Improved TEEN based trust routing algorithm in WSNs

Deployed in harsh environment of wireless sensor network node is physically captured or damage easily, and its wireless communication pattern may lead network vulnerable by all kinds of interference and attacks. Therefore, the routing security is particularly important. Based on the in-depth analysis of wireless sensor networks protocol - TEEN protocol, combined with the trustworthy evaluation mechanism, an improved TEEN based trust routing algorithm in wireless sensor networks is put forward. A dynamic trust management mode is designed to ensure the credibility of node. The cluster head selection strategy and routing strategy of TEEN are improved to ensure the energy efficiency of the network, and the periodic data collection mechanism is introduced to determine the survival state of node. The simulation and performance evaluation show that the proposed algorithm has better performance.
