A Hotspot-based Protocol for Attack Traceback in Mobile Ad Hoc Networks

摘要

Based on the principle of divide and conquer, in this pa per we propose an efficient traceback protocol for mobile ad hoc networks, The protocol is capable of detecting a hotspot where the attacker resides. It works by dividing the forwarding path of every packet into multiple interweaving fragments and each reachable fragment is individually recon structed during a traceback process. Through simulations in theoretical mobility models as well as real mobility traces, we show that each traceback of our scheme can attribute to a very small hotspot and the attacker can be accurately identified after a number of traceback operations.
