In this paper, we propose a Logical Location Map to solve the problem of decreased accuracy of indoor physical location in the indoor environment. A lot of studies have been performed to reduce the indoor physical location errors. However, location errors still occur with changing environment, more research is needed. This paper aims to obtain […]

In this paper we describe an energy efficient protocol for active radio frequency identification (RFID) tags complying with the standard. The energy efficiency is a key requirement for the wider acceptance of the active RFID systems that use battery constrained tags. The existing active RFID protocols try to reduce energy consumption of tags by putting […]
