In a mobile ad-hoc network, to establish a stable routing path is one of the important technical issues to transmit data from source to destination by multi-hop transmission. Mobile ad-hoc network has time varying channels, and traffic congestion or unstable link condition can be severe problems. To solve those problems, multi-path routing protocols were proposed.
Conventional multi-path routing, however, requires much more nodes and power consumption. In this paper, we propose partial multi-path routing with interference avoidance. The proposed routing does not establish another full routing path but establish a partial multi-path to complement some poor links, and the routing paths have enough distance from each other to reduce path interference.
