— In this work, we examine a family of anti-collusion codes using the principle of “Orthogonal Spreading followed by the Inverse Fourier Transform (OSIFT)” as introduced in [...
Abstract— In a slot-synchronized wireless communication system, a set of signature sequences can be derived by circularly shifting a base sequence with good auto correlation prop...
— In this paper we discuss the design methodology based on the service-oriented architecture and agile development principles for wireless embedded and sensor networks (WSNs). Th...
Abstract—We tackle the problem of providing minimum datarate guarantees for different classes-of-service in an OFDMAbased network, while obtaining a high system throughput. Our a...
In this paper we introduce Social VPNs, a novel system architecture which leverages existing social networking infrastructures to enable ad-hoc VPNs which are self-configuring, s...
