Partial Multipath Routing for Mobile Ad-hoc Networks

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, multipath routing protocols were proposed. Conventional multipath routing, however, requires much more nodes and power consumption. In this paper, we propose partial multipath routing with interference avoidance. The proposed routing does not establish another full routing path but establish a partial multipath to complement some poor links, and the routing paths have enough distance from each other to reduce path interference.
