Energy efficiency is a very important requirement in designing a MAC protocol for wireless sensor networks (WSNs) using battery-operated sensor nodes. We proposed a new energy-efficient MAC protocol, RIX-MAC, based on asynchronous duty cycling and receiver-initiated scheme. In this paper, we analyze the performance such as throughput, delay, and energy consumption of RIX-MAC with modeling and simulation. Our modeling is validated by comparing it with the simulation results in NS-2. As the result, we obtain average 95% confidence interval of the simulation results of this paper.
