Abstract:
An intelligent handover decision system is necessary for heterogeneous wireless mobile networks to fulfill user’s expectations in terms of the quality of services. With emerging realtime services, including multiple QoS parameters in handover decision process seems essential. In this paper, fuzzy logic is applied to enhance the intelligence of the handover decision engine. An adaptive traffic dependent fuzzy-based handover decision system (ATD-HDS), which employs multiple decision engines each optimized to a specific traffic type, is presented. The results show that, compared to a monolithic fuzzy-based handover decision system, the proposed ATD-HDS significantly improves the decision quality and algorithm execution time.
