Dynamic Spectrum Leasing (DSL) in Dynamic Channels
Dynamic Spectrum Leasing (DSL) was recently proposed in [1]–[4] as a new way to achieve dynamic spectrum sharing (DSS). Unlike previously considered dynamic spectrum access (DSA) proposals, DSL allows for the spectrum owner, called the primary user, to dynamically adjust the amount of interference it is willing to tolerate from secondary users. In response, the secondary users update their tran...
متن کاملDynamic Spectrum Leasing with Two Sellers
This paper studies dynamic spectrum leasing in a cognitive radio network. There are two spectrum sellers, who are two primary networks, each with an amount of licensed spectrum bandwidth. When a seller has some unused spectrum, it would like to lease the unused spectrum to secondary users. A coordinator helps to perform the spectrum leasing stage-by-stage. As the two sellers may have different ...
متن کاملExtending ODRL to Enable Bi-Directional Communication
Current rights expression languages (RELs) only allow for rights holders to dictate terms to the end users. This limits their use as a means for negotiating electronic contracts and end users are not able to request changes in their rights contracts. In this paper we propose extensions to ODRL that allow end users to request changes and for the rights holder to grant or deny these changes. Thes...
متن کاملReliable Multicast via Satellite: Uni-directional versus Bi-directional Communication
We investigate reliable multicast communication over satellite networks. We compare a scenario where receivers can use a feedback channel to signal loss to a scenario where no feedback channel is available. We show that the introduction of a feedback channel is the key to allow for bandwidth-e cient, robust, and fully reliable multicast communication via satellite.
متن کاملBi-Directional Visible Light Communication for Internet-of-Things devices
Traditional methods of wireless communications are saturating in terms of data rate, frequency spectrum and reliability. Visible light communications has attracted interests in many fields due to widespread commercial availability of LED lights and partly due to limited bandwidth available on the radio communication. It is even more effective for Internet-of-Things(IoT) devices which require ve...
