It is the era of Wireless Sensor Network. .Looking at rapidly increasing growth of Smartphones , soon there will be larger number of Smartphones than number of people in the world as each and every person will be having more than one Smartphones. Soon the biggest Wireless Sensor Network will be the network of Smartphones. "No doubt!" The biggest sensor network existing today is having linear topology. In sensor network as soon as one sensor node dies it can result in "the end of connectivity of whole wireless sensor network and the sensor network will be of no use, and we have to redeploy whole sensor network again, might be other nodes are functioning well, they are left as such. Therefore enhancing connectivity for longer time among sensor nodes is the only option left to save us from redeploying nodes from scratch.
