Load Sharing in Heterogeneous Wireless Systems Using Dynamic Load Measures

We suggest load sharing algorithm that can be applied between heterogeneous wireless systems. The basic idea of sharing load between different systems is to transfer users in a highly loaded system to a lowly loaded system. In this scenario, we need a common load measure that can be used in different systems. The degree of a load in cellular systems is affected by many factors such as the number of users, channel conditions and the required QoS(quality of service). To accommodate such factors in a load measure, we propose a new measure based on each user´s satisfaction level. The validity of the measure and the performance of the load sharing algorithm are tested by simulation
