  • 摘要:Mobile ad-hoc network is a form of full self organize with distributed independent network, that is treat as a dynamic behavior as well as node moves randomly in free environment and routing decision is on demand bases, that MANETs face number of challenges name as security, energy, distributed independency node movement control as well as routing failure problem. So in this thesis focus on challenge security issue and control it, take Sybil attack and protect them. Due to the complex nature of MANETs and its resource constraints nodes, there has always been a need to develop insubstantial security solutions. Since MANETs require a unique, distinct, and determined identity per node in order for their security protocols to be feasible, Sybil attacks pose a serious threat to such networks. A Sybil attacker can either create more than one identity on a single physical device in order to launch a coordinated attack on the network or can change identities in order to weaken the detection process, thereby promoting lack of accountability in the network. So, design lightweight cooperative scheme for provide secure communication as well as detection of Sybil attacker in two different scenarios, and finally analyze the network behavior using network simulator with packet delivery ratio analysis, throughput, routing overhead as well as attacker identification base. Protection approach better perform if Sybil Attacker node present in simulation system
