Wireless sensor networks (WSN) have recently used in many applications like surveillance, military applications, etc. In such applications, the sensor nodes are expected to be work long period of time without recharging their batteries. To extend the network lifetime, some sleep scheduling techniques always used, which may cause communication delay in large scale WSNs. In this paper, we present the challenges in the design of delay efficient sleep scheduling, comparison of different approaches in terms of performance metrics and future outlook of communication delay in WSN.
