【摘要】：提出了一種基于流內(nèi)與流間網(wǎng)絡(luò)編碼的延遲容忍移動(dòng)傳感器網(wǎng)絡(luò)(DTMSN)高效廣播傳輸機(jī)制.在該機(jī)制中,匯聚節(jié)點(diǎn)利用隨機(jī)線性網(wǎng)絡(luò)編碼將原始數(shù)據(jù)處理成編碼包,然后轉(zhuǎn)發(fā)給傳感器節(jié)點(diǎn).傳感器節(jié)點(diǎn)間利用一種優(yōu)化的機(jī)會(huì)網(wǎng)絡(luò)編碼算法交換編碼包.當(dāng)傳感器節(jié)點(diǎn)收到足夠多的線性無關(guān)編碼包時(shí)解碼得到原始廣播數(shù)據(jù).理論分析和仿真實(shí)驗(yàn)表明,與僅基于隨機(jī)線性網(wǎng)絡(luò)編碼的廣播傳輸機(jī)制相比,該機(jī)制能進(jìn)一步減小廣播時(shí)延和網(wǎng)絡(luò)負(fù)載.
[Abstract]:An efficient broadcast transmission mechanism for delay tolerant mobile sensor networks (DTMSN) based on intra-stream and inter-stream network coding is proposed. In this mechanism, the convergent node processes the raw data into coding packets using random linear network coding and forwards them to the sensor node. Sensor nodes exchange packets using an optimized opportunistic network coding algorithm. The original broadcast data is decoded when the sensor node receives enough linearly independent coding packets. Theoretical analysis and simulation experiments show that the proposed scheme can further reduce the broadcast delay and network load compared with the broadcast transmission mechanism based on stochastic linear network coding only.
