Abstract

Many researchers are devoting attention to the so-called “Internet of Things” (IoT), and wireless sensor networks (WSNs) are regarded as a critical technology for realizing the communication infrastructure of the future, including the IoT. Against this background, virtualization is a crucial technique for the integration of multiple WSNs. Designing virtualized WSNs for actual environments will require further detailed studies. Within the IoT environment, physical networks can undergo dynamic change, and so, many problems exist that could prevent applications from running without interruption when using the existing approaches. In this paper, we show an overall architecture that is suitable for constructing and running virtual wireless sensor network (VWSN) services within a VWSN topology. Our approach provides users with a reliable VWSN network by assigning redundant resources according to each user’s demand and providing a recovery method to incorporate environmental changes. We tested this approach by simulation experiment, with the results showing that the VWSN network is reliable in many cases, although physical deployment of sensor nodes and the modular structure of the VWSN will be quite important to the stability of services within the VWSN topology.

Highlights

For the future Internet of Things (IoT) environment, the effective integration of various types of networks will be an important consideration
We showed that the virtual wireless sensor network (VWSN) topology constructed by our proposal is robust against node removal on both connectivity and path length in our previous work [13]
We evaluate the adaptivity of a VWSN topology constructed from the network, which is composed of two sensor networks and one wired link

Summary

Introduction

For the future Internet of Things (IoT) environment, the effective integration of various types of networks will be an important consideration. In addition to the co-existence of wired and wireless links, domains may involve sensor nodes and actuator nodes from multiple vendors. Applications running over such mixed networks will make different demands of the network, such as locational information or other node-specific information. To realize the IoT environment, wireless sensor networks (WSNs) will be a crucial technology to allow collecting and acting on environmental information. WSNs will be integrated into future communication infrastructure [1]. Networks are considered to be constructed independently to provide service within a local area
