Geographic Routing in IEEE 802.11 Wireless Networks With Channel Width Adaptation

In this paper, the authors propose two geographic routing metrics applied to wireless mesh networks that consider the use of channel width adaptation. The proposed metrics are evaluated through simulations jointly with a next hop channel width selection algorithm. The results show that the proposed metrics and algorithm generate greater throughput values when compared with existing geographic routing metrics. Selecting routes of higher throughput in wireless networks is a goal that has been treated in many works. Most of the previous work proposes topology-based routing algorithms and protocols.
