MISR: Multiple Inheritor Selection for Recovery of Nodes in Faulty Cluster in Wireless Sensor Networks


Sanam Hosseini and Elmira Moghaddami Khalilzad

A wireless sensor network composed of many sensor nodes which are used to monitor unavailable and harsh environments. Because these nodes are too small and battery operated which have limited energy, faults may occur. Fault tolerance is one of the most important issues in wireless sensor networks and must be increased as much as possible to avoid faults. In wireless sensor networks which use clustering architecture, the role of cluster head is very important and critical and fault tolerance in cluster head must be increased. Different approaches for increasing fault tolerance and fault management presented that have advantages and disadvantages. An approach for fault management in cluster head is to recover members of faulty cluster with specifying new cluster head for them. In this paper a new recovery algorithm based on inheritor selection is proposed. Previous algorithms do cluster head selection when each fault occurs but the proposed algorithm does this selection once and can select cluster head rapidly and without too much calculation. Simulations results show that the proposed algorithm has better performance in contrast to previous algorithms.
