Analysis of a TDMA MAC Protocol for Wireless Ad Hoc Networks under Multipath Fading Channels

摘要

The behavior of MAC protocols for wireless ad hoc networks is conditioned by multipath fading, especially with regard to the links stability and the differences between channel errors and collisions due to interference. In this paper, we evaluate the impact of multipath fading on the performance of a TDMA proposal designed to provide QoS in wireless ad hoc networks. It lies in a frame subdivision that consists of a broadcast control phase and an information phase. We propose modifications to guarantee the reliability and efficiency of both broadcast control and data services.
