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

无线网状网络因其无处不在的低成本无线宽带连接而变得越来越流行。然而，它们遭受严重的干扰问题，限制了它们的能力。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，以及各种形式的多样性-例如发射功率控制，定向天线，多通道和速率-以最大限度地提高性能。我们还介绍了一种基于测量的建模技术，使物理干涉建模变得可行。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、协议和针对“托管”网状网络的系统解决方案。协议解决方案包括路由层及以下，并与现有的传输层及以上的网络间协议兼容。该项目的智力优势有以下组成部分：(i)具有多样性和物理干扰建模的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，以及（iv）仿真建模和试验台实验以支持协议创新。该项目有助于两所大学（佐治亚理工学院和石溪大学）研究生的教育和培训。该项目利用了pi与意大利IIT-CNR和印度CDAC的现有国际合作，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。它可以很好地与无线局域网和有线连接竞争，并有望在技术竞争中保持平衡。

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.
