Apart from radio frequency identification (RFID) sensors, a radar-based sensor for IoT applicatioin is introduced. It is a proposed technology that is capable of providing not only information to the IoT system but in addition helps to secure the smart environment from relatively intending stealth objects vulnerable to the environment. This paper verified the feasibility of integrating radar system as a sensor device to serve as a source of information for a successful IoT deployment. The paper further highlights some IoT architectures presented by various researchers, given preference to sensor layer of the IoT architecture.

INTRODUCTION Internet is continuously evolving from a human-to-machine (H2M) base communication to machine-to- machine (M2M) communication system [1] and [2]. It was estimated that by the year 2020, about 30 billion devices were expected to be deployed across the world [3]. Internet of things (IoT) is a synergetic approach of cascading telecommunication, hardware and software engineering, informatics as well as social sciences to work as one entity [2], for interoperability of heterogeneous devices. In the face of wireless communication systems, tremendous achievements were recorded with smart homes, which can be seen as the advent of IoT when multihop network interconnecting a smart environment was extended to represent a virtual world [4]. In spite of the foreseen IoT benefits like learning enhancement, e-health among others, there exist a posing threats like trust guarantee, compromise of security and privacy and other challenging factors derailing the acceptance of the emerging worldwide network [5]. IoT creates a platform for intelligent interaction between real time activities [6], and making the Internet more immersive and pervasive [7]. Smart algorithms execution for intelligent interactions with other things in the Internet is one basic IoT feature achievable via information consumption. IoT involved transforming a real life activity into virtual or rather digital world. The IoT emerges among the hot topics focused by both researchers, industries [8], and government agencies. [1] reported how European and American organizations with other multinational companies were involved in the design and development of IoT for achieving multiple benefits. Very powerful automated services in the field of security, e-health and e- governance were among the various services that can be achieved through a successful implementation of the IoT. Objects connected to IoT environment usually provides a M2M communication platform through sensors and actuators. Information retrieved from the connected objects can be through either or a combination of RFID, wireless sensor networks (WSN), gateway server, middleware, internet protocols (IPs). M2M connectivity can also be achieved via global positioning system (GPS), geographical information system (GIS), smart objects and RFID. Through IoT, objects can be sensed and controlled remotely via the existing network facilities [7]. Identification and tracking technologies as a function of IoT [8] is performed by RFID, barcode and intelligent sensors thus, radar can therefore serves as a good candidate for such application as well due to its similar characteristics.
