Loop-based source routing protocol for mobile ad-hoc networks

In an ad-hoc network, a routing protocol which detects a transmission route from a source mobile computer to a destination one is critical due to mobility and limited battery capacity of computers. Here, a communication link between two mobile computers is not always bi-directional, i.e. unidirectional, since transmission power of mobile computers is not the same. Though some ad-hoc routing protocols, e.g. DSR, support routing with uni-directional links, multiple floodings (successive broadcasting) are used and communication overhead is high. This paper proposes a novel routing protocol LBSR supporting uni-directional links and requires only a single flooding and unicast message transmissions.
