【摘要】：隨著物聯(lián)網(wǎng)技術(shù)的不斷發(fā)展、物聯(lián)網(wǎng)應(yīng)用的逐漸推廣,單一的接入網(wǎng)絡(luò)很難滿足全部的物聯(lián)網(wǎng)業(yè)務(wù)需求,多網(wǎng)并存、融合成為物聯(lián)網(wǎng)發(fā)展的主流方向。為了保證物聯(lián)網(wǎng)終端的運行,如何建立高效的資源分配策略是需要解決的首要問題。提出了1種基于用戶滿意度的異構(gòu)物聯(lián)網(wǎng)資源分配策略。在綜合考慮用戶體驗和傳輸速率的基礎(chǔ)上,得到優(yōu)化的效用函數(shù),通過計算物聯(lián)網(wǎng)終端在不同接入網(wǎng)中的最優(yōu)帶寬,得到有效的異構(gòu)物聯(lián)網(wǎng)網(wǎng)絡(luò)資源分配算法。仿真分析結(jié)果表明,所描述的資源分配算法相比其他算法可以獲得更好的用戶滿意度。
[Abstract]:With the continuous development of Internet of things technology and the gradual promotion of the application of the Internet of things, it is difficult for a single access network to meet all the business needs of the Internet of things. Multiple networks coexist, and integration has become the mainstream direction of the development of the Internet of things. In order to ensure the operation of Internet of things terminal, how to establish an efficient resource allocation strategy is the first problem to be solved. A heterogeneous Internet of things resource allocation strategy based on user satisfaction is proposed. Based on the comprehensive consideration of user experience and transmission rate, the optimized utility function is obtained. By calculating the optimal bandwidth of Internet of things terminals in different access networks, an effective heterogeneous Internet of things network resource allocation algorithm is obtained. The simulation results show that the described resource allocation algorithm can obtain better user satisfaction than other algorithms.
