【摘要】 信道分配问题(CAP)是无线蜂窝网中的一个重要方面,它根据呼叫请求对频率进行分配,同时使得整个网络所需的频率最少。文中描述了一个有效的频率分配策略(聚结CAP),它源于多重染色算法,所用模型基于移动通信网络中常用的三角网格图。同时,该方案是分布式的,即网络中每个基站只需要和其邻接基站之间交换部分信息,即可得出自身的频率分配方案。更多还原

【Abstract】 The Channel Assignment Problem(CAP)is an important aspect of cellular network,it is required that frequencies must be assigned to call requests and the frequency number of the whole network is minimized.An efficient frequency assignment strategy(coalesced CAP)is introduced,it is derived from a multicolouring algorithm.Its model is based on a triangular lattice-mobile communication network.The strategy is distributed:each cell server will need only a limited exchange of information with cells in its proximity to make decisions on its frequency assignment.更多还原
