ARX For Trust Management In Wireless Sensor Networks

As we all know that the wireless communication technology develops very fast in the21th century. Wireless sensor network is easy to decorate, with good anti-destruction, with reasonable price and so on. With all these advantages, it becomes more and more popular. Its application field has covered national defense military, industrial and agricultural control, family health, etc. With the attention improved, the security has become one of the most important problems. The potential risk of wireless sensor network comes from both inside and outside. In this paper, we focus on the malicious nodes and the selfish nodes from the inside risk.In the paper, first we introduce the background and the purpose of this paper. Second we introduce the original ARX model, and base on the original model we propose a novel trust management scheme for improving the routing reliability in the wireless sensor networks. In the model, we can redefine the direct trust and indirect trust, and verify and adjust the model. Third, we bring this new trust management scheme into trust-based routing. Different from the traditional geographic routing, trust-based routing take both distance and trust in consideration. In other words, we will choose the node that has the highest trust value from the nearest node. At last, we use the MATLAB platform to evaluate the performance of the scheme when an ARX and RFSN model is used.Based on the MATLAB2011development platform, we design and carry out the ARX trust management model for wireless sensor network. Through the simulation we find out that the model can provide more accurate on finding the malicious and selfish nodes, and has improved in both packet drop rate and forecast trust value. It is a better trust-based routing and has a good application prospects.
