Small (10kg) UAVs are low-cost low-risk candidates for emerging UAV applications. Examples include multi-UAV swarming, flocking, and sensing operations; or, as a communication relay for a network of ground radios mounted at fixed sites, on vehicles, or in sensors. A key enabler is the ability of the UAVs to communicate with each other and with ground based radios as a distributed peer-to-peer ad hoc network. Such networks allow any two radio nodes to communicate directly or through an arbitrary number of intermediate nodes which act as relays. Thus, understanding the performance of such networks in these UAV scenarios is necessary to understand the limits of multi-UAV operations. The University of Colorado has developed and built a wireless network test bed using IEEE 802.11b (WiFi) radio equipment mounted on small low-cost UAVs. This paper describes the testbed and its monitoring architecture. The testbed gives detailed data on network throughput, delay, range, and connectivity under different operating regimes. These results enable us to better document and characterize real ad hoc network behavior among UAVs.
More and more researchers want to use games as a way of engaging the general public in their research; however game development takes time and requires significant programming knowledge. The goal of RedWire is to enable researchers to create games faster without starting from scratch each time. By encouraging re-mixing and mash-ups, we hope to provide users with an easy way of sharing games and creating variations of games.
Video game developers make heavy use of "metrics" (or "analytics") in order to understand the players' actions. This serves to improve the games by identifying weaknesses in their design, such as sections of the games that are too difficult, or never explored. While such data may be of great interest to scientists and the public at large, it is rarely, if ever, publicly available.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
