Bluetooth Protocol in Internet of Things (IoT), Security Challenges and a Comparison with Wi-Fi Protocol: A Review

Abstract

There has been a growing interest, over the past few years, in the Internet of Things (IoT), cutting across various industries, ranging from public transport to academia etc. This paper gives an overview of the current state of Bluetooth and Wlan(Wi-fi) technology. This study covers some facets aside from a brief introduction to the principles of the technology, major current and envisaged fields of application. It addresses an overview of the technologies in terms of services. The open communications environment makes wireless transmissions more vulnerable than wired communications to malicious attacks, including both the passive eavesdropping for data interception and the active jamming for disrupting legitimate transmissions. Therefore, this paper is motivated to examine the security vulnerabilities and undercurrents imposed by the inherent open nature of wireless communications.
