Competitive Spectrum Pricing under Centralized Dynamic Spectrum Allocation
Dynamic Spectrum Allocation (DSA) has been viewed as a promising approach to improving spectrum efficiency. With DSA, Wireless Service Providers (WSPs) that operate in fixed spectrum bands allocated through static allocation can solve their short-term spectrum shortage problems resulting from the bursty nature of wireless traffic. Such DSA mechanisms should be coupled with dynamic pricing schem...
متن کاملInterference-aware high-throughput channel allocation mechanism for CR-VANETs
The incorporation of cognitive radio (CR) technology in vehicular ad hoc networks (VANETs) has given birth to a new network, namely CR-VANET, which facilitates the vehicular network to achieve communication efficiency in many resource-demanding applications including video and audio streaming, collision warning, gaming, etc. One of the primary challenges in this CR-VANET network is to allocate ...
متن کاملA Channel Allocation Mechanism for Cellular Networks
In cellular networks, call blocking causes lower customer satisfaction and economic loss. Therefore, the channel allocation for call block avoidance is an important issue. This study proposes a mechanism that considers the real-time traffic information (e.g., traffic flow and vehicle speed) and the user behavior (e.g., call inter-arrival time and call holding time) to analyze the adaptable numb...
متن کاملDistributed Opportunistic Channel Acquisition Mechanism in Dynamic Spectrum Access Networks
We present a distributed opportunistic channel acquisition mechanism in dynamic spectrum access (DSA) networks. A novel graph-multicoloring algorithm is proposed for secondary networks, in which, each network makes use only of the local topology information (i.e., information about itself and its one-hop neighbors) to resolve contentions during channel access. We show that the proposed algorith...
