Centralized Monitoring System to detect Black hole Attack in MANET

A NEW APPROACH OF SURVIVABLE MULTICAST ROUTING PROTOCOL IN MOBILE AD-HOC NETWROK

1Presented by:Ariful Islam, ID:090212,Al Hizbul Bahar, ID:090225To ensure the survivability of sub sources.To reduce the maintainance cost of the network.To ensure data transfer among all the nodes in a network.The data packet delivery ratio must be sufficiently highThe data transmission delay must be as less as possible.2Objectives of Research3Collection of self configurable mobile node connected through wireless linksWithout aid of any existing network infrastructure or central access pointEach node participating in the network acts both as host and a routerCharacteristics of MANETs : dynamic topology node mobility large number of degree of freedom self-organizing capabilityWhat is MANETNode mobility in an ad hoc network causes frequently change the network topology.

ADEFIGHConclusionThe existing system is working well with main source. But in the absence of that main soure hole system will be damaged. We proposed a solution in this case of problem, where main source will be absence and sub-source are connected with each other when they want to send data in a network.

Hence nodes are dynamic and infrastructure less ,there is a great challange in this way of solution.To overcome these challange, a specific node will query a neigbour node in multicast network and send ROUTE REQUEST. Repeating this process data transfer between two node will be done.14References[1] G.Vijaya Kumar et. al. / (IJCSE) International Journal on Computer Science and EngineeringVol. 02, No. 03, 2010, 706-713[2] M.S.
