Spatial Reusability-Aware Routing in Multi-Hop Wireless Networks

Abstract

In the routing problem in multi-hop wireless networks, to achieve high end-to-end productivity, it is important to have the best "path" from the source node to the destination node. Although a large number of routing protocols have been proposed to obtain the path with the minimum total number / time of transmission to send one packet, it is not possible to reduce the number of transmission / time to the minimum of the protocols to maximize the end-to-end throughput . In this paper, we say that by carefully considering the spatial reuse of wireless media, we can improve overall productivity in multi-hop wireless networks. To support our discussion, we suggest that the SASR and SAAR protocols be routed, compared to the current one-way routing and anypath routing protocols, respectively. Our evaluation results show that our protocols significantly improve end-to-end productivity compared to existing protocols. Specifically, for single-track routing, intermediate output gain reaches 60%, and for each pair of destination sources, output gain is 5: 3; for routing a path, the maximum profit rate is 71.6%, while The average gain is up to 13.2%.
