We consider a two-player game involving a large incumbent (or incumbent oligopoly) and small entrant into a cellular-wireless access provider marketplace. The entrant's customers must pay roaming charges. We assume that the roaming charges are transparent to the user and regulated to prevent an incumbent from creating barriers to entry in the marketplace. To be able to reckon suitable (regulated)...
We consider a scenario in which a regulator owns the spectrum in a region. Two service providers lease spectrum from the regulator and set up a base station each to serve mobile subscribers. This leads to a hierarchical game with players at two levels- the mobile subscribers at level 1 and the service providers at level 2. In the game at level 1, each mobile subscriber chooses a service provider to...
Efficacy of proliferation of commercial wireless networks can be substantially enhanced through large scale cooperation among different providers. If a group of providers cooperate by allowing customers to be served by the resources of the whole group rather than just those of their own providers, they have the potential to utilize their resources more efficiently and enhance the quality of service...
We consider a network in which several service providers offer wireless access service to their respective subscribed customers through potentially multi-hop routes. If providers cooperate, i.e., pool their resources, such as spectrum and base stations, and agree to serve each others' customers, their aggregate payoffs, and individual shares, can potentially substantially increase through efficient...
We consider a framework in which several service providers offer downlink wireless data access service in a certain area. Each provider serves its end-users through opportunistic secondary spectrum access of licensed spectrum, and needs to pay primary license holders of the spectrum usage based and membership based charges for such secondary spectrum access. In these circumstances, if providers pool...
A decision maker (Actor) has to decide which of several available resources to use in the presence of an adversary (Controller) that can prevent the Actor of receiving information on the state of some of the resources. The Controller has a limitation on the amount of information it can conceal. We formulate this problem as a game and compute the most harmful behavior of the Controller and the best...
We consider a setting in which several operators offer downlink wireless data access services in a certain geographical region. Each operator deploys several base stations or access points, and registers some subscribers. In such a situation, if operators pool their infrastructure, and permit the possibility of subscribers being served by any of the cooperating operators, then there can be overall...
