| Summary: | 碩士 === 國立澎湖科技大學 === 電資研究所 === 103 === Current domestic and foreign, only for underwater wireless sensor networks or natural energy power wireless sensor networks have mentioned network signal enhancement or clustering calculus network protocol but did not propose the best of the difference between stability and non-stability. Therefore, this article use all of the nodes to send messages between stability and non-stability, if the base station is broken or faulty it can find another base station instantly and the communications will link again. Suppose the researchers link it in the shortest path at the base station, it will continue using the network to communicate, but the base station life will be shortened. If the researchers use multi-path node to connect communication in the base station line, it will has enough time to rest for each base station, and the node's failure rate will be dropped significantly.
Our Earth covers about two-thirds of the surface in ocean and has fascinated humans for as long as people have kept records. The Penghu Islands are an archipelago off the western coast of Taiwan in the Taiwan Strait. The Penghu islands have extensive marine resources and fishing techniques and the traditional set-net catch technology is proud. However, for underwater explorations are used to explore large uninhibited oceans, each underwater acoustic link features large-latency and low bandwidth, this paper will use it to explore the fishing technology of Penghu set net. This method is reasonable and accurate to collect the information about tidal data and actual catches. For the set-net fishing, the researchers use the wireless sensor networks and underwater acoustic networks.
This article will use the grid theory developed into a network structure. Through the underwater wireless sensor networks real time with catches and corresponding to the information of tide, the researchers get the tidal catches data. These data will be standardized and determine their correlation coefficients. Finally, though the grey relational algorithm to find the grey relational degree between the tides and catches. Via this article, not only to enrich the technology of Penghu set net, and also further explore the technology application level on underwater sensing networks.
