Abstract: The wireless sensor network is one of the most popular network technologies for different applications. A number of applications such as weather monitoring and geo-location tracking are implemented using the WSN technology. Due to this these networks are utilized in critical situations. Therefore, the security in the communicated data is a primary aspect of the network as the performance of the network. Therefore, in this work the wireless sensor network security is investigated and a new secure routing technique is proposed for securing the data transmitted over the network. For providing the security a Trust and Opinion based approach is employed on network. This document provides the formal overview and the solution steps which are required to incorporate with the secure routing.
