Comparison of alternative handoff strategies for micro-cellular mobile communication systems
G.N. Senarath, David Everitt · 2002
The drop-out probability and the unnecessary handover performance of several handover schemes have been investigated using a simulation model which incorporates detailed representation of mobility, traffic and propagation environments. Specifically the overall performance of variable hysteresis level handover schemes are investigated. The performance under various mobility conditions are presented for both Manhattan city environment and hexagonal cell layout. Also the performance dependency on more critical input parameters such as mobile speed and correlation of sample measurements, is presented. It is shown that an environment dependent, variable hysteresis function can be devised by closely studying the system handover behaviour to give the optimum overall performance.>
