SACOM: Secure Ant Colony Optimization for MANETs

Abstract

-Ant colony optimization (ACO), a swarm intelligence technique takes inspiration from the foraging behavior of some ant species. These ants deposit pheromone on the ground in order to mark some favorable path that should be followed by other members of the colony. Ant colony optimization exploits a similar mechanism for solving routing problem in MANETs. Mobile ad hoc networks (MANETs) are infrastructure-less networks consisting of wireless mobile nodes which are organized in peer-to-peer and autonomous fashion. Initial work in ad hoc routing using ACO has considered only the problem of providing efficient mechanisms for finding paths in very dynamic networks, without considering security. Because of this, there are a number of attacks that hinders the systems normal behavior. In this paper we introduce SACOM framework which incorporates security mechanisms into routing protocols using ACO for ad hoc networks. In addition, SACOM is developed for preventing Wormhole Attack in the system without using specialized hardware.

Enhanced ANTSEC framework with cluster based cooperative caching in mobile ad hoc networks

“…Effective and efficient learning of the pheromone tables was accomplished in the AntHocNet algorithm, which is a combination of path sampling and bootstrapping [3], [4]. The routing overhead is low in this design.…”

“…The ant colony optimization (ACO) routing protocol has provided the best paths in dynamic networks without considering security issues. SACOM [3] integrates security mechanisms and routing protocols using ACO for ad hoc networks. It provides security against attackers and depends only on efficient asymmetric cryptography.…”
