1. A method of sharing environmental context information between wireless devices, comprising: receiving, by a receiving device, a discovery query and one or more responses to the discovery query; decoding the discovery query and at least one of the one or more responses to the discovery query to determine one or more requested environmental context parameters and one or more satisfied environmental context parameters that can be provided by at least one responding device transmitting the received one or more responses; based on the one or more requested environmental context parameters and the one or more satisfied environmental context parameters, determining a set of outstanding environmental context parameters; based on the outstanding environmental context parameters and a set of environmental context capabilities of the receiving device, determining a set of available environmental context parameters of the one or more requested environmental context parameters that can be provided by the receiving device; generating a response to the discovery query indicating the set of available environmental context parameters that can be provided by the receiving device and indicating that the receiving device can provide one or more of the set of available environmental context parameters in exchange for one or more costs, the one or more costs representing one or more of a quantity of advertising, an amount of monetary currency, and an electronic service; and, transmitting, by the receiving device, the response to the discovery query.
