BRIGE: Cross-layer Inter-network Cooperation for Broadcast, Cellular and Ad-hoc Hybrid System

智力价值：合作本质上是一种有效的战略，通过形成合作小组来实现个人或共同目标。虽然无线通信研究界已经证明，协作技术可以显著提高系统性能，但现有的大部分工作仅限于单个网络。另一方面，无处不在的无线应用带来了越来越多的新网络，使得多网络共存成为必然。Brige研究的目标是利用跨层网络间协作技术开发一种新的网络结构，将蜂窝网络、电视广播网络和自组织网络集成在一起。该项目的研究部分由两部分组成。第一部分是协同广播和蜂窝混合系统，这是一种在单一平台上同时支持广播和蜂窝服务的联合设计方法。在这个项目中，重点放在更实用的联合编码混合模型上，其中信息比特在时间和频率上进行编码。第二部分是协作蜂窝和自组织混合系统，它实现了基础设施网络(高吞吐量、良好的可靠性和服务质量)和自组织网络(覆盖范围更大、成本更低、灵活性更高)所提供的好处。广泛的影响：该项目中确定的问题是内在认识的，因此研究成果可能会影响和改变科学和技术趋势，而不是跟随。特别是，拟议的混合网络结构将为难以到达、人口密度较低的地区带来新的无线服务，这些地区是农村环境的典型。PI还将招募北达科他州代表性不足的群体的学生，包括美洲原住民、女性、低收入学生和第一代学生参与该项目。通过将研究和教育结合在一起，该项目将扩大未被充分代表的群体在工程学领域的参与。

Intellectual Merit: Cooperation is an effective strategy in nature to achieve individual or common goals by forming cooperative groups. While the wireless communications research community has shown that cooperation techniques can substantially increase the system performance, most of the existing work is limited to a single network. On the other hand, the ubiquitous wireless applications are bringing more and more new networks, making the co-existence of multi-networks inevitable. The objective of this BRIGE research is to develop a new network structure that integrates cellular, TV broadcast, and ad-hoc networks using cross-layer inter-network cooperation techniques. The research components of the project consist of two parts. The first part is a collaborative broadcast and cellular hybrid system, which is a joint design approach for broadcast and cellular services to be simultaneously supported in a single platform. In this project, focus is on the more practical hybrid model with joint coding, where information bits are coded across both time and frequency. The second part is a collaborative cellular and ad-hoc hybrid system, which achieves the benefits offered by both infrastructure networks (high throughput, good reliability and quality of service) and ad-hoc networks (larger coverage, low cost and flexibility).Broader Impacts: The issues identified in this project are inherently cognizant, thus the research output will likely influence and transform, rather than follow, scientific and technological trends. In particular, the proposed hybrid network structure will bring new wireless services to hard-to-reach, low population density areas, typical of rural environments. The PI will also recruit students of underrepresented groups in North Dakota, including Native American, female, low incoming and first generation students to participate in the project. By integrating research and education together, this project will broaden the participation of underrepresented groups in engineering.
