IEEE 802 standardization on heterogeneous network interworking

As various radio access technologies and multi-mode terminals incorporating multiple network interfaces appear, research and development interest on heterogeneous network interworking increases. IEEE 802 groups have standardized technologies on interworking between heterogeneous IEEE 802 networks and between an IEEE 802 network and a cellular network. This paper analyzes technologies on heterogeneous network interworking of IEEE 802 standards and provides trends and requirements of future technology on heterogeneous network interworking.
