How Dense is Ultra-Dense for Wireless Networks: From Far- to Near-Field Communications
TL;DR: The near-field propagation features in densely deployed network are discussed and the key challenges of applying interference management in ultra-dense wireless networks are shed and possible solutions are presented to suggest future directions.
Journal ArticleDOI
Superconvergence of discontinuous Galerkin methods for hyperbolic systems
TL;DR: In this paper, the discontinuous Galerkin method for the positive and symmetric, linear hyperbolic systems is constructed and analyzed by using bilinear finite elements on a rectangular domain, and an O(h^2)-order superconvergence error estimate is established under the conditions of almost uniform partition and the H^3-regularity for the exact solutions.
Proceedings ArticleDOI
An algorithm for discovering physical topology in single subnet IP networks
TL;DR: Simulation and analysis results show that this algorithm can discover the physical network topology accurately even if SNMP is not supported by some network elements.
Proceedings ArticleDOI
Double thresholds for judgment in cognitive spectrum sensing
TL;DR: A double thresholds scheme is proposed and it is proved this condition is satisfied universally in cognitive radio system and the maximal throughput increases while adopting this judgment scheme when parameters meet the condition.
Journal ArticleDOI
Interference Alignment With Finite Extensions in Partially Connected Networks
TL;DR: This paper investigates the feasibility of IA conditions with no channel extensions, and presents three theorems to characterize some necessary conditions, which implicitly impose the constraints on the upper bounds of achievable degrees of freedom with different channel extensions.
