Stretchable Architecture and Application-Driven Spectrum Allocation for 4G Wireless Networks

期望第四代无线（4G）网络向用户提供各种各样的多媒体服务。 然而，这些系统将在两个严格的约束下运行-有限的电池功率和有限的频谱。 该提案解决了这两个问题领域中的每一个，并描述了将增加电池寿命（每次充电传输更多比特）以及更有效地利用频谱的解决方案。 为了延长电池寿命，该提案提出了一种可扩展架构的想法，在这种架构中，耗尽的用户可以通过其他有大量剩余能量的用户建立连接。 有效管理频谱的问题与应用程序的服务质量（QoS）规范有关。 因此，应用程序控制其所需的频谱量，并显式地权衡所消耗的能量与所利用的带宽。

Fourth Generation wireless (4G) Networks are expected to provide a wide variety of multimedia services to users. However, these systems will operate under two severe constraints - limited battery power and limited spectrum. This proposal addresses each of these two problem areas and describes solution approaches that will increase the battery life (more bits transmitted per charge) as well as make a more efficient use of the spectrum. To increase battery life, the proposal presents the idea of a stretchable architecture where depleted users may set up their connections via some other user who has plenty of remaining energy. The problem of managing the spectrum efficiently is tied in with application's Quality of Service (QoS) specifications. Thus, an application controls the amount of spectrum it needs and explicitly trades off the energy consumed versus the bandwidth utilized.
