Abstract 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 multiobjectives 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. Keywords Internet of things . Multi-objective .

1 Introduction Internet of Things (IoT) has developed as a new paradigm that consists of different physical objects, buildings and vehicles. It interconnects the objects to develop new smart services, value-added services and real-time applications. On the other hand, IoT allows to integration of several enabling technologies with different abilities like sensing, computing, monitoring, managing, storage and connectivity [1]. Communication and interconnection are considered as major challenging concerns for the efficient development of IoT. In addition, the mobility of objects is permitted in the IoT model where the establishment of rule for mobility and routing management is also addressed during the development of the IoT model [2–4].

IoT requires highly sophisticated technology for sensing the physical conditions, gathering the sensed data and to convey them to the central sink for relevant action. There are several technologies are utilized for this purpose since WSNs will be an appropriate technology for data acquisition from the physical environment [5–7]. The sensor node and sink are two key components of WSN. The major responsibility of the sensor node is to sense the physical environment, whereas the sink node handles the responsibility of gathering meaningful information from multiple s
