An Agent-Based Approach To Nodes? Misbehaviour Detection In Mobile Ad-Hoc Networks

摘要

Existing Misbehaviour Detection Systems in Mobile Ad-hoc Networks (MANETs) are challenged with routing overhead and high latency resulting from complexity and failure to isolate and block misbehaving nodes for the reason that it is difficult to detect them as they participate fully in route finding. In this work, a Mobile Agent-Based Acknowledgement scheme (MAACK) was formulated to address this problem using an object oriented algorithm deployed to report misbehaving nodes to the source and destination by registering the Internet Protocol (IP) address of misbehaving nodes in their header. The scheme was simulated using Network Simulator-3 (NS-3) and results benchmarked with an existing scheme; the Enhanced Adaptive Acknowledgment (EAACK) using packet delivery ratio, routing overhead and latency as performance metrics in the two scenarios. The results showed that the MAACK paradigm guaranteed a higher packet delivery ratio, lower latency and routing overhead than the EAACK scheme. The model can be adapted by Ad-Hoc network protocol developers.
