文档介绍：Mesh实现调研报告
单位1:Laboratory for munications Sciences US Department of Defense
实现场景:大型,户外,仿真
使用器材:移去RF的node节点,使用cable相连
特点:省去RF层复杂的考虑,可以作为我们设计时的一种思想(mesh路由器需要由连线->无线的过渡)

MeshTest: Laboratory-Based Wireless Testbed for Large Topologies
该论文提出了仿真平台的共性:
mesh仿真平台共性
Cost:
the price per node of the wireless testbed should be relatively low for wide-scale deployments.
Management:
nodes should be easily managed from a single location via some out-of-band control channel such as an independent interface.
Resource Sharing:
the testbed should be usable by multiple users simultaneously if enough nodes are available to modate their simulations.
Experimental Control:
the testbed should allow for the automatic configuration of the experiment topology, applications, node mobility, device configuration, execution, and debugging.
Experimental Analysis:
analysis tools should be available to filter, visualize, and extract statistics from collected traces.
Applicability:
the testbed should support testing and evaluation of diverse protocol suites, both at the application layers and PHY/MAC layers.
Repeatability:
experiment executions should produce repeatable results.
单位2:University of Leipzig department puter Science (Leipzig, Germany)
实现场景:未指定(我认为是室外)
使用器材:(后面有详述)
variable attenuators 调节传输范围
Linux system
特点:
使用小型化的天线和传输技术来模拟大型化的区域传输(这个有点假)
论文中给出仿真结果和原型相差不大,可以作为布网前的模拟

ScaleMesh: A Scalable Dual-Radio Wireless Mesh Testbed
Each node consists of a Siemens ESPRIMO P2510 PC with an Intel Celeron GHz processor and two IEEE WG311T wireless work interface cards (NICs) with Atheros chipsets. Each wireless card is connected to a variable signal attenuator and a low-gain antenna.
The variable attenuators are connected to the wireless PCI cards through 50 Ohm, 7m long, highly shielded aircell5 coaxial cables, whereas the antennas are connected to the signal attenuators through a 50 Ohm, 3m long RG-174 coaxial cable.
