The Wireless and Networking research group engages in fundamental research on mobile computing and networking. We strive to advance the state-of-the-art and to create new computing experiences with mobile, pervasive, personal, and embedded devices. Our group members' research interests span wireless networking, mobile systems, phone-based computing, embedded systems, security, and new networking paradigms. We emphasize both analytical and empirical approaches, and build actual systems to validate theoretical results and refine system principles from experimental work.

• We did it again -- we won the Best Demo Award at MobiSys 2008!
• Latest paper acceptance: Sigcomm'08.
• Congrats to our 2007-2008 interns - 3 to Stanford with fellowships, 1 to CMU, 1 to U Mich, 1 to GATech (they also had admissions to MIT, Princeton, U Washington, USC, Rice, U Wisc, U Maryland, etc.)
• Our BeepBeep system won a Best Demo Award at SenSys 2007!
• Major publications in 2007: MobiSys'07, SenSys'07.
• Our MobiUS demo won the Best Demo Award at MobiSys 2007!
• Local news coverage for our group's MobiUS project (mostly in Chinese)

• Mobile Systems and Sensor Network Research:

  We focus on designing and implementing new mobile platforms that enable "better-together" mobile application paradigms and smoother mobile user experiences. We develop key enabling technologies such as high-accuracy localization, easy yet secure network setup and device pairing, systematic and adaptive workload offloading, device collaboration etc.

  We propose and promote new concepts, applications and services that exploits contextual awareness and social aspects of mobile devices. We also research on novel ways to improve the robustness and security of modern mobile phones.

  Our sensor network research mainly concentrates on the home scenarios which are undergoing rapid innovation and will be the key market focus for the coming years. Green, convenience and security are our major research targets.

• Wireless Networking:

  We focus on fundamental wireless technologies that will enable various new applications and mobile services to profoundly change lives. We envision that the rapid increase in computing will have fundamentally impact on the change of the wireless communication paradigm. Software-based cognitive wireless systems will become much more powerful, flexible, and efficient compared with existing wireless technologies.

  We are building a software-based, open, flexible and highly efficient research platform to enable a range of wireless research in physical layer, medium access control, and cross-layer optimization. We are developing novel programming models and various tools to greatly reduce the effort involved in implementing wireless systems. Consequently, our wireless research platform provides a venue for innovative wireless system research that we feel will encourage the research community to develop and test novel technologies for real-world deployment.

  We are promoting a coherent design for wireless communication and networking. We explore the new problem space and take a clean-slate design approach for revolutionary wireless networks and systems based on software radio technologies. We are currently working on new energy-efficient discovery protocol, routing, transmission adaption, new network coordination mechanisms and system support.

• Internet and data center networking:

  We are working on projects that improve user experiences of the Internet online services from a networking perspective. Online services need support from both the Internet that provides pipes for user access and data center networks that connect backend servers. On the Internet aspects, we are using data centric approaches to solve hard Internet networking problems. For example we utilize the huge amount of geolociaton information contained in the Web and Internet to determine the geolocations of IP addresses and the network distance of two Internet hosts. In data center networking (DCN), we are working on scaling and fault tolerance of DCN, DCN infrastructure consolidating, DCN resource management and congestion control, and application and OS support in DCN.
