Wireless sensor network extremely popular for monitoring the secluded or unfriendly environments. The duration of the network is the major problem in wireless sensor network. The duration of the wireless sensor is the time in which it covers all the targets. This problem can be solved by observing the less number of the nodule lively at the particular time. The sensors from the active sets are monitoring all targets and liable to transmit the data to the base station and remaining nodes are in sleep mode. In this paper, the authors discussed about two algorithms one is SVM (Support Vector Machine) and another is genetic algorithm used in wireless sensor network. The SVM is used to detect the fault tolerance and genetic algorithm is used to find the optimal path.
