Reliable and energy-efficient routing protocol in dense wireless sensor networks
Delivering sensed data to the sink reliably in sensor networks calls for a scalable, energy-efficient, and error-resilient routing solution. In this paper, a reliable energy-efficient routing (REER) protocol is proposed to achieve the above goals for dense wireless sensor networks (WSNs). Based on the geographical information, REER's design harnesses the advantage of high node density and relies on the collective efforts of multiple cooperative nodes to deliver data, without depending on any individual ones. We first select reference nodes (RNs) between source and sink. Then, multiple cooperative nodes (CNs) are selected for each RN. The reliability is attained by cooperative routing: each hop keeps multiple CNs among which any one may receive the broadcast data packet from the upstream hop to forward the data successfully. The distance between two adjacent RNs provides a control knob to trade off robustness, total energy cost and end-to-end data latency. The main difference betw...
