A Survey on Next-Generation Hybrid Wireless Architectures

The Wireless communication networks are evolving rapidly. Current scenario demands connectivity anytime, anywhere with bandwidth intensive services such as videos, voice, text etc. These are high data rate services and have more QoS requirement. For such situation hybrid network emerged as a promising solution. Hybrid wireless network can be seen as group of individual networks integrated as a single network and mobile nodes present in the network, can connect either via gateway node or directly to other network. This paper discusses various hybrid wireless architectures. A classification of hybrid wireless network based on pricing schemes is also presented.
