A Distributed Procedure for Carrier Sensing Threshold Adaptation in CSMA-Based Mobile Ad Hoc Networks
Benedito J. B. Fonseca · IEEE Vehicular Technology Conference · 2007
This paper discusses the problem of determining the carrier sense threshold (CSth) of nodes in a CSMA-based Mobile Ad Hoc Network (MANET) and proposes a practical, fully distributed, CSth adaptation procedure. The procedure enables a node to select its CSthin order to improve the data throughput of the system by maximizing the number of successful transmissions in its neighborhood. Simulation results show that the procedure is able to improve the data throughput in more than 85% of random topologies. The average throughput improvement over all topologies were 11% and 18% in two different scenarios, with some topologies showing up to 75% data throughput gains.
