Abstract

Internet of Things (IoT) embodies a vision of merging heterogeneous objects to establish seamless interaction among physical and virtual entities. IoT has given the Internet a shift from connecting networks to interconnecting the physical world. The IoT devices are capable of sensing, processing, communicating and storing the data acquired from the physical world. Most of the applications of IoT are pervasive in nature, the pervasive IoT environment poses many challenges due to constrained resources in these miniature and unattended IoT devices. This paper presents a survey of physical and virtual resource management in IoT systems. The main focus of the paper is on resource management in pervasive IoT environment with limited resources. This paper also presents a use case of IoT based Body Area Network and proposes a model for resource management in personal and community healthcare.

 Conclusions

The basic functions of an IoT device includes sensing and data aggregation, processing, storage and communication of data from the physical world to the virtual environment. For a particular application, a huge number of IoT devices are used especially in pervasive and unattended IoT applications. The pervasive IoT environments pose multiple challenges due to the resource limitations. To address the issues arising out of the resource constraints, adequate architecture is needed that permits easy connectivity and control. Considerable research has been carried out at the device level, but lack of standardization still prevails. Virtualization is one of the promising techniques which will help to optimize the available limited resources in an IoT environment. In order to optimize the resources utilization, resource allocation can play an important role in terms of distributed task allocation and work offload. Fog computing can also improve the resource management in pervasive IoT environment by local data aggregation minimizing latency, Bandwidth utilization, etc. As the number of applications is increasing, more focus has to be on the resource management with main attention on data management. Various aspects such as what to store (data size), how to store (data structure) and how to communicate the data (number of transmissions/receptions) will directly impact the management of resources in IoT environment. From the above discussions, we conclude that to optimize the use of available resources, data management and efficient resource allocation shall play a key role in pervasive IoT environments.
