研究了一种串联多跳无线传感器网络模型。每个节点周期性地在每个周期中生成分组,并且在两个相邻节点之间的有损无线链路上以存储转发的方式中继分组。为了科普大量的数据包丢失,我们以前提出了一个数据包传输调度框架,其中每个节点发送其拥有的数据包多次根据静态时隙分配,以恢复或避免数据包丢失所造成的物理条件的链路或附近的节点之间的同时传输的干扰。然而,我们假设数据包生成速率在所有节点上都是相同的,这并不总是现实的。因此,在本文中,我们加强我们的工作的情况下,异构的数据包生成率。我们推导出一个静态的时隙分配最大限度地提高在一个周期内提供所有数据包的概率。通过使用先进的无线网络模拟器,我们展示了它的有效性和有待解决的问题。
A tandemly-connected multi-hop wireless sensor network model is studied. Each node periodically generates packets in every cycle and relays the packets in a store-and-forward manner on a lossy wireless link between two adjacent nodes. To cope with a considerable number of packet losses, we previously proposed a packet transmission scheduling framework, in which each node transmits its possessing packets multiple times according to a static time-slot allocation to recover or avoid packet losses caused either by physical conditions on links or by interference of simultaneous transmissions among near-by nodes. However, we assumed that the packet generation rate is identical over all nodes, which is not always realistic. Therefore, in this paper, we enhance our work to the case of heterogeneous packet generation rates. We derive a static time-slot allocation maximizing the probability of delivering all packets within one cycle period. By using an advanced wireless network simulator, we show its effectiveness and issues to be solved.
