Free registration required

Executive Summary

In mobile ad hoc networks, collision problem which is caused by the expansion of the interference range of the receiver node due to the controlled transmission power of the sender node is uniquely a tarnished problem. This paper employs physical and virtual carrier-sensing schemes to avoid the collision problem. The authors analyze the relationships among the transmission range, the carrier-sensing range, and the interference range in case power control is adopted, and based on the analysis; they propose a power aware range based MAC routing mechanism to prevent the collision problem from occurring in mobile ad hoc networks. This paper further analyzes the superiority of the proposed protocol under certain situations with the conventional DSR and AODV routing protocol.
