Maximum Expected Delay: A New Metric to Analyse the Performance of Asynchronous Quorum-based Protocols in Wireless Sensor Networks

Energy management is a crucial challenge in wireless sensor networks. To date, many techniques have been proposed to reduce energy consumption. Duty cycle methods reduce the energy consumption of wireless sensor networks since energy consumption declines in the sleep mode. Using quorum-based methods, sensors can stay in the sleep mode and be awaken periodically to send and receive data from adjacent nodes. In this paper, we review a subset of these methods called asynchronous quorum-based methods, independent of synchronization between nodes, and investigate their performances in different metrics. Then, we propose a new metric to investigate the latency of adjacent nodes in wireless sensor networks. Next, we study the performances of all discussed methods using the proposed metric. Finally, we introduce the best and worst methods based on different metrics.
