The Internet of Things (IoT) has been one of the main focus areas of the research community in recent years, the requirements of which help network administrators to design and ensure the functionalities and resources of each device. Generally, two types of devices—constrained and unconstrained devices—are typical in the IoT environment. Devices with limited resources—for example, sensors and actuators—are known as constrained devices. Unconstrained devices includes gateways or border routers. Such devices are challenging in terms of their deployment because of their connectivity, channel selection, multiple interfaces, local and global address assignment, address resolution, remote access, mobility, routing, border router scope and security. To deal with these services, the availability of the IoT system ensures that the desired network services are available even in the presence of denial-of-service attacks, and the use of the system has become a difficult but mandatory task for network designers. To this end, we present a novel design for wireless sensor networks (WSNs) to address these challenges by shifting mandatory functionalities from unreliable to reliable and stable domains. The main contribution of our work consists in addressing the core network requirements for IoT systems and pointing out several guidelines for the design of standard virtualized protocols and functions. In addition, we propose a novel architecture which improves IoT systems, lending them more resilience and robustness, together with highlighting and some important open research topics.

迈向弹性无线传感器网络：虚拟化视角。

物联网（IoT）近年来一直是研究界关注的重点领域之一，其需求可帮助网络管理员设计并确保每台设备的功能和资源。通常，在IoT环境中，通常会使用两种类型的设备（受约束的设备和不受约束的设备）。资源有限的设备（例如传感器和执行器）被称为受限设备。不受限制的设备包括网关或边界路由器。由于它们的连通性，通道选择，多个接口，本地和全局地址分配，地址解析，远程访问，移动性，路由，边界路由器范围和安全性，因此此类设备在部署方面具有挑战性。为了处理这些服务，物联网系统的可用性确保即使在拒绝服务攻击的情况下也可以提供所需的网络服务，并且系统的使用已成为网络设计人员的一项艰巨而必不可少的任务。为此，我们提出了一种用于无线传感器网络（WSN）的新颖设计，以通过将强制性功能从不可靠的领域转变为可靠和稳定的领域来应对这些挑战。我们工作的主要贡献在于解决物联网系统的核心网络需求，并指出一些用于设计标准虚拟化协议和功能的准则。此外，我们提出了一种新颖的体系结构，该体系结构可改善IoT系统，使其具有更大的弹性和健壮性，并具有突出的特点和一些重要的开放研究主题。
