可靠的数据包传输是无线传感器网络(WSNs)服务质量的一个重要方面。无线传感器网络需要有针对性和可靠的数据收集方案,以提供可靠的信息。我们分析了影响可靠性的因素,并设计了可能选项的有效组合。虽然许多研究人员通过关注嵌入式通信堆栈的特定层(例如,介质访问控制(MAC)或路由层),我们提出了一个层独立的传输速率自适应方案,其中不需要额外的控制消息。我们专注于数据包丢失的避免沿着易发生故障的路径,以汇的主要目标是一个传感器节点的有效队列管理。基于某些因素(例如,应用或队列要求)节点将因此作出调整决定。我们彻底的模拟实验表明,DRAS减少了数据包丢失,并提高了数据收集过程中的能源效率的方式。
Reliable data packet transfer is an essential facet of quality of service in Wireless Sensor Networks (WSNs). WSNs require pertinent and reliable data collection schemes to provide dependable information. We analyze the factors that affect reliability, and design efficient combinations of the possible options. While many researchers have tackled this issue by focusing on particular layers of the embedded communication stack (e.g., Medium Access Control (MAC) or routing layer), we propose a layer-independent transmission rate adaptive scheme, where no additional control messages are required. We focus on packet loss avoidance along prone-to-failure paths to the sink with the main objective being the efficient queue management of a sensor node. Based on certain factors (e.g., application or queue requirements) nodes will consequently take adjustment decisions. Our thorough simulation experiments demonstrate that DRAS reduces the packet drops and improves the data collection procedure in an energy efficient manner.
