Handoff management scheme for multimedia mss-networks using genetic algorithms

A new method of handoff management scheme using the genetic algorithm for use in MSS networks is proposed in this paper. An analytical model of the inter beam handover is derived from the constellation diversity characteristics, the spotbeam dimensions and the user´s location. Synchronous and asynchronous best effort traffic model are considered. The real mobility management task (inter beam bandover) is proposed. An analytical model of the inter beam handover is derived from the constellation diversity characteristics, the spotbeam dimensions and the user´s location. The GA concept is applied to allocate the new can at one channel in one cell to another one where the traffic intensity is zero or low at that time. Simulation results show that the QoS performance in terms of the call blocking, call dropping probability and the capacity.of the system (Erlang per channel) can be improved.
