Executive Summary

To design a routing protocol that saves sensor node energy while meeting the needs of different applications has become a research focus in wireless sensor network. In this paper, the authors propose Energy-Efficient and Delay-Constrained Routing (EEDCR) protocol, in which delay-sensitive packets are transmitted along the shortest path to minimize their end-to-end delay, while others are sent to the next hop which is selected based on local neighbor information, e.g., the remaining energy, the proportion covered by the length of data in the total length of the queue and the depth, which alleviates congestion at hot spots. The simulation results show that EEDCR reduces the average end-to-end delay, balances the energy consumption, and prolongs network lifetime.
