Core: a collaborative reputation mechanism to enforce node cooperation in mobile ad hoc networks
Countermeasures for node misbehavior and selfishness are mandatory requirements in MANET. Selfishness that causes lack of node activity cannot be solved by classical security means that aim at verifying the correctness and integrity of an operation. We suggest a generic mechanism based on reputation to enforce cooperation among the nodes of a MANET to prevent selfish behavior. Each network enti...
متن کاملStimulating 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 hybrid routing method for mobile ad-hoc networks
mobile-ad-hoc-networks (manets) are self-configuring networks of mobile nodes, which communicate through wireless links. the infrastructure of a mobile ad hoc network (manet) has no routers for routing, and all nodes must share the same routing protocol to assist each other when transmitting messages. the main issues in manets include the mobility of the network nodes, the scarcity of computati...
متن کاملA Survey of Solutions to Protect Against All Types of Attacks in Mobile Ad Hoc Networks
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...
متن کاملMODSPIRITE: A Credit Based Solution to Enforce Node Cooperation in an Ad-hoc Network
In an Ad-hoc network, node cooperation is an important factor for successful data transmission among nodes. Most of the routing protocols are based on the assumption that the intermediate node cooperates during data transmission from source node to destination. However, because mobile nodes are constrained by limited energy, bandwidth and computational resources, a node sometimes behaves as sel...
