Simulation of RFID platform on NS-2

RFID (Radio Frequency Identification) Systems have gained popularity in recent times and have found large-scale deployment in commercial and enterprise domains. However, there is a dearth of publicly available robust simulation platforms for RFID networks. The ns-2 simulation environment is a flexible tool for network engineers to investigate how various protocols perform with different configurations and topologies. This paper describes how we extended the ns-2 framework to include support for RFID systems, and illustrates their utility with an implementation of Localized Probabilistic Algorithm (LPA) used for load balancing in RFID systems.
