摘要:
Utilization of wireless access points (APs) is optimized by dynamically managing transmitted AP power levels of beacon packets to control wireless AP coverage. This permits traffic congestion at one wireless AP to be reduced and shifted to other wireless APs. AP coverage management is provided by a centralized mechanism that employs various interpretations and/or measurements of client received power to handle dynamic changes in client workloads. The control does not require protocol changes to clients that utilize a wireless AP and can also incorporate hand-off costs and/or manufacturer specified power level constraints. Thus, these techniques can be employed in existing wireless LANs without impacting clients. Various instances are employable with continuous power and/or discrete power based wireless APs, providing a non-client impacted means to increase throughput and/or load balance.

A system that facilitates efficient code construction comprises a component that receives a first code and a transformation component that transforms the first code to a new code. The new code has essentially same length parameters as the first code but is hidden to a computationally bounded adversary. The first code can be designed in the noise model and appear random to a computationally bounded adversary upon transformation.

The described implementations relate to enhanced media subscription services. One technique provides digital rights restricted media to a consumer for a period. At the end of the period, based at least in part on consumer use, the technique removes the digital rights restrictions from some of the media and deletes other of the media.

The described implementations relate to rent-to-own media. One technique provides digital rights restricted media to a consumer on a rent-to-own basis. The technique also removes the digital rights restrictions from the media upon completion of the rent-to-own basis.

Described herein is a method for executing a positional auction. The method includes acts of receiving a keyword and executing at least one multi-item single unit demand auction and at least one single-item auction, wherein a plurality of bidders submit bids in the at least one multi-item single unit demand auction and the at least one single-item auction. The method further includes an act of ranking the plurality of bidders based at least in part upon bids submitted in the at least one multi-item single-unit demand auction and the at least one single-item auction. The method additionally includes an act of allocating a subset of the plurality of bidders to particular positions on a search results page based at least in part upon the ranking.

The claimed subject matter provides a system and/or a method that facilitates reducing spam in search results. An interface can obtain web graph information that represents a web of pages. A spam detection component can determines one or more features based at least in part on the web graph information. The one or more features can provide indications that a particular page of the web graph is spam. In addition, a robust rank component is provided that limits amount of contribution a single page can provide to the target page.

An overlay network and scheme for building and using the overlay network are described. As the overlay network is built, new nodes joining the network are connected randomly with other nodes which results in a random graph as the network topology. The network is fully scalable, with each new node providing the same number of network connections for output to other nodes as it consumes when it joins the network. In addition, network coding is implemented at each node to mix packets of data entering each node using random linear functions. The network coding at each node generates new packets that are independent combinations of original data packets entering the node. The new coded packets make the distribution of data to other nodes more efficient and robust.

Systems and/or methods are presented that can employ an ad object comprising a data packet(s) to facilitate providing an advertising platform that is ecosystem independent and can support various advertising models, such as affiliate, viral, and/or word-of-mouth (WOM) advertising. The data packet can be associated with an advertisement for a product(s) and/or service(s) and can include a mechanism(s) that facilitates enabling users to reproduce the data packet and associated advertisement in different sites, such as user sites. As the data packet propagates through a community network, the data packet can receive and accumulate data, such as data relating to purchases, comments, or ratings, storing such data in the data packet and displaying a portion of such data with the advertisement to facilitate WOM advertising. The data packet facilitates providing incentives to users who perform desired actions (e.g., purchases, syndication) related to the advertisement.

Mechanisms for tracking power unit usage allow power units to be exchanged rather than recharged. Users can purchase power unit subscriptions that are tracked on a per entity basis to allow exchange of power units during the subscription period. The subscriptions can also account for life cycle costs of the power units. Subscriptions can be based on a time period, on an amount of power, and/or on a number of power unit exchanges. In one instance, power unit vending stations interact with a centralized server to allow power unit exchanges at any number of disparate locations.

The claimed subject matter relates to an architecture that can facilitate the commoditization of both products and product markets in resale domains in order to aid in quantifying a value of used product as well as to enhance efficiencies and/or profits in resale markets. In one aspect, the architecture can determine a recommended (e.g., average) price and listing fee for a product. In another aspect, desired (e.g. indicated by the seller) values can be provided and based upon various market factors and differences between the desired values and the recommended values, the architecture can determine a variety of probabilities relating to the conversion of the product, as well as provide suggestions for increases the potential for a conversion. In addition, the architecture can identify and capitalize on arbitrage opportunities within the market.
