Degradation of Ad-Hoc Network Performance Under Wormhole Attack

Free registration required

Executive Summary

An ad-hoc network is self-organizing and adaptive. Networks are formed on-the-fly; devices can leave and join the network during its lifetime, devices can be mobile within the network, the network as a whole may be mobile and the network can be deformed on the-fly. In wireless ad hoc networks, nodes depend upon other node to forward packets for each other to communicate beyond their transmission range. Ad-hoc network are very useful in war, accidental, military services, flood, earthquake situations and also in normal conditions. In multi-hop wireless Ad-hoc networks, cooperation between nodes to route each other's packets exposes these nodes to a wide range of security attacks.
