QoS Issues Reserch Based on Mobile Ad Hoc Network
GU Hai-jun · Journal of Jilin University · 2006
Make an in-depth study of some problems in Mobile Ad Hoc networks such as commu nication failure,delay,jitter,etc,due to break of QoS(Quality of Service) pat h caused by free movement of mobile node and dynamic change in topology,also ta ke a depth discussion on QoS signaling mechanism that enable to support ad hoc n etworks.Then it discussed the advantage and disadvantage of existing computer n etwork integrated services and differentiated service used in ad hoc networks ba sed on problems such as dynamic change in topology of ad hoc networks,transmissi on bandwidth and energy is limited,etc.We think that the design of QoS signalin g of ad hoc network need to consider.Research shows that function of protocol wi th MRSVP(Mobile Resource ReSerVation Protocol) and DRSVP(Dynami Resource ReSe rVation Protocol) have had more greatly enhanced than RSVP(Resource ReSerVatio n Protocol),and FQMM(Flexible Quality of Service Model for Mobile Ad Hoc Networ ks) combines the advantages IntServ and DifServ,all of them has played a signif icant role on improving the QoS of networks.
