Welcome to the Computer Networking Research Laboratory


Enabling communication for high-speed distributed collaborative applications such networks of weather radars require ultra fast, efficient protocols and protocol implementations. In contrast, Wireless Sensor Networks (WSNs) demands for low bandwidth, power efficient, fault tolerant, autonomous protocols and protocol implementations with lower complexity.

CNRL is a research laboratory at the Department of Electrical and Computer Engineering, Colorado State University, USA. We are involved in research activities ranging from protocol design and implementation from weather radars to tiny micro sensors. Present and past projects at CNRL include:
