An Optimization Multi-path Ad Hoc Network Routing Protocol Based On Mobility Prediction

The dynamic topology and the opened channel in Ad Hoc network easily lead to link instability, link interrupt and even data loss. So the routing protocol designed should adapt to the dynamic topology and take advantage of the valid paths. A backup multi-path protocol based on kalman filter in mobility prediction model is proposed. The multi-path routing algorithm is used to find one backup route, and the mobility prediction algorithm based on kalman filter is developed to predict the link quality of the nodes in the next time, then a more stable route can be selected. At last, the new protocol with OLSR is simulated in QualNet, simulation comparison illustrates, the new protocol increases the average delivery rate, decreases the time that the packets stayed in the queue and decreases the average end-to-end delay.
