Abstract
This paper presents a Cross-Layer Enhanced Adaptive Reservation (CLEAR) protocol. CLEAR supports heterogeneous packet transmissions over a wireless channel with multi-packet reception. Reservations are assigned using a genetic algorithm based on the quality of service requirement and channel condition. In other words, heterogeneous packets are mixed effectively using intelligent computing. CLEAR also supports cross-layer operations. Basically, when the channel condition becomes bad, the upper layer(s) can respond accordingly to reduce the effect and energy consumption. Furthermore, reservations are changed adaptively using a genetic algorithm based on the new channel condition. To evaluate the performance of CLEAR under the consideration of energy and quality, we employ a performance metric called the energy quality index (EQI). Simulation results are presented to demonstrate the effectiveness of the CLEAR protocol based on the traditional packet loss ratio (PLR) as well as the EQI.
