Abstract

In this paper, we propose the multichannel variable-radius multiple access (M-VRMA) scheme for power-controlled multichannel medium access control (MAC) in mobile ad hoc networks. We propose the RTS/object-to-sending (OTS)/VP-CTS (ROV) protocol based on M-VRMA, multiple access with lag time, OTS, and VP-CTS for efficient variable-radius supports in heterogeneous ad-hoc networks, without relying on busy-tone or any mechanisms that require expensive specialized hardware or more than one transceivers per device. Our simulation results demonstrate that for the same radio bandwidth, ROV can achieve considerably higher throughput as compared to fixed-radius IEEE 802.11 or previous power-controlled RTS/CTS protocols without variable-radius supports.
