| description | In order to improve the QoS for multimedia application,which focused on the delay-constrained and jit-ter-optimized traffic allocation problem in multipath routing.First of all,based on the network calculus theory,a deep analysis on the upper bound of delay in the single route transmission was dore,and deduce the upper bound formulation of delay and jitter in multiple route transmission,and find out the maximum income rate satisfying the delay constraint for a route.Then,based on the upper bound of delay and jitter,a delay-constrained and jitter-optimized traffic allocation algorithm DCJOTA was proposed,which distributes the traffic to a route in proportion to its maximum income rate,and does some adjustment to optimize the jitter.At last,the implement methods of DCJOTA were given to run in NS2,and simulation is done.Experimental results show that the DCJOTA embedded multipath routing protocol DCJO-AOMDV outperforms AOMDV at the term of end-to-end delay and jitter.Compared with AOMDV,DCJO-AOMDV has made the end-to-end delay and jitter decreased by 3.9% and 24.5% respectively.But,DCJOTA puts a litter complexity on the rout-ing protocol,which leads to the network throughput decreased by 1.7% in DCJO-AOMDV. |
