Abstract— Wireless sensor network (WSN) have wide applications due to sensor nodes ease of deployment. But wireless sensor network are also highly vulnerable to attacks due to the nature of the wireless media and restricted resource. Sensor nodes are resource constraint devices and are thus vulnerable to a variety of attacks, which can compromise the security of an entire wireless sensor network. A generic wireless sensor network model has been created in network simulator and necessary changes have been done in the code library to simulate the attacks. Sensor measures like throughput, packets dropped, end to end delay have been recorded and the analysis has been carried out to understand the impact of these attacks. A trust sensing based secure routing mechanism with the lightweight properties and the ability to resist many common attacks simultaneously is developed in an effort to address the serious effects of typical network attacks on data transmission that are brought on by the limited energy and the poor deployment environment of wireless sensor networks. At the same time, the security route selection algorithm is also optimized by taking the trust degree and Quality of Service metrics into account. The performance analysis and simulation results show that trust sensing based secure routing mechanism can improve the security and effectiveness of wireless sensor network.
