Distributed IDS for efficient resource management in wireless sensor network

摘要

Intrusion detection system (IDS) is one of the basic components of network security. IDS can use signatures or abnormal behaviors to detect attacks. When IDS uses signatures, in order to detect more attacks, we have to implement more attack signatures on IDS. However, in resource-constrained wireless sensor networks, it is not efficient to implement all of attack signatures. And it is hard to maintain attack signature database because it should be updated frequently when new kind of attacks appear. In this paper, we propose a distributed IDS mechanism which reduces the usage of memory and overhead. Analysis of our proposal shows that our proposal requires less memory.
