NeTS-WN: Collaborative Research: A Measurement-Driven Physical-Interference-Based Approach for the Design of Mesh Networks

无线Mesh网络因其无处不在的低成本无线宽带连接而变得流行起来。然而，它们受到严重的干扰问题，限制了它们的容量。我们使用TDMA调度来解决这些性能问题。我们使用基于SINR的物理干扰建模来实现真实感，并使用各种形式的多样性-例如发射功率控制、定向天线、多个通道和速率-来最大化性能。我们还引入了一种基于测量的建模技术，使物理干扰建模变得实用。我们通过实验研究来支持这些创新。我们的目标是开发一套完整的算法、协议和系统解决方案，以“管理的”网状网络为目标。该项目的智能优势包括：(I)具有分集和物理干扰建模的TDMA调度新协议；(Ii)调度与路由的集成；(Iii)基于测量的物理干扰建模；(Iv)支持协议创新的仿真建模和试验台实验。该项目为佐治亚理工学院和石溪大学两所大学的研究生教育和培训做出了贡献。该项目从现有的与意大利的IIT-CNR和印度的CDAC的PIS的国际合作中获益，并加强了这种合作。最后，这个项目的成功意味着低成本、无处不在的宽带连接。它在与无线局域网和有线连接的竞争中表现出色，预计将为技术竞争创造公平的环境。

Wireless mesh networks are becoming popular for ubiquitous and low-cost wireless broadband connectivity. However, they, suffer from serious interference problems which limit their capacity. We use TDMA scheduling to address these performance problems. We use a SINR-based physical interference modeling for realism, and various forms of diversities - such as transmit power control, directional antennas, multiple channels, and rates - to maximize performance. We also introduce a measurement-based modeling technique to make the physical interference modeling practical. We support these innovations by experimental studies. Our goal is developing a complete set of algorithms, protocols, and system solutions that target "managed" mesh networks. The protocol solutions include the routing layer and below, and are compatible with existing Inter-networking protocols for the transport layer and up.The project's intellectual merit has the following components: (i) New protocols for TDMA scheduling with diversity and physical interference modeling, (ii) integration of scheduling with routing, (iii) measurement-based modeling of physical interference, and (iv) simulation modeling and testbed experiments to support the protocol innovations.The project contributes to the education and training of graduate students in the two universities -Georgia Tech and Stony Brook University. The project gains leverage from existing international collaborations of PIs with IIT-CNR in Italy and CDAC in India, and strengthens this collaboration. Finally, success in this project means low cost, ubiquitous broadband connectivity. It competes well with WLANs and wired connectivity, and is expected to level the technological playing field.
