【摘要】：為實(shí)現(xiàn)溫室大棚的智能化和實(shí)時(shí)監(jiān)測(cè)的目的,結(jié)合ZigBee技術(shù),設(shè)計(jì)了一種基于ZigBee技術(shù)的溫室大棚遠(yuǎn)程監(jiān)測(cè)方案。由于ZigBee樹型路由算法存在路徑選擇不優(yōu)的問題,進(jìn)一步提出一種適用于溫室大棚實(shí)時(shí)監(jiān)測(cè)系統(tǒng)的ZigBee路由優(yōu)化算法。該算法并不特定選擇下一跳節(jié)點(diǎn),而是根據(jù)一跳范圍內(nèi)鄰居節(jié)點(diǎn)到目的節(jié)點(diǎn)的剩余跳數(shù)這一優(yōu)先權(quán)來限制剩余跳數(shù)較多的鄰居節(jié)點(diǎn)作為被選節(jié)點(diǎn),從而降低節(jié)點(diǎn)轉(zhuǎn)發(fā)跳數(shù),提高系統(tǒng)的實(shí)時(shí)性。多次仿真結(jié)果表明,改進(jìn)算法在節(jié)點(diǎn)跳數(shù)、端到端的延時(shí)及可靠性方面均有一定程度的改善。
[Abstract]:In order to realize the purpose of intelligent and real-time monitoring of greenhouse, a remote monitoring scheme of greenhouse based on ZigBee technology was designed based on ZigBee technology. Due to the problem of poor path selection in ZigBee tree routing algorithm, a ZigBee routing optimization algorithm for greenhouse real-time monitoring system is proposed. The algorithm does not specifically select the next hop node, but according to the priority of the neighbor node to the destination node in one hop range, it limits the neighbor node with more remaining hops as the selected node, thus reducing the number of forwarding hops. Improve the real-time performance of the system. The simulation results show that the improved algorithm can improve node hops, end-to-end delay and reliability to some extent.
