Objectives: The work is to identify the Quality of Service metrics for mobile ad hoc networks during hacking and counter hacking mechanism. Methods: The various quality metrics such as end to end delay, throughput and packet delivery ratio is determined. The implementation is done using ns2 simulator with the nodes at random waypoint mobility model. The performance is measured during intruder attack and counter attack for 20 nodes with 1000 packets of 512 bytes size. Findings: The simulation results showed a significant increase in packet delivery ratio for counter attack mechanism (98) when compared with intruder attack, which gave least value (40.6). This work is also compared with Anti Black Hole Mechanism and is found to be efficient in terms of packet delivery ratio. Improvements: In this work, all the nodes are assumed to be of maximum energy in terms of its battery power. While routing the energy drops and this is a major issue in ad hoc nodes. The future work will focus on energy efficiency during routing process.
