For many applications of the mobile ad hoc networks (MANETs) deployed in adversary environments, anonymous communications with data confidentiality and integrity is important. A major requirement is to provide unidentifiability and unlinkability to the mobile nodes and their traffics.The existing protocols are vulnerable to security threats like global eavesdropper attacks, fake routing packets...

In recent years mobile networks have expanded dramatically, compared with other wireless networks. Routing protocols in these networks are designed with the assumption that there is no attacker node, so routing protocols are vulnerable to various attacks in these networks. In this paper, we review the network layer attacks and then we simulate the impact of black hole attack on ad hoc on demand...

the establishment as well as the survival of mobile ad-hoc networks relies on the cooperation of nodes for performing network operations such as routing and packet forwarding. in these networks, misbehaving nodes can severely degrade network’s performance by not cooperating in networking operations. in this paper, we study the issue of node misbehavior in packet forwarding. to counter this type...

In Mobile Adhoc Networks (MANETs), routing attacks are considered as a serious issue. However, in the presence of malicious nodes, the networks are affected by various kinds of attacks. The malicious node(s) can attack a MANET in different ways, such as sending fake messages several times; fake routing information and advertising fake links to disrupt routing operations. Black hole attacks are ...

in this paper, we propose a scheme to improve existing ad-hoc on-demanddistance vector (aodv) routing protocol by discovering and maintaining multiplenon-overlapped routes. our routing protocol is a multipath version of aodvrouting protocol that considers only the disjoint path. due to non-overlappingamong paths, when a link breaks in the network, only one of paths is expired. thepresented rout...

Source location privacy is one of the most challenging topics in security WSN. Wireless Sensor Networks have been widely used in many areas for various infrastructure monitoring, tracking and information collection. We are generated more fake node, fake packet and to create anonymity node for source location privacy. They are providing privacy to the event detecting, tracking sensor node and in...

mobile ad hoc networks (manets) are composed of mobile stations communicating through wireless links, without any fixed backbone support. in these networks, limited power energy supply, and frequent topology changes caused by node mobility, makes their routing a challenging problem. tora is one of the routing protocols that successfully copes with the nodes’ mobility side effects, but it doesn’...
