“…Attenuators and RF switches can be used to form topologies and emulate distance between nodes. MeshTest [18] is one example of such set up with a design close to our work. However, their method requires complex design for higher number of nodes.…”

Abstract. As wireless networks become a critical part of home, business and industrial infrastructure, researchers will meet these demands by providing new networking technologies. However, these technologies must be tested before they can be released for mainstream use. We identify the key design considerations for a wireless networking testbed as a) accuracy b) controllability c) mobility d) repeatability e) cost effectiveness f) data collection g) resource sharing h) multi-nodal capability i) scalability. In this paper we portray how we have used coaxial cables and our custom hardware of RF switches and programmable attenuators to create Advanced wireleSS Environment Research Testbed (assert), addressing the above requirements. assert supports various types of wireless devices, providing researchers in academia and industry with the necessary experimentation tools to validate their designed protocols and devices.

“…This placement is usually according to a regular geometry, such as a grid as used in ORBIT (Raychaudhuri et al 2005) or Kansei (Arora et al 2006). Such testbeds are typically equipped with some form of attenuator as in EWANT (Sanghani et al 2003), MiNT , and MeshTest (Clancy and Walker 2007), and they may have their signals routed through an antenna or connected through a hardwired matrix such as in MeshTest (Clancy and Walker 2007). However, by definition, the miniaturized testbed does not provide realistic multi-path, for instance, efforts such in (Judd and Steenkiste 2004) utilize an FPGA based solution for emulating a signal propagation model, which are still far from reality ).…”

“…In the category of miniaturized testbeds are MiNT ), MiNT-m (De et al 2006), and MeshTest (Clancy and Walker 2007). MeshTest is particularly interesting because of its ability to control interference and attenuation while supporting mobility and providing users with control over topology.…”

Simulation is imagining … Testbed is sore reality. WSN Testbeds PrinciplesAs iterated throughout this book, WSNs are large-scale distributed embedded systems incorporating small, limited energy, and resource constrained sensor nodes communicating over wireless media. Because of their massively distributed nature, the design, implementation and evaluation of sensor network applications, middleware and communication protocols are difficult tasks. The first design steps can often be made with the help of simulations; however, they frequently force the designer to make non-realistic assumptions about traffic, failure patterns and topologies. The coming after steps of implementation, and evaluation of application performance, as well as assessment of error resilience, and other nonfunctional properties, require the use of real hardware, realistic environments and realistic experimental setups.Practically, real experiments with distributed systems like WSNs become very cumbersome if the number of nodes exceeds a few dozens. In fact, all the phases of the experiment are almost infeasible without a targeted, specialized support, specifically:

“…The first includes a deployment of nodes in a realistic environment with physical antennas and channel modifiers such as noise generators (ORBIT [1], and EWANT [2]). The other applies channel emulation using active components such as programmable signal attenuators (MeshTest [3]), and signal processing boards such as an FPGA (CMU Wireless Emulator [4]). The first approach may face problems with isolation and interference as these parameters are not completely controlled by the testbed.…”
