Implementation And Evaluation Of Cluster-based Ad Hoc Multicast Routing Protocol

Ad Hoc wireless mobile network pay close attention to the thing with flexibilityand practicability their a more and more one in recent years, various kinds of Ad Hocnetwork route protocols get out of and relevant analysis of performance become thefocus of studying of academia too to appraise. With multicast business growth ofdemand, emerge a lot of multicast route protocols to Ad Hoc network successively.Present Ad Hoc these multicast protocols have good performance when there are onlya few nodes and the network moving is not strong more. So the large-scale mobile AdHoc network in the actual conditions needs high-efficient route protocol even more.Now, for solve large-scale Ad Hoc network multicast routing, is it form a clusteralgorithm most effective solution to divide. The thesis has carried on the survey to AdHoc and network route protocols at first, have recommended the classification of thenetwork route protocols and some of Ad Hoc network multicast routing protocolsspecial-purposely, have explained the mechanism of the ODMRP relatively excellentperformance in Ad Hoc network emphatically. Tell realization mechanism of EWCAespecially, and with it form a cluster-based ODMRP.The author of this thesis utilizes the simulation means of software. The thesiscompares route performance of ODMRP and CODMRP finally. CODMRP have moreexcellent route performance than basic ODMRP. The simulation result has shown theperformance of basic ODMRP of improvement of this kind of thought all in variousdegree, with the constant increase of the nodal quantity in the scene, the delivery ratethat the data packet is improving constantly, represented very strong expansion ability,etc. too at the same time. So, have better adaptability to the extensive mobile networkon the basis of EWCA algorithm improved CODMRP agreement.
