Nowadays, the access selection methods are done based on operator incentives using static and predefined rules that are not sufficient once the number of deployed access technologies and mobile services is increasing and the access technologies are becoming more diverse in terms of connectivity characteristics, then today’s access selection practices are not adequate anymore. We need to think about end-user preferences in a decision making process. Two new distributed decision making algorithms called the Network Centric and the Terminal Centric algorithms exploiting Ambient Networks mechanisms are presented. These algorithms use a richer set of constrains and rules. In order to evaluate these algorithms from an end-user perspective, we introduce a new performance index called the User Satisfaction Index. We present our simulation model, performance results and analysis. The results indicate that the cooperation between networks increases the network utilization and service availability. The benefits from an end-user perspective are expressed using the proposed performance metric called User Satisfaction Index. Finally, we discuss on further challenges of a decision making for information centric networking.
