Scheduling Scheme Based on Estimated-Delay in Wireless Sensor Network

ABSTRACT

In the low duty cycle wireless sensor network with unreliable link quality, how to meet designated delay requirements and maximize network lifetime is the focus of this study. This paper proposes the Scheduling Scheme based on Estimated-delay(SSE), which could satisfy decreasing energy consumption as well as delivery delay in the low duty cycle wireless sensor network by utilizing the estimated-delay from the current node to the destination node. We compare our SSE algorithm with other algorithms in the simulation. The results show that SSE could significantly improve the performance in the low duty cycle wireless sensor network compared with other algorithms at the same required delay.
