Abstract

In this paper, we have examined the problem of simultaneous failure of sensors within the wireless sensor networks (WSN), whereby the sensors failures are due to malfunction or electrical faults. We have proposed a mobility assisted coverage restoration algorithm, which restores the coverage of the failed sensors without adding new sensors. The proposed algorithm follows two phases; clustering and restoration. The clustering phase groups the failed sensors with their proximity, and then it relocates them into cluster. The restoration phase moves the nearby active sensor with higher energy to the center of the cluster of failed sensors and doubles its sensing area to restore the coverage. The restoration scheme exploits the mobility of the sensors to form clusters of failed sensor, which reduce the number of restoring sensors, thereby prolonging the lifespan of the network. Experimental results indicate that for a small size WSN comprising of 25 nodes and nine nodes of it failing simultaneously, our restoration algorithm is able to increase the coverage area from 34% to 86% at the expense of small reduction in the lifespan estimated to be 24% of the network.
