Abstract:
This paper presents a novel method for constructing multiple routing paths based on paths which have highest cumulative residual energy. An advantage of selecting the path with highest cumulative residual energy is that it minimizes the probability that nodes along the path will deplete their energy and thus minimizes path failures in the network. The algorithm incorporates a multipath discovery phase without incurring any overhead by “piggybacking” the cumulative residual energy data to existing reinforcement packets of directed diffusion. The algorithm also updates residual energy at the highest rate supported by the network. Simulations show that the proposed method has lower residual energy variance (38%, 30% less) and longer network lifetime (85%, 32% longer) than basic directed diffusion and a load-balanced directed diffusion version which does not implement multipath routes, respectively.
