Wireless Sensor Network energy efficiency is the important factor of the network lifetime, most of the sensor nodes are present in an isolated urban fields to sensing the data in particular area .These sensor nodes are working in typical condition. In this paper, the authors address the problems of cluster node failure. When a cluster node fails because of energy depletion they need to choose alternative cluster for that particular region. In periodical time each sensor node in the cluster should possess the next cluster head re-election based on energy to avoid node failure.
