Abstract:
A wireless sensor network (WSN) is a form of network that consists of randomly distributed devices/nodes ina known space. In this kind of environment there are two major concerns that governs the efficiency, availability andfunctionality of the network, namely power consumption and fault tolerance. This paper introduces a new algorithm thatis Power Efficient Cluster Algorithm  (PECA). The main focus of the proposed algorithm is to reduce the power consumptionrequired to setup the network since it is the stage where power is used the most. This is achieved by reducing the totalnumber of radio transmission required for the network setup.  As a fault tolerance approach, the algorithm stores someinformation about each node for easier recovery of the network should any node fails in the network. The proposedalgorithm is compared with Self Organizing Sensor (SOS) algorithm; the result shows that PECA consume significantlyless power than SOS.
