论文摘要

我们通过将信号对干扰加噪声比(SINR)作为干扰模型来研究多个网关无线网络网络中网络实用性最大化的问题。目的是跨层设计,该设计考虑了联合费率控制,交通分裂,路由,调度,链接率分配和功率控制,以制定网络实用程序最大化问题。由于此问题在计算上是复杂的,因此我们提出了基于差分积压列表作为亚最佳解决方案的关节动态网关选择,链路分配和功率控制(JGRP)算法。该算法首先构建初始网络拓扑,然后在每个时间插槽中同时确定每个交通流的发电率和目标网关。该算法的另一个主要任务是每个时间插槽中的关节路由,调度,链接速率分配和节点功率分配。此外,为了提高公平性,我们提出了一些新的参数,而不是JGRP算法中的差异积压。仿真结果表明,使用JGRP算法中的建议参数可提高吞吐量和视图延迟点的公平性。

We investigate the problem of network utility maximization in multiple gateways wireless mesh networks by considering Signal to Interference plus Noise Ratio (SINR) as the interference model. The aim is a cross layer design that considers joint rate control, traffic splitting, routing, scheduling, link rate allocation and power control to formulate the network utility maximization problem. As this problem is computationally complex, we propose the Joint dynamic Gateway selection, link Rate allocation and Power control (JGRP) algorithm based on the differential backlog as a sub-optimal solution. This algorithm first constructs the initial network topology, and then in each time slot, determines the generation rate and destination gateway of each traffic flow, simultaneously. The other main task of this algorithm is joint routing, scheduling, links rate allocation and node power allocation in each time slot. Moreover, for improving the fairness, we propose some new parameters instead of the differential backlog in JGRP algorithm. Simulation results show that using the proposed parameters in JGRP algorithm improves fairness from throughput and delay point of views.
