Cost-effective maximum lifetime routing protocol for wireless sensor networks

Wireless sensor networks are composed of a high number of very simple nodes where most of them have to perform the function of a router. Energy consumption of these nodes is important as power is supplied to the nodes by limited batteries, which circumscribe the lifetime of the links as well as the whole network. Some of the recent routing protocols are greedy on network lifetime by balancing the remaining energies among the nodes in the networks. Although, these algorithms help to maintain the stability of the network, they are not as cost effective as existing traditional routing algorithms. Our proposed method makes a tradeoff between the routing cost and network lifetime issues in route selection, and ensures a good compromise between these two conflicting interests.
