Abstract

Most applications of sensor nodes are in hazardous areas, inaccessible or hostile environments.    Therefore, the need for security in these networks is essential. Trust methods are powerful tools for        diagnosing unexpected behavior of nodes (malicious nodes or failure nodes). In this paper, we have       proposed TBSI trust model whose main features are low computational overhead, low energy consumption and confronting attacks in WSNs. This model is simulated and evaluated by NS-2 simulator and its behavior has been evaluated based on the results of these simulations. Examining practical results shows that       energy consumption, routing overhead, and the time of death of nodes are reduced and the rate of packet delivery to the base station is increased. These desirable outcomes prove that using the method of trust to achieve a secure network is a good solution to solve security issues in wireless sensor networks.
