Abstract [en]

Networked applications, no matter whether connected in a wired or wireless way, rely upon the ability of timely data delivery. The achievable throughput is a quality measure for the very task of a communication system, which is to transport data in time. This is of particular importance for nowadays trendy streaming applications such as digital TV, Internet Protocol (IP)-telephony, and gaming. Especially the higher throughput offered by 3G mobile systems (and beyond) as compared to earlier generations of mobile communications seems to pave the way for streaming applications into mobile environments. In this report a method is described that makes a decision between different communication technologies depending on different criteria and expectations stated by the end-user and perceived within the network itself. The Multi-Criteria Decision Making (MCDM) method together with the Analytic Hierarchy Process (AHP) method is used to achieve the concept of Always Best Connected (ABC). Two different groups of criteria are used: benefits and costs. Within the benefit group three metrics are used: Initial Delay (ID), Link Capacity (LC) and Direction Loss (DL) which are analyzed and used before a decision is made. These three metrics are weighted against each other. Finally a case study is presented, using the AHP together with the weighted metrics.
