TDM MAC protocol design and implementation for wireless mesh networks

摘要: We present the design, implementation, and evaluation of a Time Division Multiplex (TDM) MAC protocol for multi-hop wireless mesh networks using programmable platform. Extensive research has been devoted to optimal scheduling algorithms assuming perfect TDM protocol. However, problem designing implementing such not received due attention. introduce design framework that addresses three main challenges comprise this problem: (i) How calibrate optimize parameters given platform, (ii) how achieve network-wide synchronization with high accuracy, minimal overhead, most importantly, bounded delay, (iii) integrate algorithm state machine hardware resources. apply our platform evaluate resulting through controlled experiments in testbed. The results demonstrate protocol's ability provide fairness graceful performance degradation under packet losses traffic patterns arise network deployments.
