Analytic modelling methodology for analysis of energy consumption for ISO 18000-7 RFID networks

Abstract

Active Radio Frequency Identification (RFID) networks consist of battery powered RFID tags. These tags have a lifetime limited by the on-board battery. Energy consumption of such a network is a critical metric. Future RFID networks are projected to continue to increase in size, eventually containing thousands or millions of nodes. Current simulation methods require evaluation of all entities resulting in extremely long execution time for large networks such as RFID networks. Simulations are a useful tool for designers to select the best design alternative for a given network. This paper presents a general framework and method that reduces the order of a given network providing a relatively simple tractable model. The energy consumption of this reduced order network can then be found quickly and efficiently. This order reduction method allows the designer to quickly analyse the design space and selects the best alternative for the network in question.
