, most frequently cluster reelection algorithm is performed due to the energy depletion of cluster heads. This repeated cluster head reelection increases the number of advertisement messages which in turn depletes the energy of overall sensor network. Here, the authors proposed a novel Supervisory Selection Time Approach (SSTA) that reduces the cluster set up communication overhead in backup node determination Phase.
