Abstract

Abstract : A multi‐channel medium access control (MAC) is proposed for dense wireless ad‐hoc networks, called MSR‐MMAC, which aims to enhance throughput by introducing multi‐slot reservation into multiple channels environment. Based on the integration of carrier sense multiple access with collision avoidance and time division multiple access, MSR‐MMAC alternately implements contention‐based channel access and multiple reservation‐based data transmission on a certain frequency channel. Besides, the authors build an enhanced Markov model to analyse the throughput performance of the proposed MSR‐MMAC protocol, which is further validated by extensive simulations using ns‐2. Simulation results show that the proposed MSR‐MMAC protocol reduces the average collision probability and improves throughput significantly.
