1. Challenged Networking : An Experimental Study of new Protocols and Architectures
Abstract : With the growth of Internet, the underlying protocols are increasingly challenged by new technologies and applications. The original Internet protocols were, however, not designed for wireless communication, mobility, long disconnection times, and varying bandwidths. READ MORE

2. Opportunistic Networking : Mobility Modeling and Content Distribution
Abstract : We have witnessed two main trends in recent years that have shaped the current state of communication networks. First, the Internet was designed with the initial idea to provide remote access to resources in the network; today it is overwhelmingly being used for content distribution. READ MORE

3. Implementation and Experimental Evaluation of Wireless Ad hoc Routing Protocols
Abstract : A wireless ad hoc network consists of a number of mobile nodes that temporarily form a dynamic infrastructure-less network. New routing protocols that can adapt to the frequent topology changes induced by node mobility and varying link qualities are needed. READ MORE

4. Millimeter-wave Networking : Fundamental Limits, Scalable Algorithms, and Design Insights
Abstract : The current demands for extremely high data rate wireless services and the spectrum scarcity at the sub-6 GHz bands are forcefully motivating the use of the millimeter-wave (mmWave) frequencies. The main characteristics of mmWave communications are severe attenuation, sparse-scattering environment, huge bandwidth, vulnerability to obstacles and antenna misalignment, massive beamforming, and possible noise-limited operation.

5. Geographic Routing in Intermittently-connected Mobile Ad Hoc Networks : Algorithms and Performance Models
Abstract : Communication is a key enabler for cooperation. Thus to support efficient communication humanity has continuously strived to improve the communication infrastructure. This infrastructure has evolved from heralds and ridden couriers to a digital telecommunication infrastructures based on electrical wires, optical fibers and radio links. READ MORE
