1. PROWIND (Positioning Relay over Wirelessly Networked Devices) Team Members: Mark Buising, Douglas Chow, Nazeni Mkrtchyan, Jesus Rodriguez, Jennifer Webb Faculty Advisor: Dr. Russell Abbott Aerospace Corporation Liaison: Mahan Hajianpour, Zaven Petrosyan Department of Computer Science College of Engineering, Computer Science, and Technology California State University, Los Angeles PROWIND is an Android messaging, mapping, and tracking application that integrates location information in the creation of the mesh topology in an ad hoc wireless network. The mesh infrastructure allows multi-hop communication among devices, a functionality usually lacking in ad hoc wireless networks due to the need for existing wireless access points and routers. However, wireless mesh networking is still a growing research field, and very few stable implementations exist for mobile device platforms, such as the Android operating system. The nature of this project was to find a feasible wireless infrastructure that can be used to demonstrate the relay of location information among devices.
