WiMAX技术在地铁应急通信组网中的应用 总被引:1,自引:0,他引:1
在地铁组网方案的选择中,在保证各项基本业务的前提下也应考虑应急情况下的通信方法。而相对于现有的2G、3G无线解决方案的点对点、点对多点、同异频组网,WIMAX技术在独享频率资源以及非视距覆盖能力上存在优势。为此,提出了利用WiMAX技术的组网方式,采用点面结合的无线覆盖方式来保证双向通信的可靠性,并且提出了频段选择、基站规划、基站设备配置等问题的解决方案。 相似文献

In 3G networks upgraded with high speed packet access (HSPA) technology, the high access bandwidth and advanced mobile devices
make it applicable to share large files among mobile users by peer-to-peer applications. To receive files as quickly as possible
is essential for mobile users in file sharing applications, since they are subject to unstable signal strength and battery
failures. While many researches present peer-to-peer file sharing architectures in mobile environments, few works focus on
decreasing the time spent in disseminating files among users. In this paper, we present an efficient peer-to-peer file sharing
design for HSPA networks called efficient file sharing (EFS) for 3G networks. EFS can decrease the dissemination time by efficiently
utilizing the upstream-bandwidth of mobile nodes. It uses an adaptive rearrangement of a node’s concurrent uploading transfers,
which causes the count of the node’s concurrent uploading transfers to lower while ensuring that the node’s upstream-bandwidth
can be efficiently utilized. Our simulations show that, EFS achieves much less dissemination time than other protocols including
Bullet Prime and a direct implementation of BitTorrent for mobile environments. 相似文献
