Network Selection Strategy in Heterogeneous Wireless Networks
Next generation communications will offer a wide range of services available to users anywhere at any time. How wireless users access those services depends on the current user context: location, characteristics of the available networks, user preferences, application requirements and terminal capabilities. The vision is that users will not be tied down to a long-term contract with one single o...
متن کاملReputation-based Network Selection Solution in Heterogeneous Wireless Network Environments
The significant developments in terms of both mobile computing device (e.g., smartphones, tablets, laptops, etc.) and the wireless communication technologies (e.g., LTE, LTE-Advanced, WiMAX, etc.), lead towards a converged heterogeneous wireless environment. In this context, the user will be facing the problem of selecting from a number of Radio Access Networks that differ in technology, covera...
متن کاملHybrid Approach for Radio Network Selection in Heterogeneous Wireless Networks
Next generation wireless network (NGWN) will be composed of multiple radio access technologies (RATs) and domains. Radio network selection (RNS) is the mechanism which decides how to select the most suitable RAT based on the discovered accesses, QoS constraints, operator policies, user preferences and available system capacity and utilization. Optimizing the selection process is an important is...
متن کاملDynamic Network Selection in Wireless LAN/MAN Heterogeneous Networks
In future generations of wireless networks, it is expected that different users with various multi-homed personal wireless devices will have the option of accessing their desired services via different available radio access networks. Given the variability of the radio environment properties and user mobility, the availability and characteristics of an access network will change in time and are...
متن کاملNew Optimized Network Selection Decision in Heterogeneous Wireless Networks
The expected growth in radio access technologies (RAT's) such as wireless technologies (802. 11a, 802. 11b, 802. 15, 802. 16, etc. ) and cellular networks (GPRS, UMTS, HSDPA, LTE, etc. ) requires efficient vertical handoff algorithm. Variety of vertical handoff algorithms (VHA) have been proposed to help the user to select dynamically the best access network (BAN) in terms of quality of se...
