IMPLEMENTATION OF SEAMLESS SERVICE HANDOFF IN HYBRID WIRELESS-OPTICAL BROADBAND ACCESS NETWORK

摘要

In this paper, we propose a service handover supporting scheme under the help of wireless sensors in hybrid wireless-optical broadband access network (WOBAN). In this scenario, users can maintain access to their services uninterrupted even while moving or changing terminals. The hybrid network is composed of Ethernet-based passive network (EPON) and wireless network. The function of middleware developed is to transmit the service information between different user clients. While the wireless sensors are used for users' localization. We validate the service handover scheme in our test-bed and analyze the change of traffic. The implementation shows that our proposed scheme can support service handover successfully.
