In wireless sensor network, security is a major concern. The protection of integrity and confidentiality of information can be protected from unauthorized access is an important one. In open wireless medium and small size of sensor nodes, the implementation of security can be challenged one. In existing, they can be used QDV for securing WSN. Two parameters are used such as QOS and reputation. It takes more simulation time. In proposed, Ant colony optimization concept can be used for more securable between the two neighbour nodes and it can be providing the trusted nodes and more reliable data for communication purposes. Additionally, it can provide the scalability and computation power.
