In electronic auction applications, small-value merchandise is often distributed. We call this kind of auction micro auction. Compared to traditional general-purpose electronic auction, micro electronic auction has its own special requirements. Especially, micro auction must be very efficient: the cost of the auction protocol must not be over the cost of the merchandise for sale. Although the m...

Due to the dramatic increase of spectrum demand, efficient usage limited resources has become a crucial issue for next-generation wireless networks. Auction-based trading, utilization and pricing have many promising features proven be fair consistent way secondary trading management. In this paper, we present mathematical approach future market where multiple buyers (secondary network operator)...

We study the impact of crossholdings on the efficiency of the standard auction formats. If both bidders with crossholdings and bidders without crossholdings participate in the auction process, neither the first-price auction nor the second-price auction is efficient. The ascending auction is not equivalent to the second-price auction. In a class of examples, the ascending auction is efficient. ...

Some of the new trends emerging in future wireless networks enable a vastly increased fluidity in accessing a wide range of resources, thus supporting flexible network composition and dynamic allocation of resources to virtual network operators (VNOs). In this work we study a new resource allocation opportunity that is enabled by the cloud radio access network architecture. In particular, we in...

Auction is one of the pricing mechanisms that has been widely applied in various fields. The auction market which was to non-agricultural goods now developed agriculture such as chili Panjatan District, Kulon Progo Regency. purpose this study describe institutional profile and process implementing managed by farmers Descriptive analysis used analyze process. results showed District an instituti...

Cognitive Radio is gaining popularity and acceptance all over the world as an efficient way to utilise the limited wireless spectrum resources. Out of the many design requirements of Cognitive Radio such as spectrum sensing, spectrum allocation, power control etc., spectrum sharing is one of main challenges to ensure peaceful co-existence of the primary and secondary users. Since multiple users...

The last ten years has seen an explosion in uses of wireless technologies. This, in turn, has driven a demand for "more" spectrum to support these uses. A recent spectrum license auction by the Federal Communications Commission ("Commission" or "FCC"), which regulates all civilian uses of wireless technologies in the United States, generated almost $14 billion.' The FCC's most recent report on ...

When combinatorial bidding is permitted in auctions, such as the proposed FCC auction #31, the resulting full valuations and winner-determination problem can be computationally challenging. We present a branch-and-price algorithm based on a set-packing formulation originally proposed by Dietrich and Forrest (2002). This formulation has a variable for every possible combination of winning bids f...
