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.
