Summary form only given. Several routing protocols, e.g. DSR(dynamic source routing protocol) and AODV(ad-hoc ondemand distance vector routing protocol), have been proposed for routing data packets in ad hoc networks. These are ondemand routing protocols. Only when a node requires to transmit data packets, it searches a route to a destination node. In addition, these are single-path protocols which detect only one route. However, in an ad hoc network, due to mobility of nodes and instability of communication links, multiple-route protocols are required. Here, we propose a novel multiple-route protocol MRAODV(multiple-route ondemand distance vector routing protocol) where separated reverse path fragments are connected to achieve additional routes. According to simulation results, more additional routes are detected in our protocol than MNH protocol.
