| Summary: | 碩士 === 國立成功大學 === 資訊工程學系碩博士班 === 93 === In wireless sensor network environment, we may run many applications, such as environmental monitoring and traffic control, etc. Most of the applications require sensor network to report data to users. But data loss is very likely to occur when we transmit data in sensor network via ad-hoc routing protocols.To avoid data loss, we introduced a redundancy method. We also developed a accuracy evaluation function and routing strategy to further enhance the ability to deal with data loss. Depend on the importance of data, we may use different ratio of redundancy to deal with data loss.In the end of the thesis, through experiments we proved that our accuracy evaluation function is quite helpful for users and the routing strategy do further enhance the ability to deal with data loss.
