The goal of this paper is to introduce two trust methods for routing in wireless sensor networks. The two methods consider transitivity of trust. When computing routing trust value, we use optimistic and pessimistic ways respectively. These trust methods can select a trust routing for precise data transmission. Simulations for optimistic method show the trust model has a higher performance than ECCR...
Wireless Sensors Networks (WSNs) are susceptible to many security threats, and because of communication, computation and delay constraints, traditional security mechanisms cannot be used. When trust system is established, the route from source node to destination node should consider nodes' trust on the road but not only QoS. In this paper, we propose a routing model in trust WSNs with respect to...
In WSN, in order to ensure security, establishing trust in a clustered environment can provide numerous advantages. While trust value depending on multi-factors, we propose a trust model which considers communication quality, data similarity and energy to measure trust between two nodes. With comparing our model with TMS, we conclude that our model is more accurate and sensitive with detailed parameters.
In this paper, it has been deeply analyzed and studied the safety measurement to bus insulation resistance in the production of smelting for long-term. According to the specific system characteristics, it has brought forward the test method of introducing filter module and the equivalent resistance while program-controlled amplifiers and high-precision A/D have been combined use. It made the measurement...
