【摘要】：為了解決無線傳感器網(wǎng)絡(luò)(WSNs)的規(guī)模大、分布廣而帶寬有限與智能配電網(wǎng)對通信數(shù)據(jù)實(shí)時性和可靠性有上確界之間的矛盾,提出了一種基于最小流量的無線傳感器網(wǎng)絡(luò)路由通信模型。以無線傳感器網(wǎng)絡(luò)鏈路節(jié)點(diǎn)中接收到數(shù)據(jù)與發(fā)送出的數(shù)據(jù)之間的流量平衡為切入點(diǎn)并結(jié)合無線傳感器網(wǎng)的通信約束條件以及配電網(wǎng)數(shù)據(jù)傳輸?shù)膶?shí)時性需求,建立了基于最小流量的智能配電網(wǎng)無線傳感器網(wǎng)絡(luò)的路由通信模型。利用龐特里雅金極值的方法構(gòu)建出所設(shè)計智能配電網(wǎng)無線傳感器網(wǎng)絡(luò)通信模型的哈密爾頓函數(shù)。利用極值存在的唯一性,從必要性出發(fā)判斷出無線傳感器節(jié)點(diǎn)是否在最優(yōu)路鏈路徑上。并給出了最優(yōu)控制模型的求解過程。最后對采取所提出的通信模型的延時時間、網(wǎng)絡(luò)能量消耗、數(shù)據(jù)傳輸能力以及數(shù)據(jù)傳輸?shù)腻e誤率對比測試。結(jié)果表明,所提出的通信模型完全能夠滿足智能配電網(wǎng)通信需求。
[Abstract]:In order to solve the contradiction between the large scale, wide distribution and limited bandwidth of wireless sensor network (WSNs) and the real time and reliability of communication data in smart distribution network, This paper presents a routing communication model for wireless sensor networks based on minimum traffic. Taking the traffic balance between the received data and the transmitted data in the link node of the wireless sensor network as the breakthrough point, combining the communication constraints of the wireless sensor network and the real-time demand of the distribution network data transmission, The routing communication model of smart distribution network wireless sensor network based on minimum flow is established. The Hamiltonian function of the wireless sensor network communication model of smart distribution network is constructed by using the Ponrijagin extremum method. Based on the uniqueness of the existence of extremum, it is necessary to determine whether the wireless sensor node is in the optimal path. The process of solving the optimal control model is given. Finally, the delay time, network energy consumption, data transmission capability and error rate of the proposed communication model are compared and tested. The results show that the proposed communication model can fully meet the communication needs of smart distribution network.
