Quality of service in wireless sensor networks through a failure-detector with voting mechanism

Many anomalies can be viewed in Wireless Sensor Network e.g. abnormal behavior, unreliable link or sensor, low energy. In this paper, a sensors´ failure detector by voting system based on captured data is proposed. Our motivation is to alleviate network´s charge by eliminating useless sensors. Also, we look for making the network more sure and confident. This is expressed by the quality of service (Qos) that is presented with confidence and exactitude measures. As the both performances are mostly more than 75%, testing results are interesting to increase the Qos. To calculate these, we have employed a various types of errors such as Byzantine, temporary, latent and others.
