【摘要】：信道分配和网关部署是无线Mesh网络规划面临的重要挑战,作为影响网络性能的关键问题,传统上针对它们的研究都是独立的.为了有效结合二者规划网络,提升网络性能,提出了一种无线Mesh网络联合信道分配和网关部署策略,综合考虑了最小化链路冲突量和网关部署代价,在部署网关过程中有效地分配信道以消减无线链路间干扰.利用链路冲突量衡量网关附近节点流量聚集的特征,使用基于多目标粒子群算法来优化信道分配和选择部署网关,在信道分配和网关选择已定的情况下构建了负载均衡的转发树.仿真结果表明,相对于基于平面网络的均衡信道分配网关部署算法,该算法可以有效降低网络干扰、优化网络性能、减少节点路径长度,实现了网关间的负载均衡.
[Abstract]:Channel assignment and gateway deployment is an important challenge for wireless network planning of Mesh, as a key issue affecting the performance of the network, the traditional in their research are independent. In order to effectively combine the two planning network, improve network performance, proposes a wireless Mesh network joint channel allocation and gateway deployment strategies, comprehensive consideration to minimize the link conflict and the gateway deployment cost, effectively allocate channel to reduce inter link interference in wireless gateway deployment process. By using the link conflict measure gateway node flow characteristics gathered near, the multi-objective particle swarm algorithm based on optimal channel allocation and selection in the channel allocation and deployment of gateway, gateway selection has been set under the condition of constructing load balancing forwarding tree. The simulation results show that compared with the equilibrium distribution of planar channel gateway deployment algorithm based on network, the algorithm It can effectively reduce network interference, optimize network performance, reduce the length of node path, and realize the load balancing between gateways.
