A Survey of the Key Technologies of Heterogeneous Wireless Converged Network

Abstract

Heterogeneous Wireless Converged Networks (HWCN) are expected to be the trends of next generation wireless network. It will pose great impacts on way of communication. HWCN is a brand new research area and many problems still need to be solved. Firstly, the background and development of HWCN are summarized, and its challenges and analyzed. Then from the perspective of network architecture, access selection algorithms, resource management algorithms and vertical handover strategies are discussed. Finally, the next step research suggestions of load balancing, green communications and intelligent characteristics are also proposed.
