Optimal deployment strategy of RFID networks using Tabu search mechanism

This work proposes a novel reader deployment mechanism for RFID applications used in daily life activities. Two aspects of the proposed mechanism are discussed: optimizing RFID reader deployment and adjusting reading speed to minimize reader collision. Tabu search strategy is used to find the better locations of deploying readers. Reader deployment performance is analyzed in terms of deployment cost, reader collision, system throughput and hit-miss ratio. Compared to traditional dense mechanisms, the proposed mechanism has a 36% lower deployment cost and a 34% lower average collision rate with only minor sacrifice of system throughput or hit-miss ratio.
