Abstract

Energy efficiency is one of the most important factors in the design of wireless sensor networks. Due to the broadcast nature of sensor networks, every node in the vicinity of the sender may overhear the transmitted messages even if it is not an intended recipient. Overhearing transmissions results in unnecessary expenditure of energy. In this work, we investigate the energy-efficient multicast routing problem for sensor networks. We propose a fully distributed protocol that takes into consideration the impact of overhearing transmissions on energy expenditure. To the best of our knowledge, this is the first work in the literature to take overhearing into consideration in multicast routing for such networks. In our protocol, paths are formed so that they tend to minimize the number of required transmissions as well as the number of nodes that overhear messages. Simulation results showed that our protocol outperformed the most energy-efficient related protocols found in the literature in terms of energy cost.
