A Protocol for Improving the Reliability of Wireless Sensor Networks

Wireless sensor networks suffer from some setbacks due to its ad-hoc nature of deployment and its node are prone to be defective due to several conditions like weather, environment where sensors are deployed etc. It also suffers from resource limitations, high failure rates and faults caused by the defective nature of wireless communication and the wireless sensor characteristics. This can lead to situations, where nodes are often interrupted during data transmission and blind spots occur in the network by isolating some of the devices. Hence reliability and availability is an important research area necessary to make wireless sensor networks more acceptable as a means of communication. In this paper, the issue of reliability will be addressed by designing and developing an improved fault-tolerance mechanism of Ad-hoc On-Deman
