Abstract :
A wireless ad-hoc network consists of wireless mobile terminals forming a temporary network without any deployed infrastructure or centralized administration. Energy efficiency is an important issue in wireless ad-hoc networks because the battery power of terminals is limited. We propose an energy efficient MAC algorithm based on reservation and scheduling for wireless ad-hoc networks. We evaluate the performance of our proposed MAC scheme with respect to the number, of delayed slots, the channel utilization, and the energy efficiency. Then, we derive the fair threshold energy level for the pseudo base station (PBS) reselection in the proposed MAC.
