【摘要】：針對(duì)廣播通信融合網(wǎng)絡(luò)的性能分析問(wèn)題,提出了一種新的系統(tǒng)模型及能效分析方法。從用戶請(qǐng)求業(yè)務(wù)角度出發(fā),將請(qǐng)求的業(yè)務(wù)分類(lèi)為熱門(mén)與非熱門(mén)業(yè)務(wù)。并基于隨機(jī)空間網(wǎng)絡(luò)模型,將融合網(wǎng)絡(luò)中的蜂窩基站與用戶建模為2個(gè)獨(dú)立的空間泊松點(diǎn)過(guò)程(PPP)隨機(jī)分布,而廣播大塔位于服務(wù)區(qū)域中心。通過(guò)考慮廣播網(wǎng)的覆蓋范圍及蜂窩網(wǎng)的中斷概率推導(dǎo)出廣播與通信融合網(wǎng)絡(luò)下系統(tǒng)的能量效率(EE)閉合表達(dá)式,進(jìn)一步討論熱門(mén)業(yè)務(wù)概率對(duì)融合網(wǎng)絡(luò)能效的影響。仿真結(jié)果表明,基于討論的融合系統(tǒng)模型,并考慮了通用場(chǎng)景下的基站和用戶密度,當(dāng)熱門(mén)業(yè)務(wù)超過(guò)總業(yè)務(wù)的5%后,融合網(wǎng)絡(luò)能效相比于單蜂窩網(wǎng)絡(luò)有顯著提高。這種新的系統(tǒng)模型及能效分析方法為后期分析融合網(wǎng)絡(luò)總體性能奠定了基礎(chǔ)。
[Abstract]:A new system model and energy efficiency analysis method are proposed for the performance analysis of broadcast communication fusion networks. From the point of view of user request service, the requested service is classified as hot service and non hot service. Based on the stochastic spatial network model, the cellular base station and the user in the fused network are modeled as two independent spatial Poisson point processes (PPP), while the broadcast tower is located in the center of the service area. By considering the coverage of broadcast network and the outage probability of cellular network, the (EE) closed expression of energy efficiency in broadcast and communication fusion network is derived, and the influence of the probability of hot traffic on the energy efficiency of fusion network is discussed. The simulation results show that, based on the discussed fusion system model and taking into account the base station and user density in the general scenario, when the hot traffic exceeds 5% of the total services, the energy efficiency of the fusion network is significantly higher than that of the single cellular network. The new system model and energy efficiency analysis method lay the foundation for the later analysis of the overall performance of the fusion network.
