MOBILE INFORMER BASED COLANDER SCHEME FOR DATA DISSEMINATION IN WIRELESS SENSOR NETWORKS

Wireless Sensor networks are composed of huge number of motes having less energy, memory and computational resources. They are having short range of transmission or communication deployed in hostile environments such as battlefields to monitor the activities of adversaries. Incorporation of security protocols in such networks is a challenging task due energy constrained environment. So that sensor networks are vulnerable to various types of malicious attacks. One such attack is false report injection, in which attackers inject false data reports of events those are never occur, tampered readings and duplicate readings. These type cause false alarms at the base station and drain out the energy at redirector nodes. Therefore, it is very important to design a dynamic quarantine scheme to filter these attacks or at least alleviate their impact on wireless sensor networks. Proposed system addressing the some of the issues related to the false report generation, detection and reduction. A novel mobile informer mechanism is introduced at network administrator level to cross check the behaviour of the base station and other nodes at each level. The simulation results show the reduction in the false report generation and increased detection capabilities and isolation of compromised nodes
