Distributed Channel Access, Relay Selection and Time Assignment for QoE-Aware Relay Networks
IEEE Access, 2018 In this paper, we tackle the comprehensive problem jointing channel access, relay selection, and available time assignment for distributed relay networks which includes multiple source nodes and relay nodes.

Advanced Materials, EarlyView.2D α‐Co(OH)2 interleaved with Mo species displays an appealing dual functionality for the production and use of green hydrogen.Mo incorporation greatly benefits the electrochemical behaviour in Oxygen Evolution Reaction for H2 production, while the magnetocaloric response at liquid H2 temperature paves the way for alternative cryogenic refrigerants ...

Channel assignment with closeness multipath routing in cognitive networks
Alexandria Engineering Journal, 2013 Routing in cognitive networks is a challenging problem due to the primary users’ (PU) activities and mobility. Multipath routing is a general solution to improve reliability of connections.

Advanced Materials, EarlyView.We introduce a molecular strategy to assemble one‐dimensional (1D) materials into two‐dimensional (2D) van der Waals metal–organic frameworks (MOFs). Crystals of [FeX(pzX)(bpy)] (X = Cl, F) form anisotropic 2D layers that can be mechanically exfoliated into thin sheets.

Self-Organized Cognitive Sensor Networks: Distributed Channel Assignment for Pervasive Sensing
International Journal of Distributed Sensor Networks, 2014 We study the channel assignment strategy in multichannel wireless sensor networks (WSNs) where macrocells and sensor nodes are overlaid. The WSNs dynamically access the licensed spectrum owned by the macrocells to provide pervasive sensing services.

Computer and Information Science, 2010 The channel-assignment problem is important in mobile telephone communication. Since the usable range of the frequency spectrum is limited, the optimal channel-assignment problem has become increasingly important. The goal of this problem is to find a channel assignment to requested calls with the minimum number of channels subject to interference ...

Advanced Materials, EarlyView.The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

An approximation algorithm for a generalized assignment problem with small resource requirements. [PDF]
We investigate a generalized assignment problem where the resource requirements are either 1 or 2. This problem is motivated by a question that arises when data blocks are to be retrieved from parallel disks as efficiently as possible.
