“…Sharma et al [7] proposed a vertical handoff system between WLAN and GPRS links by using an extension of the Mobile IP protocol. While [8] intends to achieve ABC over WLAN and WiMAX by using a new mechanism to detect QoS support of the underlie networks. The authors in [9] proposed an algorithm named Fully Decentralized Nash Learning Algorithm to select an access network for Group Vertical HandOver (GVHO) in Heterogeneous Networks.…”

Mobile communication has become the preferred choice of personal communication today. With the rapid proliferation of wireless network technologies, heterogeneous wireless network environments increase more and more. Such environments provide multiple access networks simultaneously for mobile users. Each mobile user wishes to get connected to Internet using the access technology that best suits his needs at any point in time. Always Best Connected is considered as a special concept for mobile users to select their suitable access networks. In this paper, we have presented two scenarios which are based on Always Best Connected concept to provide, for a smart vehicle moving in a road network installed with multiple access technologies, an always best connected service at any point in time. In the first scenario, we assume that the mobile user (vehicle) has complete information on the road network (all access technologies installed in the road network). Whilst the second scenario is the same as the first one except that the mobile user periodically receives a partial information on the road network (only the access technologies installed in the edges which are immediately accessible by mobile user). For both scenarios, we have proposed a graph model to characterize the observed mobility pattern. Also, two algorithms are proposed to find the optimal path that provides always best connected service for vehicles in both scenarios.

“…Given a set of flows, researchers [6] model ABC as a knapsack problem while [7] formulates ABC as a variant of bin packing problem and presents a series of approximation algorithms based on First Fit Decreasing (FFD) algorithms. While [8] intends to achieve ABC over WLAN and WiMAX by using a new mechanism to detect QoS support of the underlie networks, other researches [9] consider both user preference and attributes of access networks and formulate ABC as a problem of MCDM.…”

Selecting transparently a proper network connection for voice communication will be a fundamental requirement in future multi-mode heterogeneous wireless network. This paper extends Always Best Connected (ABC) to a fine-grain paradigm called Always Best Network Connection (ABNC) to address this issue. Instead of selecting a best access network as in conventional ABC, ABNC enable users to select a best network connection, which consists of source and destination access network pair, to satisfy quality constraint and users' preference. To support ABNC, we develop a user profile to specify network connection priority. Meanwhile we extend SIP and propose a network selection information service (NSIS) based on MIH (Media Independent Handover) to collect information of both source and destination access networks for decision making. Finally, AnalyticHierarchy Process (AHP) is used to recommend a network connection with assistance of user profile and NSIS. An example is illustrated to show that AHP can successfully select a good network connection that fulfill the requirement of users.

“…But the paper has not provided any technical details to obtain those parameters. In [4], the authors have proposed a mechanism that supports ABC QoS for IEEE 802.11e WLAN and IEEE 802.16d WiMAX networks. The handoff decision is made by comparing the QoS parameters provided by AP and BS.…”

A QoS-Based Vertical Handoff Scheme for Interworking of WLAN and WiMAX

In this paper, we investigate the issue of vertical handoffs in heterogeneous wireless networks. A QoS-based vertical handoff scheme for WLAN and WiMAX interworking networks is proposed with aim to provide always best service to users. We also present a simple, yet efficient method to estimate the available bandwidth in WLAN and WiMAX networks to evaluate the real-time status of the overlay networks and make a handoff decision based on the information. By our proposal, a handoff process will not only be triggered by unaccepted signal strength but also by unsatisfied QoS parameters. Simulation results show that the proposed scheme can keep stations always be best connected with their QoS requirements met. TThis full text paper was peer reviewed at the direction of IEEE Communications Society subject matter experts for publication in the IEEE "GLOBECOM" 2009 proceedings.
