无线传感器网络（WSN）设备虽小但具有卓越的功能。无线传感器网络的每个节点都必须具有计算和处理数据以及传输和接收数据的能力。然而，WSN节点在电池容量、CPU、内存、带宽和数据安全方面的资源有限。内存限制意味着 WSN 设备无法存储大量信息，而 CPU 限制使其运行缓慢，有限的电池容量使其运行时间较短。此外，网络收集和处理的数据面临着真正的安全威胁。本文介绍了一种自适应资源和安全框架 (ARSy)，它能够适应无线传感器网络中的工作负载、安全要求和可用资源。工作负载适应旨在保持WSN的资源可用性，而安全适应则平衡安全级别与资源利用率。该解决方案根据系统的工作负载提供资源，并调整安全级别以节省资源，并使 WSN 设备更高效地工作。
View of wireless sensor network (WSN) devices is small but have exceptional functionality. Each node of a WSN must have the ability to compute and process data and to transmit and receive data. However, WSN nodes have limited resources in terms of battery capacity, CPU, memory, bandwidth, and data security. Memory limitations mean that WSN devices cannot store a lot of information, while CPU limitations make them operate slowly and limited battery capacity makes them operate for shorter periods of time. Moreover, the data gathered and processed by the network face real security threats. This article presents an Adaptable Resource and Security Framework (ARSy) that is able to adapt to the workload, security requirements, and available resources in a wireless sensor network. The workload adaptation is intended to preserve the resource availability of the WSN, while the security adaptation balances the level of security with the resource utilization. This solution makes resources available on the basis of the workload of the system and adjusts the level of security for resource savings and makes the WSN devices work more efficiently.
