Stimulating Node Cooperation in Mobile Ad hoc Networks
Mobile Ad hoc Networks (MANETs) rely on the cooperation of nodes for packet routing and forwarding. However, much of the existing work in MANETs assume that mobile nodes (possibly owned by selfish users) will follow prescribed protocols without deviation. However, a user may misbehave due to several advantages resulting from noncooperation, the most obvious being power saving. As such, the netw...
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 کاملStimulating Cooperation in Mobile Ad Hoc Networks
Consider a mobile ad hoc network (MANET) where packet transmissions occur between mobile nodes. Such a network requires that the nodes act as relays to form multi-hop routes connecting the origin-destination node pairs that are out of radio transmission range with respect to each other. If the nodes do not to belong the same authority, then the nodes must be given an incentive to spend their re...
متن کاملCooperation in Mobile Ad Hoc Networks
In this report we consider selfish node behavior in ad hoc networks and discuss trust and reputation mechanisms that will stimulate cooperation between nodes. We propose a Locally Aware Reputation system that addresses selfish behavior by using locally available information.
متن کاملCooperation in Wireless Ad Hoc Networks
In wireless ad hoc networks, nodes communicate with far off destinations using intermediate nodes as relays. Since wireless nodes are energy constrained, it may not be in the best interest of a node to always accept relay requests. On the other hand, if all nodes decide not to expend energy in relaying, then network throughput will drop dramatically. Both these extreme scenarios (complete coope...
