New QoS Architecture for Ad hoc Networks
一种新的Ad hoc网络中的QoS体系结构

Due to the band allocation ability owned by MAC mechanics,DiffServ in the Ad hoc networks cannot differentiate the services perfectly.Aiming to resolve this problem,this paper presents a new architecture named Diff-EDCF that combines DiffServ and IEEE 802.11e EDCF mechanism in the Ad hoc networks,and the simulation results indicate that services under any circumstances can be differentiated when Diff-EDCF is introduced to Ad hoc networks and ideal throughput can be obtained when the parameters are modulated.
