Evaluation of Performance in IPS Using RSS and Directional Antenna

Abstract

In indoor positioning system, RFID is a wireless communication technique which identifies the position of a mobile node by analysis of data. Radio location using signal strength is a popular method though RSS based systems are easy to implement, but the accuracy is relying upon environment and distance. These systems have limited network capacity due to high interference and the low spatial reuse when they does not considered directivity for transmission. In such system antennas can be used to boost the strength of wireless networks. The design of antenna can affect the gain in throughput and deduction in power consumption. In RFID based system complexity become a key issue as number of mobile nodes gets increased with their dynamic behaviour. So the proposed system is introduced the combination of RSS with directional antenna to enhance the QoS in terms of efficiency, jitter, accuracy, delay, mean, deviation and throughput with respect to scalability. Improvement of these parameters with directional antenna over omni-directional is demonstrated using network simulator.
