Models for integrating wireless sensor networks into the Internet of Things
Ubiquitous sensing and unique characteristics of wireless sensor networks (WSNs) have led to an increase in application areas such as smart parking, environmental monitoring, automotive industries and sports. In recent years, WSNs have gained more significance as the foundation infrastructure for the Internet of Things (IoT), which has greatly increased the number of connected objects with instantaneous communication and data processing. However, designing energy-efficient models for integrating WSNs into IoT is a challenging issue due to scalability and interoperability of IoT, and previous approaches designed for WSNs cannot be applied directly. This study proposes two energy-efficient models for WSNs in the IoT environment: (i) a service-aware clustering model where individual sensor nodes are assigned roles based on their service delivery; and (ii) an energy-aware clustering model.
