Switching and Routing for All Wireless Multi-Beam Ad-Hoc Networks

使用多波束天线阵列进行传输和接收允许无线单元在不同方向上使用多个频带发送和接收数十个波束。如果我们在大面积上部署大量这样的多波束无线单元，我们将获得高度连接和高容量的无线网络。我们称之为全无线网络（AWN）。 类似于全光网络中的密集波分复用技术，我们提出了一种类似于全无线网络中的频分和空分复用技术。与AON的点对点连接不同，我们认为来自无线多波束单元的具有灵活分配的方向和频率的大量并行数量的波束可以提供无限的连接和带宽。我们依靠空间并行性来实现极高的网络吞吐量。 AWN可以被布置为空间分布的多级电路交换机或完全连接的环，从而允许并行和空间分布的交换结构的多速率和多播能力。单个多波束无线单元可以从多个波束接收，以实现应用的每秒千兆吞吐量。无线单元还可以作为中继节点，通过交换结构将给定方向和频率的输入波束切换到不同方向和频率的输出波束上。这类似于AON中DWDM的全光交换，除了我们增加了自由和连续空间连接的维度，而不是光纤到光纤的连接。 我们将设计交换和路由理论和技术的SD/FD电路交换AWN，考虑到同信道和相邻信道的干扰和各种衰落因素。我们formulatemetric的路由，占功耗，覆盖的距离，和外部性引起的其他路线。我们研究了此类路由技术的社会最优性与个人最优性。 使用OPNET软件包，我们将实现AWN的仿真。针对每个无线多波束单元对所发射的辐射图案进行建模。我们在一个区域分布许多这样的单位，随机或使用各种无线互连网络拓扑结构。传播障碍也被建模。图形仿真提供功率和干扰电平的估计。各种功率控制和路由协议将使用仿真软件进行测试。 理论和仿真结果将被用来设计一个互联网电路（IC）路由器。路由和交换算法将采用分布式方式，通过使用链路状态路由表或使用源发起的连接请求建立多路径连接。我们计划实施一个简单的IC路由器，用于无线多波束单元的互连，以进行概念演示。 我们相信，所提出的AWN架构应是低成本，高性能，和高度灵活的业务模式和链路/节点损伤。AWN的高吞吐量将允许完全通过无线通信按需提供高质量的多媒体应用。

The use of multi-beam antenna arrays for transmission and reception allows wireless units to send andreceive tens of beams in different directions and using multiple frequency bands. If we deploy a large numberof such multi-beam wireless units over a large area, we obtain a highly connected and high capacity wirelessnetwork. We call this the All Wireless Network (AWN). Analogous to Dense Wavelength Division Multiplexing (DWDM) in All Optical Networks (AON), wepropose an analogous Frequency Division (FD) and Space Division (SD) technique for All WirelessNetworks (AWN). Unlike point-to-point connectivity of an AON, we argue that massively parallel number ofbeams with flexibly assigned direction and frequency from wireless multi-beam units can provide unlimitedconnectivity and bandwidth. We rely on spatial parallelism to achieve an extremely high network throughput. An AWN can be arranged as a spatially distributed multi-stage circuit switch or a fully connected ring,allowing multi-rate and multi-cast capability of a parallel and spatially distributed switch fabric. A singlemulti-beam wireless unit can receive from multiple beams to achieve a Gigabit per second throughput for anapplication. The wireless unit can also serve as relay nodes to switch incoming beams of given direction andfrequency through a switch fabric onto outgoing beams of different direction and frequency. This is analogousto all optical switching for DWDM in an AON, except we have an added dimension of free and continuousspatial connectivity, rather than fiber-to-fiber connectivity. We shall devise switching and routing theory and techniques for SD/FD circuit switching over AWN,taking into account co-channel and adjacent channel interference and various fading factors. We formulatemetric for routing that accounts for power consumption, distance covered, and externality induced to otherroutes. We study social optimality versus individual optimality for such routing techniques. Using the OPNET software package, we shall implement a simulation of the AWN. The transmittedradiation pattern is modeled for each wireless multi-beam unit. We distribute many such units over an area,either randomly or using various wireless interconnection network topologies. Propagation barriers are alsomodeled. The graphical simulation provides estimation of power and interference level. Various power controland routing protocols will be tested using the simulation software. Theoretical and simulation results will be used to design an Internet Circuit (IC) Router. Routing andswitching algorithms will be made distributed with a multiple -path connection set-up using a link state routing table, or using source initiated connection requests. We plan to implement a simple IC Router for theinternetworking of wireless multi-beam units for concept demonstration. We believe that the proposed AWN architecture shall be low cost, high performance, and highly flexiblefor traffic pattern and link/node impairments. The high throughput of the AWN will allow high qualitymultimedia applications to be delivered on-demand entirely by wireless communications.
