LIBRO: A Location Information Based Routing Protocol for Multi-Hop WSN Applications

In Wireless Sensor Networks (WSN), the nodes may be randomly deployed over a harsh geographical zone. Usually, these nodes are battery powered with limited transmission and processing capabilities. Managing the residual energy is very crucial in such network, since replacing a battery may not be always feasible. Energy is essentially consumed during packet transmission phase. Therefore, routing protocols become of a high importance since they impact on energy consumption during data transmissions. In this paper, we present a new routing protocol based on the geographical location information in an uplink multi-hop WSN. The proposed protocol assumes that the geographical zone and the transmitted data are more precious than the sender node authentication. Our proposed protocol guarantees the delivery of data packet in a dense network without any knowledge of the topology nor the path nodes between the source and the destination. We analytically derive the average consumed energy, the probability of packet loss, and the mean delivery time. Numerical results corroborate the superiority of our protocol over the state-of-the-art Distance Routing Protocol (DIR) in terms of connectivity, lifespan, memory, and latency.
