摘要無線感測網路(Wireless Sensor Networks , WSNs)是由資料收集中心以及多個感測節點所組織而成,應用的領域也十分廣泛,其中所使用的無線感測節點,體積小且成本低廉,擁有許多的優點,相對地也有不少的限制,例如:電量、運算能力、儲存容量等等,而其中最直接且困難的問題在於電量的限制,若能減少一些非必要的運算或傳輸,必能減低其耗電量,進而延長網路的存活時間。 故本計劃提出一個應用於無線感測網路之網格化行動路由協定(Mobile Sink Routing Protocol with Row-prime Order Clustering in Wireless Sensor Networks , ROCP),當整個無線網路利用機器人佈置感測節點後,隨即建構出虛擬的叢集,並依此叢集建置座標系統,再透過行動式資料收集中心(Mobile Sink)直接移動至各個無線感測節點以one-hop的方式收集資料,有效地減少無線感測節點在網路上代傳封包的次數,降低電量消耗以提高整體感測網路的存活時間。 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.
