Abstract 

 

Sensor nodes forming wireless sensor networks (WSNs), are generally equipped with a low computing capacity, a small antenna and a very limited energy source; which makes the batteries critical resources from where their use must be efficient. On the other hand, The used communication protocol to deliver data from source to destination in a WSN is the biggest energy consumer. Indeed, in a dense WSN, each node may route messages to a destination node either through short-hops or long- hops, by using long or short radio range. Thus, the hop lengths optimization can save energy. In this paper, we propose an multi- path routing algorithm based on the ideal hop’s range to improve WSN power consumption. The simulation results obtained by applying the proposed algorithm on several WSNs reveal a high performance regarding WSNs energy consumption and networks lifetime.
