Development and Web Performance Evaluation of Internet of Things testbed

Internet of Things (IoT), Wireless sensor and actuator networks (WSANs) share a great mashup relation in the current communication technology trend. The number of such deployments has grown exponentially in the past few years. This growth leads the researchers to analyze, design and deploy such setups for numerous application areas ranging from simple daily life scenarios to large-scale scientific application areas. The present pace of IoT and WSAN mashup predict the interconnectivity of tens of billions of devices in the near future. Researchers are presently focused on the various aspects of IoT and WSAN mashup including basic infrastructures, heterogeneity of WSAN nodes, security aspects, data fusion etc. This paper presents a work in which an adhoc testbed has been designed to analyze various performance metrics by real experiments rather than simulations. The testbed begins with the design of basic infrastructure of WSAN nodes to gateways and its integration with the Internet, treating each WSAN node as a thing in the IoT framework. This paper describes a practical implementation of an IoT testbed as a complete framework. The testbed construction includes the design and implementation of hardware and software components of the system. Experiments have been conducted to show the results of the web performance of the testbed using different communication technologies and hardware platforms.
