A multi-path routing technology for Ad Hoc network based on tag exchange

The invention designs a Ad Hoc network multipath route technology based on label exchange, which includes sending opposite label when sending route request information, sending positive label when sending route reply information and establishing a plurality of bidirectional label exchange routes and local node repair based on label exchange route. The protocol brings MPLS label exchange technology into Ad Hoc network and can improve the network throughput, transmission time delay and service quality and realize traffic engineering in Ad Hoc network.
