Detection of Vampire Attack in Wireless Ad- hoc Network
Mobile ad-hoc network is an infrastructure-less network in which the routing operation play important role in route discovery between communicating nodes. Due to infrastructure-less characteristic of ad-hoc network, it has different issues like routing, MAC layer, security etc. One of them is security issue which needs more concern. Vampire attacks modify targeted packets. It does so by prepari...
متن کاملinvestigating the effect of black hole attack on aodv and dsr routing protocols in wireless ad hoc network
wireless ad hoc networks are composed of independent nodes managing the network without any infrastructure. the connection between nodes is provided by sending packages and by trusting to each other. therefore, using efficient and certain protocols is the essential requirement of these networks. due to special characteristics of wireless ad hoc networks such as lack of a fixed infrastructure, t...
متن کاملA Hidden Node Aware Network Allocation Vector Management System for Multi-hop Wireless Ad hoc Networks
Many performance evaluations for IEEE 802.11distributed coordination function (DCF) have been previouslyreported in the literature. Some of them have clearly indicatedthat 802.11 MAC protocol has poor performance in multi-hopwireless ad hoc networks due to exposed and hidden nodeproblems. Although RTS/CTS transmission scheme mitigatesthese phenomena, it has not been successful in thoroughlyomit...
متن کاملDDoS Attack and Defense Scheme in Wireless Ad hoc Networks
The wireless ad hoc networks are highly vulnerable to distributed denial of service(DDoS) attacks because of its unique characteristics such as open network architecture, shared wireless medium and stringent resource constraints. These attacks throttle the tcp throughput heavily and reduce the quality of service(QoS) to end systems gradually rather than refusing the clients from the services co...
متن کاملThwarting the Sybil Attack in Wireless Ad Hoc Networks
The present document is essentially a summarized version of the dissertation that will be developed within the scope of an MSc degree in Communication Networks, in the area of security in wireless ad hoc network. Wireless ad hoc networking is a technology that allows fast, easy, and inexpensive network deployment. Unfortunately, these advantages also make the task of an attacker simpler, as it ...
