Low energy consumption has always been the most important main issue in wireless sensor networks. But many applications requiring low latency and high throughput have been emerged recently. Many existing duty-cycle Medium Access Control (MAC) protocols such as S-MAC and T-MAC provide good power efficiency but introduce significant end-to-end delay. In this paper, the authors proposed an energy and delay efficient duty-cycle MAC protocol which reduces data transmission delay from source node to destination node and node energy consumption in multi-hop wireless sensor networks.
