Novel QoS-aware Multipath DYMO Routing Protocol in Mobile Ad Hoc Networks
Hong Zhang · 2010
DYMO is a dynamic on-demand routing protocol in mobile ad hoc networks,which is a single-path routing protocol.But multi-path routing can support QoS better than single-path routing.Firstly,the advantages and problems of DYMO protocol were analyzed.Then a novel QoS-aware multi-path DYMO routing protocol(QA-DYMO) was proposed to provide QoS and multi-path routing which establishes and utilizes multiple routes of link-disjoint paths to send data packets concurrently.Finally,a QoS-aware routing algorithm was proposed.QA-DYMO can adapt to the dynamic changes of the network and support QoS better.The simulation results show that the proposed protocol outperforms other pertinent protocols.
