WSN中层次型拓扑控制与网络资源配置联合设计方法
A Joint Design Method of Hierarchical Topology Control and Network Resource Allocation for Wireless Sensor Networks
摘要
Abstract
Considering flow routing rate, clustering rules, and resource consumption of network bandwidth, in this paper, we propose a routing algorithm based on topology control and resource allocation in heterogeneous wireless sensor networks. The algorithm establishes a model on flow rate balance in the network layer according to the rate allocation mechanism of the cluster heads and member nodes. In the link layer, an interference model is applied to analyze the sharing spectrum behavior and the resource reconfiguration. By introducing a bandwidth scaling factor ρ, the band is re-divided into several sub-bands, aiming at maximizing the utilization efficiency of frequency band resource. Based on the cross-layer design framework, we develop a mixed-integer nonlinear programming optimization problem to obtain the optimal clustering results and resource allocation scheme, while considering the networks topology and resource allocation. We evaluate the performance in a given network topology. The results show that the proposed routing algorithm can obtain the optimum match results and the optimal route while utilizing spectrum efficiently.关键词
