Abstract
An intelligent hand over decision system (HDS) is
essential to heterogeneous wireless mobile networks in order to
fulfill user's expectations in terms of universal and seamless
services. With emerging real-time services in heterogeneous
networking environment, including multiple QoS parameters in
hand over decision process seems essential. In this paper, fuzzy
logic is applied to enhance the intelligence of HDS. A new fuzzybased
HDS design with the aim to reduce design complexity of
fuzzy engine without sacrificing handover decision performance
is proposed in the paper. The results show that, compared
to non-fuzzy-based (i.e., SAW and AHP) and existing fuzzybased
decision techniques, the network selection performance
of proposed HDS design is significantly better than SAW and
AHP, and is superior to an existing fuzzy-based technique. The
proposed HDS design is then enhanced by incorporating an
adaptive mechanism enabling a further improvement in terms
of the network selection performance.
