In today’s world, the Internet of Things (IoT) has become more relevant owing to the growth in smart grid, smart city and smart home applications. Network sustainability is considered as a significant characteristic for IoT based applications. Wireless Sensor Network (WSN) offers such network sustainability where WSN is acted as the subnets in the IoT model. However, the multi-objectives like coverage, connectivity and energy consumption are required to improve the quality of service in IoT based WSN (IWSN) model. An appropriate optimization strategy of these multi-objective facilitates the better development of IWSN. In this paper, the Adaptive Coverage and Connectivity (ACC) scheme is proposed to attain the efficient IWSN model. It employs two underlying methodologies in which the first method provides the optimal coverage to all target objects and its mathematical model guarantees the coverage rate. The second method deals with connectivity and energy consumption of the network. The experimental results manifest that, unlike existing schemes, the proposed ACC scheme can sustain the network for a prolonged time.

在当今世界，由于智能电网，智能城市和智能家居应用的增长，物联网（IoT）变得越来越重要。网络可持续性被视为基于物联网的应用程序的重要特征。无线传感器网络（WSN）提供了这样的网络可持续性，其中WSN充当物联网模型中的子网。但是，在基于物联网的WSN（IWSN）模型中，需要覆盖，连通性和能耗等多目标来提高服务质量。这些多目标的适当优化策略有助于IWSN的更好开发。本文提出了一种自适应覆盖和连接（ACC）方案，以实现有效的IWSN模型。它采用两种基本方法，第一种方法为所有目标对象提供最佳覆盖率，而其数学模型则可确保覆盖率。第二种方法处理网络的连接性和能耗。实验结果表明，与现有方案不同，提出的ACC方案可以长时间维持网络。
