Multi-metrics Restricts on MPRs over Standard OLSR

Optimized Link State Routing is well-suited to large-scale mobile network on account of that all the nodes exchange information of all networks periodically. Instead of typing words to chat with others, video and voice streaming increasingly become frequently-used ways for their convenience. In this paper, we have put forward a way to guarantee a high quality of video and voice services. Some quality constraints have been made to choose multipoint relays. And we compare the improved methods with standard OLSR by OPNET. Virtual voice application has been simulated during the simulation. The results of end-to-end delay and throughput show that the improved way works well when compared with standard OLSR in some degree. The real video streaming over virtual MANET environment also proves that the modified way works better.
