Joint Price and QoS Market Share Game with Adversarial Service Providers and Migrating Customers

چکیده
In order to attract more and more customers, the price war between service providers (SPs) is becoming increasingly fierce. This kind of conflict situations has been analyzed and hugely studied by a plenty of works in the related literature. However unfortunately, almost all prior works neglect an important decision parameter, it is the promised quality of service which can be a serious advantage to register to an operator rather than the others. In this paper, we formulate the interaction between service providers as a non-cooperative game. First, each SP chooses the Quality of Service (QoS) to guarantee (it depends on the amount of requested bandwidth) and the corresponding price. Second, the customers decide to which SP to subscribe defining the market share for each SP. Then, each customers may migrate/churn to another SP or alternatively switch to “no subscription state” depending on the observed price/QoS. Furthermore, we build a Markovian model to derive the behaviour of customers depending on the strategic actions of the SPs. Finally, we provide extensive numerical examples to show the importance of taking price and QoS as a joint decision parameters and provide thereby some insights/heuristic on how to set them.

Playing Games with Genetic Algorithms: Application on Price-QoS Competition in Telecommunications Market
The customers use the best compromise criterion between price and quality of service (QoS) to select or change their Service Provider (SP). The SPs share the same market and are competing to attract more customers to gain more profit. Due to the divergence of SPs interests, we believe that this situation is a non-cooperative game of price and QoS. The game converges to an equilibrium position k...

The customers churn between service providers (SPs) due to better prices, better qualities of services or better reputation. Each provider is assumed to look for a maximized revenue, which depends on the strategy of the competitor. Several works present in the literature were based on the price as the only decision parameter, whereas others parameters such as quality of service (QoS) have a dec...

Network and processing overhead associated with web services is a significant challenge to its performance. As a result, web service providers often announce a service level agreement. This ensures that consumers, who pay for the service, can get the service at a given quality level. In this paper, we study the competition between two providers offering functionally the same web services, whe...
