| Abstract | We study the problem of greedy, single path data propagation in wireless sen-sor networks, aiming mainly to minimize the energy dissipation. In particu-lar, we first mathematically analyze and experimentally evaluate the energy efficiency and latency of three characteristic protocols, each one selecting the next hop node with respect to a different criterion (minimum projection, minimum angle and minimum distance to the destination). Our analytic and simulation findings suggest that any single criterion does not simultane-ously satisfy both energy efficiency and low latency. Towards parameterized energy-latency trade-offs we provide as well hybrid combinations of the two criteria (direction and proximity to the sink). Our hybrid protocols achieve significant performance gains and allow fine-tuning of desired performance. Also, they have nice energy balance properties, and can prolong the network lifetime. |
