Retransmission control method using location information in MANET

In mobile ad hoc networks, each node can communicate with disconnected nodes by multi-hop transmission. In wireless communication, flame transmission failures occasionally occur due to obstacle, radio wave interference, moving of node, and so on.

Description
Summary:In mobile ad hoc networks, each node can communicate with disconnected nodes by multi-hop transmission. In wireless communication, flame transmission failures occasionally occur due to obstacle, radio wave interference, moving of node, and so on. In IEEE802.11 MAC, a retransmission process is executed when such a failure occurs. However, there is a possibility that retransmissions continuously fail because link status is not considered. In this paper, we propose a retransmission control method in order to solve the above problem. In this method when a packet transmission fails, an overhearing node retransmits the packet to more suitable node than the original destination. From computer simulation, we show effectiveness of the proposed method in terms of packet loss rate.
