Research of multicast algorithm for throughput optimization in wireless multi-hop networks
|
Abstract:
The current algorithms of increasing multicast throughput in networks are usually aiming at improving the link rate,regardless of the degrees of the multicast tree,which is the main factor that restricts the multicast throughput.So it limits the improvement of multicast throughput.This paper studied the multicast throughput optimization problem in wireless multi-hop networks,analyzed the characteristics of wireless multi-hop networks thoroughly.On the basis of considering the effects produced by both the link rate and degrees to the multicast throughput,presented UUP_MTOA algorithm,which was applied in networks with the uniform transmission power,and UNP_MTOA algorithm,which was applied in those with non-uniform transmission power.By comparing these two algorithms with similar optimization algorithms in simulation,come to a conclusion that UUP_MTOA and UNP_MTOA algorithms can achieve higher throughput,and is available within distributed system such as wireless multi-hop network completely.
