All links in mobile ad-hoc networks are wireless and works independently, as there is no fixed infrastructure. In mobile ad-hoc network, network topology may change rapidly. The basic reason is the mobility of nodes, so it requires more security. This paper basically discusses the black hole attack, collaborative black hole attack & the technique to detect and isolate these types of attack. The collaboration of two proposed techniques i.e. fake route request with fake destination ID and multipath routing is implemented that helps in detection of black hole attack. These attacks may lead to the degradation of performance of the network. The algorithm implemented will improve the packet delivery by 25% and delay factor by 50% as compared to the conventional techniques. We also compared the results such as routing overheads, packet loss, energy consumption and throughput.
