These applications require a Quality of Service (QoS) which can be provided through proper network resource allocation. Due to the finite amount of resources, contention frequently occurs in networks. For this reason, a method to manage these limited resources in a fair and efficient manner is needed. Recently, pricing has been promoted as a method for allocating network resources. In this paper, we introduce a network resource pricing technique based on the competitive market model. Referred to as the ``spot market approach,'' the economic model consists of multiple dynamic competitive markets (spot markets) working asynchronously and independently. This allocation approach has all the advantages of other microeconomic-based methods; however, the spot market approach allows and encourages network dynamics to occur. In addition, the allocation method is practical to implement, has no limiting assumptions, and is able to achieve multiple types of fairness. Experimental results show that the spot market can quickly achieve fair allocations under realistic conditions.
