Abstract
The pre-emption procedure is an important part of the Radio Resource Management (RRM) when dealing with the emergency traffic. It allows resources to be allocated to higher priority connections by pre-empting lower priority connections. The provision of the pre-emption mechanism becomes much more important in the case of satellite systems
such as the Inmarsat Broadband Global Area Network (BGAN) system which aids in providing the communication during a catastrophe. This paper focuses on the preemption framework for a UMTS based satellite systems. Three algorithms have been proposed, Greedy, SubSetSum and Fuzzy pre-emption algorithm. Extensive simulations are carried out for the three algorithms and their performances are compared against each other. Simulation results show that the Fuzzy pre-emption algorithm performs better than the other two algorithms.
