Abstract
Efficient power utilization gains more importance for WSNs (Wireless sensor Network), since battery replacement is not possible in many sensor applications. Sensors consume energy when it changes from one radio state (transmission, reception, listen, sleep) to another. In this paper, a Cluster-based Power-Aware Scheduling (CPAS) algorithm is proposed to specifically design a low-data-rate WSNs to reduce the number of state transitions of a node, thereby efficiently maintaining the power level of the network. In CPAS, the nodes within the cluster are first synchronized to avoid collision during transmission. CPAS is based on IEEE 802.15.4 standard with dynamic routing ability based on the power level of the nodes. Performance evaluation is done by using simulation, and it has been showed that this cluster based algorithm considerably improves network lifetime when compared to non-cluster based network in WSN.
