description

While wireless sensor networks continue to break new grounds in applications, favored by technological innovations, energy efficiency continues to stagnate. Duty cycling remains the most popular and effective technique used to improve energy efficiency and thus lifetime of the network. Nevertheless, duty cycling imposes temporary unavailability on the network leading to deterioration of quality of service. To take care of this rather contradicting reality, this paper proposes Sleep Relay Protocol (SREP). Network nodes are divided into sets according to their location and the sets sleep in relay within a duty cycle period. Two set formation algorithms are proposed at initiation of our proposal. We extensively test our proposal with NS2 and observe further gain in energy without deterioration of availability. Comparing our proposal with Adaptive staggered protocol confirms almost no deterioration in packet delivery ratio (PDR). Moreover, there is improvement in latency.
