| 摘 要： | 在无线电网络中,邻近的地理区域内用同一个频道的用户过多就会引起无线电通信的拥塞.增加频道负荷约束,限制统一时间内用相同频道的用户数量来控制这一现象.给出了具有频道负荷约束的专用移动无线电网络问题的整数线性规划,设计了求解特殊网络的具有频道负荷约束的频道分配问题的多项式时间算法.

| Abstract: | Radio traffic congestion occurs in a radio network when too many users simuhaneously transmit on the same channel within close geographical proximity. Such congestion can be prevented by imposing channel loading constraints, which restrict the number of users that can operate using the same channel at one instance in time. An integer programming formulation for channel assignment problem with channel loading is presented and polynomial time algorithms are designed for some special radio networks in this paper. |
