在无线通信网络中引入移动性以改善性能

Performance Improvement by Introducing Mobility in Wireless Communication Networks

Hailong Huang

摘要:

通信技术是我们生活方式的主要贡献者。提高通信系统的性能给人类带来了多方面的好处。本报告涵盖了两个典型的这样的系统:无线传感器网络和蜂窝网络。我们研究了这些网络中的流动性的影响。在无线传感器网络中,我们考虑使用移动汇从静态节点收集传感器数据。对于后一种情况,我们设计了数据汇集协议,为一个单一的移动sink,旨在平衡传感器节点之间的能量消耗,以提高网络的生命周期。我们还设计了一个算法,多个移动汇收集紧急的感官信息在允许的延迟。关于蜂窝网络中的移动性,我们的意思是服务提供商是移动的。传统的方法通常考虑如何根据诸如吞吐量的特定度量来最优地部署静态基站。基站密集化是一种解决方案,但它不具有成本效益。引入移动性是为了让基站在天上飞,从而减少投资。我们考虑使用无人机为蜂窝用户服务的关键问题之一:无人机部署。我们已经实现了所有提出的算法,无论是模拟或实验,结果证实了这些方法的有效性。

英文摘要:

Communication technology is a major contributor to our lifestyles. Improving the performance of communication system brings with various benefits to human beings. This report covers two typical such systems: wireless sensor networks and cellular networks. We study the influence of mobility in these networks. In wireless sensor networks, we consider the usage of mobile sinks to collect sensory data from static nodes. For the latter case, we design data collection protocols for a single mobile sink which aim at balancing the energy consumption among sensor nodes to improve the network lifetime. We also design an algorithm for multiple mobile sinks to collect urgent sensory information within the allowed latency. Regarding the mobility in cellular networks, we mean the service providers are mobile. Conventional approaches usually consider how to optimally deploy static base stations according to a certain metric, such as throughput. Base station densification is a solution, but it is not cost efficient. Introducing mobility is to let the base stations fly in the sky, resulting in less investment. We consider one of the key issues of using drones to serve cellular users: drone deployment. We have implemented all the proposed algorithms by either simulations or experiments, and the results have confirmed the effectiveness of these approaches.
