摘要:

我们考虑一个数据聚合的无线网络,其中所有的节点都有数据发送到一个单一的目的地节点,汇。我们考虑一个线性放置的节点与汇在一端。节点直接与接收器通信(单跳传输),我们假设节点由中央调度器(可能是接收器)一次调度一个。无线节点的功率有限,我们的网络目标(公平的概念)是最大限度地提高节点的最小吞吐量的节点功率约束。在这项工作中,我们考虑网络设计,允许适应节点传输时间,节点传输功率和节点的位置,并研究跨层的策略,寻求最大限度地提高网络吞吐量。使用模拟,我们表征了不同的策略的性能,并评论其适用于各种网络场景。

英文摘要:

We consider a data aggregating wireless network where all nodes have data to send to a single destination node, the sink. We consider a linear placement of nodes with the sink at one end. The nodes communicate directly to the sink (single hop transmission) and we assume that the nodes are scheduled one at a time by a central scheduler (possibly the sink). The wireless nodes are power limited and our network objective (notion of fairness) is to maximize the minimum throughput of the nodes subject to the node power constraints. In this work, we consider network designs that permit adapting node transmission time, node transmission power and node placements, and study cross- layer strategies that seek to maximize the network throughput. Using simulations, we characterize the performance of the dif- ferent strategies and comment on their applicability for various network scenarios.
