Cross-layer Congestion Control and Routing Design for Wireless Sensor Networks:Distributed Newton Method
摘要
Abstract
Wireless sensor networks have a wide range of extensive applications, and their performances are strongly dependent on routing and congestion control. Therefore, in this paper we address cross-layer optimization of congestion control and multi-hop routing to achieve network utility maximization for wireless sensor networks sub ject to link capacity and node power constraints. Considering that dual subgradient algorithm has a very slow convergence and large amount of information exchange, we design a distributed Newton method with quadratic convergence performance to maximize the network utility. We use matrix splitting technique to distributedly solve Newton dual direction through single-hop information exchange. Extensive simulation shows that distributed Newton algorithm converges faster than the dual subgradient algorithm.关键词
