In this paper, the WISCA Software Defined Radio (SDR) Network platform are presented. The WISCA SDR Network provides the user with a highly configurable and flexible algorithm development platform to conduct wireless communication research. Each node in the network utilizes Ettus Research USRP (Universal Software Radio Peripheral) technology for the radio frequency front end, along with the industry standard MATLAB algorithm development environment for baseband processing. As a result, the WISCA SDR network allows the user to develop and test new concepts quickly. It demonstrates the flexibility of this system by providing a couple of examples involving message forwarding, carrier sensing and a joint radar-communications system. To help improve and further develop the system, the WISCA SDR Network will be released as an open source project.
