Description: 异构网络的融合问题 通信技术近些年来得到了迅猛发展，层出不穷的无线通信系统为用户提供了异构的网络环境，包括无线个域网(如Bluetooth)、无线局域网(如Wi-Fi)、无线城域网(如WiMAX)、公众移动通信网(如2G、3G)、卫星网络，以及Ad Hoc网络、无线传感器网络等。尽管这些无线网络为用户提供了多种多样的通信方式、接入手段和无处不在的接入服务，但是，要实现真正意义的自组织、自适应，并且实现具有端到端服务质量(QoS)保证的服务，还需要充分利用不同网络间的互补特性，实现异构无线网络技术的有机融合。

From midnight, frequency division, code assigned to the current air separation, from TDMA, CDMA to OFDMA, from a single antenna to the smart antennas, advanced technology with each passing day, one after another. With the emergence of these new technologies, WiMAX network is becoming the next generation of communication systems competitors. Many people think that WiMAX if not eventually replace 3G, will also be building a foundation for future 4G networks, so many international communications equipment manufacturers who are high hopes for the emergence of WiMAX, Nortel Networks or even to abandon the traditional 3G research and development and specializing in WiMAX.

Description: There is a growing interest of wireless
operators to migrate their existing 3G networks to
different 4G technologies such as Wi MAX and L TE. In
this heterogeneous environment of wireless networks
and architectures, one of the major concerns is how to
allocate network resources efficiently to diverse traffic
classes with different QoS constraints. Further it has
been convincingly demonstrated through numerous
high quality studies that multimedia traffic found in
modern wireless networks exhibits Long-Range
Dependence (LRD) and self-similarity, a phenomenon
which cant' be captured by traditional traffic modeling
based on simplistic Poisson model.
