Performance Analysis of Micro Unmanned Airborne Communication Relays for Cellular Networks

This paper analyses the potential of utilising small unmanned-aerial-vehicles (SUAV) as wireless relays for assisting cellular network performance. Whilst high altitude wireless relays have been investigated over the past 2 decades, the new class of low cost SUAVs offers new possibilities for addressing local traffic imbalances and providing emergency coverage.We present field-test results from an SUAV test-bed in both urban and rural environments. The results show that trough-to-peak throughput improvements can be achieved for users in poor coverage zones. Furthermore, the paper reinforces the experimental study with large-scale network analysis using both stochastic geometry and multi-cell simulation results.Comment: conferenc

Low energy indoor network : deployment optimisation

This article considers what the minimum energy indoor access point deployment is in order to achieve a certain downlink quality-of-service. The article investigates two conventional multiple-access technologies, namely: LTE-femtocells and 802.11n Wi-Fi. This is done in a dynamic multi-user and multi-cell interference network. Our baseline results are reinforced by novel theoretical expressions. Furthermore, the work underlines the importance of considering optimisation when accounting for the capacity saturation of realistic modulation and coding schemes. The results in this article show that optimising the location of access points both within a building and within the individual rooms is critical to minimise the energy consumption

Interpretaion of the latest development pattern of transformation from "town" into "small city" in China: a case study based on 27 pilot towns in Zhejiang Province

In the process of urbanization in China, the biggest challenge is how to transform the ‘town’ into the ‘city’. It is also a vital link in urbanization. The Chinese government put forward the strategy which aims on speeding up the urbanization development in November 2013. Meanwhile, China has selected some pilot towns, which are intended to become cities in the end, for tentative transformation. Zhejiang Province, which ranks top among the country in economic strength, amount of village and development level and quantity, has become an important national pilot carrier. So far there are 27 pilot towns. By analyzing the development situation of 27 pilot towns, this paper analyzes this particular phenomenon of urbanization and summarize its characteristics.Peer Reviewe
