✦ Synopsis

Data propagation in wireless sensor networks can be performed either by hop-by-hop single transmissions or by multipath broadcast of data. Although several energy-aware MAC layer protocols exist that operate very well in the case of single point-to-point transmissions, none is especially designed and suitable for multiple broadcast transmissions. In this paper we propose a family of new protocols suitable of multi-path broadcast of data, and show, through a detailed and extended simulation evaluation, that our parameterbased protocols significantly reduce the number of collisions and thus increase the rate of successful message delivery (to above 90%) by trading off the average propagation delay. At the same time, our protocols are shown to be very energy efficient, in terms of the average energy dissipation per delivered message.
