It is well documented how cooperative links can offer considerable performance gains at the physical layer, but it is unclear what kind of network support would be required to attain the sought gains. Cooperative links violate the simple collision model for broadcast transmission, a model that has been instrumental so far in allowing the parallel evolution of communication theory and network theory. Recognizing the absence of a correct taxonomy to use cooperative links at the network and multiple access layer, the objective of this collaborative project is to investigate theoretically and experimentally the interplay between a cooperative decentralized physical layer and the wireless network architecture as a whole. More specifically, the project will develop viable link abstractions, multiple access protocols, end-to-end network transport models, appropriate algorithms to support the introduction in wireless mobile networks of two technologies that are rapidly advancing: 1) cooperative transmission, that consists of multiple network nodes operating as a decentralized multi-antenna modem and, 2) distributed source coding, that allows the decentralized compression of correlated observations and, thus, is relevant to the design of a decentralized receiver.The project will also use the GNU software radio platform to test cooperative links and assess their feasibility and degradation when facing real limitations of transceiver synchronization, carrier offset, clock jitter and computation delays. Algorithms and theoretical results will be disseminated through the standard tools of research publications. Experimental results will be also documented online where the software will be shared to serve as an educational tool as well as to foster new technological advances in mesh networks.This project will bring future wireless networks closer to achieving the physical limits of communications.

有充分记录的合作链接如何在物理层提供可观的性能提高，但是目前尚不清楚获得哪种网络支持才能获得所寻求的收益。 合作链接违反了用于广播传输的简单碰撞模型，该模型迄今已在允许传播理论和网络理论的并行演变方面具有重要作用。认识到缺乏正确的分类法无法在网络和多个访问层上使用合作链接，因此该协作项目的目的是在理论上和实验上研究合作分散的物理层与整个无线网络体系结构之间的相互作用。更具体地说，该项目将开发可行的链接摘要，多个访问协议，端到端网络传输模型，适当的算法，以支持两种快速前进的技术的无线移动网络中的介绍：1）合作传输，合成多个网络节点，由多个网络节点作为运行的多个网络节点，从而允许分散的多端antenna调制解器和2）分散分散的分散分散的源代码，并将该项目还将使用GNU软件无线电平台来测试合作链接并评估其可行性和退化，当面对收发器同步，运营商偏移，时钟抖动和计算延迟时，该项目还将评估其可行性和退化。算法和理论结果将通过研究出版物的标准工具传播。实验结果还将在线记录在线记录，该软件将作为一种教育工具共享，并促进网络网络中的新技术进步。该项目将使未来的无线网络更接近实现通信的物理限制。
