Towards Optimal Monitoring in Cooperative IDS for Resource Constrained Wireless Networks
The problem of cooperative intrusion detection in resource constrained wireless networks (e.g., adhoc, sensor) is challenging, primarily because of the limited resources available to participating nodes. Although the problem has received some attention from the research community, little is known about the tradeoffs among different objectives, e.g., network performance, power consumption, delay in information being collected and security effectiveness. This paper proposes, to the best of the authors' knowledge for the first time, to distribute cooperative intrusion detection functions that take into account, simultaneously, multiple objectives. They formulate the problem of identifying the type of intrusion detection each node runs as a multi-objective optimization problem and motivate/develop a genetic algorithm to solve it.
