Resource management scheme based on position and direction for handoff control in micro/pico-cellular networks

Abstract

We propose a handoff control scheme to accommodate mobile multimedia traffic based on the resource reservation procedure using the direction estimation. This proposed scheme uses a novel mobile tracking method based on Fuzzy Multi-Criteria Decision Making (FMCDM), in which uncertain parameters such as Pilot Signal Strength (PSS), the distances between the Mobile Terminal (MT) and the Base Station (BS), the moving direction, and the previous location are used in the decision process using the aggregation function in fuzzy set theory. In performance analysis, our proposed scheme provides a better performance than the previous schemes.
