    Near-Optimal Truthful Auction Mechanisms in Secondary Spectrum Markets

    In this paper, the authors study spectrum auction problem where each request from secondary users has spatial, temporal, and spectral features. With the requests of secondary users and the reserve price of the primary user, their goal is to design truthful mechanisms that will either maximize the social efficiency or...

    An Open MPI-Based Cloud Computing Service Architecture

    Cloud computing is generally accepted as the workable solution for computation intensive problems such as big data analysis. Among the major building blocks for the underlying infrastructure, MPI (Message Passing Interface) is one of the most effective solutions. This study aims to propose a Java-based service architecture using Open MPI...

    Aggregation of DTN Bundles for Channel Asymmetric Space Communications

    Delay/disruption Tolerant Networking (DTN) is considered one of the most suitable technologies to handle challenging space communications. Aggregation of multiple DTN bundles within a data transport block for space communications has been in controversy for years. In this paper, the authors present an experimental investigation, using a PC-based testbed, of...

    Analog Turbo Codes: Turning Chaos to Reliability

    Analog error correction codes, by relaxing the source space and the codeword space from discrete fields to continuous fields, present a generalization of digital codes. While linear codes are sufficient for digital codes, they are not for analog codes, and hence nonlinear mappings must be employed to fully harness the...
