Research On Key Technology Of Wireless Heterogeneous Network Access

With the development of the wireless technology and network technology, people begin to realize that the heterogeneous network union which has multiple access methods, transmission rates and different kinds of quality of service requirements will be the trend of the future wireless network.The access technology among wireless heterogeneous networks becomes an important issue in wireless network research. In such a background, firstly the key technology of the wireless network is discussed. Then a proved hybrid routing protocol is adopt in heterogeneous network which is composed of different Ad Hoc networks. The protocol is designed to carry out an appropriate routing. The network selection is designed and implemented by considering both hops and delay time.In the end, the two-dimensional mesh model is used in the heterogeneous network. The traffic schedule proposals based on different parameters are given via analyzing the traffic and delay time in two networks.
