Vertical handover decision-making algorithm using fuzzy logic for the integrated radio-and-OW system

Journal article

Due to the complementary nature of radio and optical wireless (OW) both in capacity and coverage, the combined use of both for data transmission could have advantages over a single media. However, big technical challenges for vertical-handover (VHO) strategy arise for such an integrated system. According to different interruption types and traffic modes, two basic VHO schemes can be applied: immediate VHO (I-VHO) and dwell VHO (D-VHO). This paper proposes a novel fuzzy-logic (FL)-based decisi...
