Abstract

The Internet of Things connects millions of devices in the areas of smart cities, e-health, transportation, and the military to fulfill a variety of human needs. To offer these services, a large amount of data must be transmitted to the IoT network servers. But the node processing power, buffer size, and server capacity limitations on IoT networks have a negative influence on throughput, latency, and energy consumption. Additionally, the IoT network’s performance is decreased by congestion caused by the high network traffic that results from the high volume of data. In order to handle congestion challenges in IoT networks, unique congestion control strategies—such as the queue management strategy—must be created. In this study, a novel Priority Queue-based Token Bucket Algorithm (PQTBA) is suggested as a means of controlling congestion in IoT networks. The PQTBA uses a preemptive/non-preemptive technique with a discretionary rule to categorize network traffic into priority groups in accordance with real-time requirements. Our proposed work performs con-siderably better than the most recent techniques in terms of throughput, packet loss ratio, and energy consumption.
PQTBA:基于优先队列的物联网网络拥塞控制令牌桶算法
物联网连接了智慧城市、电子医疗、交通和军事领域的数百万台设备,以满足人类的各种需求。为了提供这些服务,必须将大量数据传输到物联网网络服务器。但物联网网络中的节点处理能力、缓冲区大小和服务器容量限制会对吞吐量、延迟和能耗产生负面影响。此外,由于大量数据导致的高网络流量导致的拥塞导致物联网网络的性能下降。为了应对物联网网络中的拥塞挑战,必须创建独特的拥塞控制策略,例如队列管理策略。在这项研究中,提出了一种新的基于优先队列的令牌桶算法(PQTBA)作为控制物联网网络拥塞的手段。PQTBA采用抢占/非抢占技术,并结合自由裁量规则,根据实时需求将网络流量划分为多个优先级组。我们提出的工作在吞吐量、丢包率和能耗方面比最新的技术要好得多。
