摘要
随着多媒体技术的不断发展,如何在Ad Hoc网络中设计合理有效的资源分配方案面临着巨大的挑战。该文联合Ad Hoc网络的网络层和链路层进行跨层设计,利用分布式牛顿法来进行资源分配,并利用Matlab对该算法进行仿真,仿真结果表明:该算法具有更快的二次收敛速度,并且收敛速度在一定的范围内可调。
With the continuous development of multimedia technology, how to design a reasonable and effective resource allocation scheme in Ad Hoc network is facing enormous challenges.This paper joint the network layer and link layer of Ad Hoc networks to realize cross layer design.Distributed Newton＇s method is used for the resource allocation, and simulate the algorithm with Maflab.The simulation result shows that： this algorithm has faster convergence speed, and the speed can be adjusted in a certain range.
