Improved Indoor Positioning Using RSS and Directional Antenna Integrating with RFID and Wireless Technology

In today's era finding the location and navigation of an object is essential for many reasons. The primary reason is locating the object, and navigation helps systems to make decisions faster. Secondary reason is we may detect fault and posses faster processing and operation. Another side of development and research is for cost-effective techniques involving indoor and outdoor systems. Many researchers are working on indoor positioning and developing lightweighted solutions using radio frequencies. Managing and monitoring radio frequencies in an indoor system have physical barriers; they also have some technological limitations where we can provide solutions. The solutions for indoor localization and tracking are GPS signal, Bluetooth, infrared, RFID, and wireless LAN. All these radio frequencies deal with a crucial issue of gaining RSS (Received Signal Strength). In this work, we are focusing on RFID-based indoor environment where RSS is our main attention, we also target on gaining efficiency and accuracy, stability, robustness. The proposed algorithm of this work is mainly targeting with directional antenna by which we can overcome the physical and other barriers of radio frequency. These kinds of indoor environments such as health care, loyalty management system, automatic parking allotment system, tracking services for older people, or customers inside living communities, mobile robot, logistics system, etc., can be facilitated using directional antenna and RFID tagging for navigation indoor positioning.
