Researchers Seek

Wireless-Test Nirvana

Fueled by a four-year grant from the National Science Foundation

(NSF), researchers from Rutgers

University (East Brunswick, NJ) are addressing the myriad of existing and emerging wireless protocols and designs with the development of a large, comprehensive wireless-network testbed. The system's goal is to accommodate and attract innovative experimental research on next-generation protocols and applications.

Initialized in 2003, the study
