Autonomous dynamic transmission scheduling based on neighbor node behavior for multihop wireless networks

Abstract

Multihop wireless networks (MWNs) can dynamically extend the coverage area of wireless local area networks (LANs). Communication performance of MWNs that use a single channel decreases due to interference between nodes occurring when frames are being relayed. In this paper, we proposed an autonomous dynamic transmission scheduling scheme for MWNs that is based on the behavior of neighbor nodes. In our proposed scheme, each node has a transmission priority obtained by monitoring neighboring nodes. Because it is difficult for low priority node to obtain the right to transmit a frame, the proposed scheme can mitigate interferences among nodes. In this paper, we evaluate the proposed scheme by performing simulations, and show that it can improve performance in MWN communications.
