Energy Consumption Analysis of the S-MAC Protocol with Contending Nodes under Unsaturated Conditions
Seokjin Sung, S. WOO, Kyungbaek Kim · IEICE Transactions on Communications · 2008
We analyze the energy consumption of the sensor-medium access control (S-MAC) protocol, where contending nodes exist. Because all nodes running the S-MAC within a virtual cluster always behave with a fixed frame length, the behavior should be analyzed based on its frame. Hence, reflecting the frame architecture, we first present an analytic model for the S-MAC behavior with a discrete-time Markov chain, and then we analyze energy consumption under unsaturated conditions.
