蜂窝网络和AdHoc网络是两种不同结构的网络,前者是有中心的集中式网络结构,而后者是无中心的网络结构。为了有效地提高蜂窝网络的数据传输容量并改善网络覆盖,国外学者提出在蜂窝网络中引入AdHoc中继节点。分析了蜂窝网络和AdHoc网络各自的优缺点,二者融合带来的优势;并介绍了两种蜂窝网中引入AdHoc中继节点的实现方案,最后提出了融合网络中的重点和难点问题,对今后的研究具有一定的启示作用。
Cellular networks and AdHoc networks are two different types of networks, the former is a centralized centralized network structure, while the latter is a non-central network structure. In order to effectively improve the data transmission capacity of cellular networks and improve network coverage, foreign scholars propose to introduce AdHoc relay nodes in cellular networks. Advantages and disadvantages of cellular networks and AdHoc networks are analyzed, and the advantages brought by the two are analyzed. The implementation scheme of introducing AdHoc relay nodes in two cellular networks is introduced. Finally, the key and difficult problems in converged networks are proposed. Future research has some enlightenment.
