DYNAMIC TRUST BASED STRATEGY TO RESIST COOPERATIVE BLACKHOLE ATTACK IN MANETs
ثبت نشده
چکیده
MANET is multihop infrastructure less network which is characterized by dynamic topology due to node mobility, limited channel bandwidth and limited battery power of nodes. Since mobile nodes in Mobile ad hoc network can move arbitrarily the topology may change frequently at unpredictable times. Transmission and reception parameters may also impact the topology. The routing algorithm must react quickly to topological changes as per the degree of trust of a node or a complete path between a source and a destination pair. Nodes in mobile ad hoc network communicate over wireless links. Therefore efficient calculation of trust is a major issue in mobile ad hoc networks because an ad hoc network depends on cooperative and trusting nature of its nodes. As the nodes are dynamic the number of nodes in route selection is always changing thus the degree of trust also keep changing. Survival of ad hoc networks depends on cooperative and trusting nature of its nodes.

Mobile Ad-hoc network (MANET) is a self-configuring and infrastructure-less network of mobile nodes which are connected to each other without wires. Each node in a MANET moves freely and independently in any direction and this leads to a frequent change in their location and dynamic topology of the network. The structure-less architecture of Mobile Ad-Hoc Networks (MANETs) allow various attacks...
