SSMCA: CA based Segmented Sensor Network Management scheme

The wireless sensor network (WSN) encounters resource restrictions such as low computational power, reduced bandwidth & limited power resource and it demands efficient management of such resources. This work proposes a scheme (SSMCA), developed around the cellular automata (CA), for efficient management of battery power in sensor nodes with optimized cost of implementation. Each sensor node is assumed to be equipped with a segment of the CA, selected for the network that defines the state (active/standby) of the node at next time instant. The CA based management of status (active/standby) of a node ensures the reduced battery power consumption in nodes of a cluster as well as in the whole sensor network. As a segment of the CA is planted within a node, the additional cost for implementation of the proposed scheme is marginal. The simulation results establish that the SSMCA can better utilize the resources and ensure a maximally covered energy efficient sensor network.
