With the integration of heterogeneous network protocols, roaming among different networks becomes feasible. The subjects with most attention are the guaranteed quality of services (QoS) and the handoffs without disconnections. This paper proposes a roaming node encoding algorithm in wireless communications, in order to define nested network nodes, without duplicate encodings, and to rapidly confirm...
The wireless network environment in the future is going to include various heterogeneous wireless networks. In a heterogeneous wireless network environment, vertical handoff processes caused by the movement of users are inevitable. However, the research related to how to achieve seamless vertical handoff and improve QoS guarantees in today's heterogeneous wireless networks is still something to work...
With the popularization of the wireless and wired networks, this paper will regard WiFi, WiMAX and CATV (DOCSIS) as the research objects, focus on the relevant technology of seamless layer 2 framework for heterogeneous networks. Seamless communication is the most important topic of this paper, beside it, routing cost and QoS guarantees, will also be important problems that must be considered in the...
The development of wireless networks brings people great convenience. More state-of-the-art communication protocols of wireless networks are getting mature. People attach more importance to the connections between heterogeneous wireless networks as well as the transparency of transmission quality guarantees. In this paper, WiFi wireless networks and WiMAX mobile communication system are selected as...
