The Wireless Sensor Networks (WSNs) are composed of nodes communicating over a wireless media, without the need for physical infrastructure. In this type of topology, all nodes cooperate to ensure the proper management of the network (control, routing, etc.). Fully distributed nature of such networks is the problem of performance (due to the calculation of routes) as well as problems related to the security of exchanges between nodes. In regard to performance due to packet routing, the authors distinguish protocols inspired by ant colonies that give in most cases, better results.
