Potential Field Based Routing to Support QoS in WSN

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 Delay-Guaranteed Energy-Efficient Routing (DGEER) 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.
