摘要

PPROBLEM TO BE SOLVED: To solve the problem that, since a radio wave status or distance between radio sensor nodes is not considered conventionally, a route can not be stably constructed, a frame of the same contents flows on a network over and over again during data collection, and entire throughput is considerably reduced. PSOLUTION: A base station node 5 comprises a route constructing means 55, a data collecting means 56, and a route re-constructing means 57. The route constructing means 55 constructs a stable route in a tree shape based on location information of radio sensor nodes 3 and their mutual radio wave strengths and divides the route into groups. The data collecting means 56 collects data for the unit of each of radio sensor nodes divided into groups and acquires sensor data from a group master radio sensor node 4. If the radio wave status between radio sensor nodes is adverse and data collection is failed, the route re-constructing means 57 does not reconstruct the route immediately and if the data collection is failed over M times, it is shifted to processing of the route re-constructing means 57.

要解決的問題：為了解決以下問題：由于常規(guī)上不考慮無線電波的狀態(tài)或無線電傳感器節(jié)點(diǎn)之間的距離，因此無法穩(wěn)定地構(gòu)建路由，因此，具有相同內(nèi)容的幀在網(wǎng)絡(luò)上流過，并且再次在數(shù)據(jù)收集過程中，整個(gè)吞吐量顯著降低。解決方案：基站節(jié)點(diǎn)5包括路線構(gòu)造裝置55，數(shù)據(jù)收集裝置56和路線重新構(gòu)造裝置57。路線構(gòu)造裝置55基于樹的位置信息構(gòu)造樹狀的穩(wěn)定路線。無線電傳感器節(jié)點(diǎn)3及其相互的無線電波強(qiáng)度并將路由分為幾組。數(shù)據(jù)收集裝置56收集被分成組的每個(gè)無線電傳感器節(jié)點(diǎn)的單位的數(shù)據(jù)，并從組主無線電傳感器節(jié)點(diǎn)4獲取傳感器數(shù)據(jù)。如果無線電傳感器節(jié)點(diǎn)之間的無線電波狀態(tài)不利并且數(shù)據(jù)收集失敗，則路線重構(gòu)裝置57不立即重構(gòu)路線，并且如果數(shù)據(jù)收集失敗了M次，則轉(zhuǎn)移到路線重構(gòu)裝置57的處理。
