Abstract
This paper addresses a novel mechanism to solve the scalable problem in JRRM. Due to the flexibility and simplification, the fuzzy logic control (FLC) is chosen to make effective utilisation of resources. The combined fuzzy logic and multi-attribute decision making (MADM)-based algorithm can make proper initial RAT selection, horizontal handoff, vertical handoff, admission control and load balancing. The MADM-based RAT selection also has better efficiency than the traditional RRM mechanisms. By considering three kinds of traffic, voice, video and data respectively, the proposed scheme provides lower new call blocking probability and handoff call dropping probability in the heterogeneous wireless network that includes GSM/EDGE radio access network (GERAN), high-speed packet access (HSPA) and mobile worldwide interoperability for microwave access (WiMAX) RATs.
