The establishment of common control channel (CCC) is an immense challenge in cognitive radio networks (CRNs). Since the channel number is large and the channel access is opportunistic, the process (a.k.a. rendezvous) that any pair-wise nodes (i.e. rendezvous pair) find a common channel to establish a control channel for communication is hard to achieve, especially in a distributed CRN. Researchers...
In the Digital Rights Management (DRM) platform, the weak security of user authentication online and the digital content usage offline are analyzed, and a dual-factor dynamic authentication scheme is designed, which is based on the Personal Identity Number (PIN) authentication and the hardware USB Key digital certificate authentication. On this basis, the architecture of the dynamic certification...
BACnet (building automation and control networks) is a standard data communication protocol for building automation and control systems. BACnet adopts master-slave/token-passing (MS/TP) as one of its local area networking options. The MS/TP protocol is designed specifically for building automation and control systems. In this paper, the authors firstly analyze the feasibility of MS/TP protocol used...
Traditional contract net protocols can simply and flexibly solve the negotiation problem of multi-agent system (MAS). But they canpsilat work very well within the large scale system environment and is ineffective to solve the multi-issue negotiation problem. This paper investigates the reputation contract net protocol (RCNP) and proposes a novel contract net negotiation model based on RCNP. The model...
BACnet (Building Automation and Control networks) is a standard data communication protocol for building automation and control systems. The purpose of the BACnet network layer is to provide the means by which messages can be transmitted from one BACnet network to another regardless of the BACnet data link technology in use on that network. BACnet routers are devices that interconnect two or more...
BACnet (building automation and control networks) is a standard data communication protocol for building automation and control systems. BACnet adopts Master-Slave/Token-Passing (MS/TP) as one of its local area networking options. The MS/TP protocol is designed specifically for building automation and control systems. In this study, we introduce a new algorithm of implementing bandwidth dynamic allocation...
