Rate adaptive cooperative multichannel directional MAC protocol for ad hoc networks

Abstract

Data rate adaptive cooperative multichannel directional medium access control (RA-CMDMAC) protocol is proposed here for wireless ad hoc networks. To address the deaf-ness and hidden node problems, existing directional multichannel MAC requirements include-network-wide synchronization, multiple radios, cooperation among nodes etc. However, such features mostly experience with large overhead, higher delay and lower throughput. RA-CMDMAC is an asynchronous single-radio protocol targets to solve those mentioned problems using variable directional data transmission range and data rates. In compare to recent context, proposed protocol shows a significant improvement in terms of reducing overhead, transmission delay and enhancement in throughput issues.
