  • 摘要:

    Wireless sensor networks processing sensitive data are facing the risks of data manipulation, data fraud and sensor destruction or replacement. However, the practical deployment of sensor networks faces many challenges imposed by real-world demands. Sensors are deployed in open environments, and hence are vulnerable to physical attacks, potentially sensor networks faces many challenges. Security is a very important issue when designing or deploying any network or protocol. In this paper we look at Data fusion process. One or several sensors then collect the detection results from other sensors. The collected data must be processed by the sensor to reduce the transmission burden before they are transmitted to the base station. This process is called data fusion. Data fusion Nodes will fuses the collected data from nearby sensor nodes before they are sent to the base station. If a fusion node is compromised, then the base station cannot ensure the correctness of the fusion data sent to it. Various methods are proposed, that deal with providing an assured data transfer to the Base Station. In this paper we present the evaluation of two methods named witnessed based and direct voting. Based on this evaluation here I proposed the new method named silent voting.
