To sup- port 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), Net- work 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 respon- sible 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 scena- rios. Results of the experiment indicate the advantages of the proposed scheme. Keywords Handoff, mobility management, neuro-fuzzy, wireless network 1. Introduction It is avouched that next generation of wireless net- works will utilize different access technologies such as WLAN(802.11x), WWANs such as General Packet Radio Service (GPRS), Universal Mobile Telecommu- nications System (UMTS), Code division multiple access (CDMA) and WiMAX (World Wide Interop- erability for Microwave Access) and other emerging access technologies such as mesh networks. The main aim of cooperation of diverse wireless technologies is providing ubiquitous access to demanded services. Each one of above mentioned technology has own specification in term of QoS level, coverage area, bandwidth and cost. The incoming mobile terminals (MTs) such as smart phones and PDAs, will capable of multimode access interface to supporting different types of radio access technologies on single equipment. Beside, with rapid growing of wireless infrastructure technology, the areas with multiple coverage of the umbrella-like wireless access are increased. Hence supports of nomadic users to enjoy seamless connec- tion, have been focused by many researchers in acade- mia and industrial. In heterogeneous data networks, an accurate decision on handoff has a significant impact on the throughput of the system. More precisely, one of the main issues of the handoff management is con- cerned with deciding the best attach point while a MT is in the coverage area of multiple diverse networks that been shown in Figure 1. In zone A and B, mobile host locate in three and two candidate access network, respectively. Besides, the traditional handoff mechan- ism, actually was based on received signal strength (RSS) or received power (P) which are not usable for heterogeneous wireless environments due to diversity of physical links. The above mentioned issues are the main motivation behind of this works. Also propose efficient handoff decision scheme with consideration of user preference, QoS of current service and available networks conditions can assumed as objective of this studies. The following issues are important design goals for our cross-layer mobility solution: 1- Small handoff latency and efficient data packet delivery. 2- Ease of administration and deployment. 3- Scalability and robustness. 4- Application transparency. 5- User preferences and service cost. 34
