Multihop Energy Efficient Reliable and Fault Tolerant Routing Protocol for Wireless Sensor Networks

-The work in this paper aims at designing a multihop energy efficient, reliable and fault tolerant routing protocol. It proposes to maintain an asymmetric network of sensors so that the nodes get a chance to configure their transmission ranges best, and thus delivers data to the base station using as little energy as possible. Our protocol design concentrates on the load sharing feature by maintaining multiple routes and selecting the best one for relaying the data packets. It assigns different transmission powers to different nodes based on the network topology. The problem of bottleneck around the base station is addressed by varying the transmission ranges of the nodes periodically, which changes the topology, to balance the responsibility among the nodes across the network.
