提高网络的整体性能一直是无线多跳网络研究的重点问题,在以多信道、多接口环境搭建的无线多跳网络中,可以通过有效的信道分配策略来提升网络性能.提出一种基于小世界特性的无线多跳网络信道分配策略,通过DLCC策略利用小世界特性先优化网络的拓扑结构,再根据网络链路的局部介数以及链路预冲突系数,利用CALB信道分配算法进行信道分配.实验表明,该策略能有效地降低网络链路之间的冲突,提升网络的性能.
To improve the overall performance of the network has been a key issue in the research of wireless multi-hop networks. In a multi-channel and multi-interface wireless multi-hop network, an effective channel allocation strategy can be used to improve network performance. Characteristics of the wireless multi-hop network channel allocation strategy, the DLCC strategy using the characteristics of the small world to optimize the network topology, and then according to the local link of the network link and link pre-conflict coefficient, the use of CALB channel allocation algorithm for channel assignment. It shows that this strategy can effectively reduce the conflicts between network links and improve the network performance.
