Performance Analysis of the Sleep/Wakeup Protocol in a Wireless Sensor Network

In this paper, the authors study a one-hop WSN system for digital transmission with a setup to capture the working principle of such a sleep/wakeup protocol as a discrete-time multiple vacation queueing model and also consider the WSN system by taking into account the switching procedure between the sleep mode and the active mode at sensor nodes. They present a new effective analysis method to give the formulas for performance measures in terms of the handover ratio, the average latency of data frames and the average energy consumption of the sensor node. They also present numerical results to discuss the relationship between the system performance and the modulation constellation size.
