Abstract
The world is moving towards an interconnected and intercommunicable network of animate and inanimate objects with the emergence of Internet of Things (IoT) concept which is expected to have 50 billion connected devices by 2020. The wireless communication enabled devices play a major role in the realization of IoT. In Malaysia, home and business Internet Service Providers (ISP) bundle Wi-Fi modems working in 2.4 GHz Industrial, Scientific and Medical (ISM) radio band with their internet services. This makes Wi-Fi the most eligible protocol to serve as a local as well as internet data link for the IoT devices. Besides serving as a data link, human entity presence and location information in a multipath rich indoor environment can be harvested by monitoring and processing the changes in the Wi-Fi Radio Frequency (RF) signals. This paper comprehensively discusses the initiation and evolution of Wi-Fi based Indoor Device free Passive Localization (DfPL) since the concept was first introduced by Youssef et al. in 2007. Alongside the overview, future directions of DfPL in line with ongoing evolution of Wi-Fi based IoT devices are briefly discussed in this paper.

Summary
Human kind with the advancement of technology is striving towards intelligence in every corner of their lives from a simple light bulb to a complex smart home setup. Introduction of Internet of Things (IoT) concept became a major driver working towards the fruition of this strive. IoT is the concept of connecting animate and inanimate as well as living and non-living things via an interconnected and intercommunicable network to ease and automate the management of each connected entity [1]. With communication being the major key point for the success of IoT and having multiple wired communications around being a hindrance to daily human activities, wireless communication enabled devices became the highlight and saw further advancement in terms of energy consumption, size and cost in this era of IoT
