Pattern Matching Intrusion Detection Technique for Wireless Sensor Networks

Wireless Sensor Network (WSN) is a network with large number of tiny sensor devices which are of low cost, and minimum consumption of power called as sensor nodes. These type of nodes have great sensing technology which are specifically designed for applications such as military, smart homes and other security related areas. Due its wireless nature, network can be deployed anywhere in the environment, which becomes more vulnerable for attackers to destroy the network. Most importantly, WSN should be protected from malicious activities to take place and thus security becomes a major issue. However, such security can be provided by applying mechanisms for both intrusion detection and prevention. In our study, pattern matching is one of the mechanism that can be used for security of WSN. We also discuss some of the preventive measures that can be considered for protecting the sensor network.
