| Summary: | 碩士 === 淡江大學 === 資訊工程學系資訊網路與通訊碩士班 === 96 === Wireless Sensor Networks (WSNs) are composed of sink node and multiple sensor nodes. The wireless sensor exists several advantages, such as compact size and low cost. Relatively, there are some limitations, including power, computing ability and storage capacity etc. The greatest challenge among all is the constraints on energy. If we can decrease some unnecessary computations and transportations, so that the power consumption is reduced and the life time of whole network will be prolonged.
Therefore, we propose a sequence moving scheme which utilizes concept of cluster-based network with mobile sink, called “Mobile Sink Routing Protocol with Row-prime Order Clustering in Wireless Sensor Networks”(ROCP), at an attempt to resolve the above issue. We perform the clustering process with row-prime order and bring the coordinates system after we dispose sensor nodes by robot. And then the mobile sink move to each cluster directly by a specific routing algorithm and gather sensing data by one-hop routing. Thus, we reduce the frequency of packet forwarding to sink and prolong the life time of whole sensor network in our proposal.
