These CHs gather data from their local clusters aggregate them & send them to the base station. On the LEACH many new schemes have been proposed to enhance its activity like its efficiency, security etc. In this paper the fault tolerance issue is being incorporated. | ISSN:2249-5789 Rudranath Mitra et al, International Journal of Computer Science & Communication Networks,Vol 2(3), 380-384 Incorporating Fault Tolerance in LEACH Protocol for Wireless Sensor Networks Rudranath Mitra1 , Anurupa Biswas2 Department of Information Technology Heritage Institute of Technology Anandapur,. Abstract Routing protocols have been a challenging issue in wireless sensor networks. WSN is one of the focussed are of research because of its multiaspect applications. These networks are selforganized using clustering algorithms to conserve energy. LEACH (Low-Energy Adaptive Clustering Hierarchy) protocol[1] is one of the significant protocols for routing in WSN. In LEACH, sensor nodes are organized in several small clusters where there are cluster heads in each cluster. These CHs gather data from their local clusters aggregate them & send them to the base station. On the LEACH many new schemes have been proposed to enhance its activity like its efficiency, security etc. In this paper the fault tolerance issue is being incorporated. Key words: Cluster-head, CH, BS, LEACH, fault tolerance. heads must be an autonomous, distributed process. This is achieved through LEACH. 1. Introduction A clustered architecture organizes the sensor nodes into clusters, where each cluster is governed by a cluster-head. The nodes in each cluster are involved in message exchanges with their respective clusterheads & these CHs send messages to their respective BSs, which is usually an access point connected to a wired network. Fig. 1 represents a clustered architecture where any message can reach the BS by at most 2 hops. Clustering can be extended to greater depths hierarchically. Clustered architecture is specially useful for sensor networks because of its capability for data fusion. The data gathered together by all members of the cluster at the cluster-head and only the resulting information are sent to the BS. .
