A novel approach to secure routing protocols in WSN

In recent years Wireless Sensor Networks (WSNs) are widely used and therefore it's creating critical situation for security of application. WSNs have quite a lot of constraints, like less computation capability, not as much of storage capability, controlled energy resources, power limitations, liability to physical capture, in addition to use of insecure wireless communication channels. The previous system has some issues such as low performance, low security, etc. and now for solving those problems this paper is represents the use of secure routing protocol to improve security of network. Most routing protocols are deal with simple network failures (e.g., links going up and down, nodes crashing and restarting etc.), and thus can have many insecurity when facing a strategically placed intruder. The most solemn attacks is black hole attacks which creating the problem in transferring packets. For that reason we have proposed secure and trustable routing technique with utilizing multi data flow topologies (MDT) scheme to defend against this attack and proposed a suite of optimization methods to minimize the energy cost while keeping the system's security in a sufficient level. Concept is efficiently and effectively schedule tasks depending on sensor nodes' locations and target nodes' trustworthiness. Using that choose the trusted node for security purpose. And that's why in that optimizing the network lifetime and success in security of packets behind the black hole attacks.
