Proposal of a zone disjoint multi-path routing for ad hoc networks

Many researches are going on in ad hoc networks and several routing protocols have been proposed. However, these protocols are “single-path” protocols which construct only one route. In ad hoc networks, due to limitation of battery capacity and mobility of nodes, communication links are unstable. Therefore, “multi-path” protocols are desired for constructing “robust” routes. Additionally, in considering the case where interference spreads to a certain area, each path is desired to be away from other paths to some degree. In this paper, we introduce the concept of “zone”, and propose a Zone Disjoint Multi-path Routing Protocol, called ZDMR, for constructing multi-path routes which disjoint each other in a zone level. Our simulations confirm that this protocol has a higher connectivity than existing protocols.
