Security is the most questing issue in Wireless Sensor Network (WSN) now because of various attacks on mobile nodes. Since existing security mechanisms are inadequate, new ideas are needed to effectively address the wireless sensor network security. Since a low energy node is more prone to security attacks, secure routing algorithms that consume less energy for communication should be used. Most of the real-world wireless sensor networking applications requires a certain amount of trust in their application in order to maintain proper network functionality. WirelessHART is an emerging secure and reliable communication standard that aims in maximizing the utilization of wireless communication. This paper employs the WirelessHART communication protocol for secure communication between two nodes. The WirelessHART standard is implemented on individual sensor nodes to ensure security. To reduce the communication overhead, hierarchical clustering is performed and sensor nodes are allowed to communicate only based on their trust value.
