HYSTERESIS PLUS TIMER BASED HANDOVER INITIATION ALGORITHM FOR MICROCELLULAR SYSTEMS

摘要

This paper presents a new handover initiation algorithm based on relative signal strength measurements without averaging, and a timer. The performance metrics used are average number of handovers per cell boundary crossing, and handover initiation delay. Both of these needs to be minimized. Proposed algorithm is compared with the conventional algorithms based on averaged signal strength measurements. Results show that the new algorithm yields the same performance as that obtained through the latter. Averaging of measurements always makes the handover process sluggish. The proposed algorithm does not employ averaging of received signal Strength measurements making it a fast handover initiation algorithm, particularly suitable for implementation in microcellular systems.
