Executive Summary

Wireless Sensor Networks (WSNs) has a wide variety of applications such as Healthcare, home security, biological detection and battlefield surveillance. It has brought new challenges to the researcher of network protocols. One fundamental problem in wireless sensor networks is the connectivity issue, which reflects how best a network is connected or linked to each other by sensors and also needs to be ensured so that the sink sensor node receives all sensed data for further processing. It is very important to have full connectivity in a WSN, after it is deployed and also to maintain the same.
