| Summary: | 碩士 === 淡江大學 === 資訊工程學系資訊網路與通訊碩士班 === 102 === Simply ZigBee is a short-range, low transmission rate, receive a small amount of data, low power consumption, easy provisioning of wireless network transmission technology. because of its multi-point communications cause communication burden, thus the need for efficient use of limited power. Dynamic source routing(DSR) designed primarily to be able to prolong the survival time of the whole sensor nodes, perform Route Maintenance process occurs when the Route Error, Route Cache is used to select a path that may occur selected to Stale Route, causing Route breakage, so in order to solve this issue needs to effectively distinguish Stale Route and fresh route.
In this thesis, we propose use Markov chain, the buffer, packet loss, transmission out of range ,three parameters to prediction the time out of their nodes. Achieve effective management of Route Cache, can effectively reduce packet loss, End to End Delay and improved DSR performance.
