A Host Mobility Support with Adaptive Network Selection Method in Hy-brid Wireless Environment

Abstract

The B3G or 4G of cellular/wireless communications network is expected to be purely IP-based and consist of heterogeneous access networks from 3G cellular, WiFi, WiMAX and a converged core network. To support the mobile host in the hybrid overlay wireless, a cross-layer vertical handoff control method has been proposed. Implemented architecture is composed of four part; Connection Profile Manager (CPM), Network Access Assistance (NAA), Neuro-Fuzzy Decision Engine (NFDE), and Peer-bind Connection Manager (PCM). The most effective connection is selected based on the attributes from the multi-layer platform that provided handoff decision component which is responsible for handoff decision. The proposed network selection algorithm is based on hybrid neuro-fuzzy concept with low packet loss and latency. We have analyzed our implemented model on different scenarios. Results of the experiment indicate the advantages of the proposed scheme.

VHITS: Vertical Handoff Initiation and Target Selection in a Heterogeneous Wireless Network

“…A host mobility support with adaptive network selection method based on neurofuzzy decisions is proposed in [99]. The scheme is based on adaptive fuzzy logic system where the rules are derived and extracted from given training data.…”

“…The vertical handoff process should be triggered when any of the following conditions become true [99,114]:…”
