Performance Analysis 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 the 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, which are independent of synchronization between nodes, and their performances are investigated in different metrics. Then, a new metric is proposed which investigates the latency of adjacent nodes in wireless sensor networks and the performances of all discussed methods in the paper are studied using the proposed metric. Finally, the best and worst methods based on different metrics are introduced.
