A New Proactive Routing Method with L2-Trigger Based on Cross-layer Design in MANET

The traditional way to design Mobile Ad hoc Network (MANET) routing has great limitations on account of only considering the performance and factors of the network layer itself. The popular Dynamic Source Routing (DSR) protocol used in MANET does not discover a route only until the node needs to. To solve these problems, a new Proactive Routing Method with L2-Trigger based on cross-layer design is proposed in combination with some research results on the cross-layer design. The main idea is to execute the routing procedure in advance with the introduction of L2-Trigger and the cross-layer collaboration. L2-Trigger and its indicators together with the features are introduced in this paper. The qualitative analysis of the latency and the simulation results show that the new method can decrease the latency to a greater extent and will not bring much extra overhead to the network as long as the L2-Trigger is triggered properly.
