Gustavo Vejarano is an Assistant Professor in the Department of Electrical Engineering and Computer Science and director of the Intemnets Laboratory at Loyola Marymount University. He earned his B.S. in electrical engineering at Universidad del Valle, Cali, Colombia in 2005 and his M.S. and Ph.D. in electrical and computer engineering at the University of Florida, Gainesville, FL in 2009 and 2011 respectively. In 2006, he worked for ZTE Corporation as engineer for the deployment of a city-wide cellular network. During his Ph.D., he conducted research on wireless communication networks at the Wireless and Mobile Systems Laboratory. The results of his research have been published in the IEEE Transactions on Parallel and Distributed Systems, the Elsevier Computer Networks Journal, and several international conferences. His research was also applied in the development of multimedia communication technologies at the US Army’s Communications-Electronics Research, Development, and Engineering Center, where he participated in the design, implementation, and evaluation of video and audio communication systems. In higher education, Gustavo has worked on the development of constructivist learning techniques for undergraduate students of electrical engineering. His work has been published in the IEEE Transactions on Education. He has been a mentor of the McNair Scholars, NASA-MUST, and NSF-SEAGEP programs, which provide career guidance to undergraduate students in the science, technology, engineering, and math (STEM) disciplines.

Projects/Simulators

WIMU Motion Capture (Dai Meng and Gustavo Vejarano, 2013)
WIMU Motion Capture is a system that measures joint angles of the human body using a wireless sensor network of Shimmer IMU nodes. The principle of operation is based on measurements of the alignments of the different limb segments with the earth's gravity and magnetic fields.

WiMAX-RBDS-Sim (Gustavo Vejarano and Janise McNair, 2010)
WiMAX-RBDS-Sim is a simulation model for IEEE 802.16 (WiMAX) wireless mesh networks with distributed scheduling for the OPNET Modeler. It provides a framework for the evaluation of reservation-based distributed scheduling (RBDS) policies at the medium access control (MAC) layer. It provides interfaces for the integration of RBDS policies and link-establishment algorithms.

cdma2000-UV Simulator (Gustavo Vejarano and Fabio Guerrero, 2005)
The cdma2000-UV simulator is a MATLAB implementation of the physical layer of the mobile commuciation technology cdma2000 1X. The simulator estimates the performance of transmissions between the user's mobile device and a cdma2000 1X base station under several test environments such as outdoor to indoor data transmissions and outdoor transmissions from users in a moving vehicle.
