| 摘 要： | 采用有效的多信道资源分配算法可以增强网络的稳定性，提高网络的通信效率.因此提出一种适用于大规模网络的资源分配算法，既可用于静态网络，也可用于动态网络.首先根据路由树的关系，依据提出的时隙复用规则，给出节点间的时隙分配.仿真与管载数据包算法比较，在不同的通信距离下，网络的吞吐率分别提高35.7%和18.4%.在动态网络中，恢复网络通信产生的通信量与节点个数的变化有关，与总通信量的比例要小于网络节点变化的比例.

| Abstract: | Using multi-channel resource assignment increases the stability of wireless network and throughput. A resource assignment algorithm is proposed for static and dynamic large scale wireless sensor networks. According the policy to reusing link, links are assigned to nodes based on routing information. In the simulations, it improves the throughput by 35.7% and 18.4% in different communication ranges compared to packets in pipe (PIP). In dynamic networks, network traffic generated to restore traffic is related to the number of nodes. The proportion of new traffic to total traffic for networking is less than the proportion of network nodes change. |
