Proposal of traffic aware routing based on neighborhood communication for ad-hoc networks

In this paper, we propose a traffic aware routing protocol for ad-hoc networks. In the proposed protocol, nodes estimate the utilizable wireless resource for constructing routes. Moreover, they consider the neighbor traffic according to the route requested connection. In order to achieve the above objects, nodes always sense a wireless channel to confirm the channel condition. Then, they remove the traffic of route requested connection from measured data to estimate the utilizable wireless resource without own connection traffic. To construct routes based on the measured traffics, nodes select forwarding delay period according to the utilizable wireless resource. From simulation results, we can find that the proposed protocol can improve the packet delivery ratio according to dispersed traffic.
