A Security Response Approach Based on the Deployment of Mobile Agents: Limitations and Improvements

Roberto Magán-Carrión; José Camacho; Pedro García-Teodoro

Abstract:

This paper introduces a response mechanism to improve the tolerance against security threats in MANET environments. The mechanism is launched after detecting the existence of nodes with malicious behavior, and is based on the use of one or more mobile agents to improve the connectivity of the network. This way, in the event of the detection of a malicious node (e.g. a selfish node or a dropper node), a set of agents are deployed to recover and maximize the overall connectivity of the network. Every agent acts as a relaying node within the MANET and is automatically positioned according to a particle swarm optimization (PSO) process. Also, the paper introduces some improvements in the use of PSO to maximize the connectivity in comparison to previous works. The experimental results show the suitability of the approach to improve the survivability of the network from a security perspective.
