Drieberg %I IEEE Computer Society %X A dense radio frequency identification network, consists of several readers located in close proximity to improve coverage and read rate. In such environment, reader to reader collision (RRC) is a common and inevitable problem. Although a number of algorithms has been proposed to mitigate these collisions, most of them require extra hardware, do not make an effective use of the network resources or they are incompatible with the current standards and regulations. This paper reviews the significant proposals for anti-collision of RFID readers, coordination in passive and dense reader environment (DRE). The short comings and incompatibilities with the state of the art standards like EPCglobal Class-1 Gen-2 are also discussed. Finally, research directions to improve the current RRC approaches are presented. © 2013 IEEE. %J 2013 IEEE 11th Malaysia International Conference on Communications, MICC 2013 %K Radio frequency identification (RFID), Anticollision; Dense-reader environment; DRE; EPCglobal; Reader anti-collision; Reader-to-reader collisions; RFID readers; State of the art, Internet of things %D 2013 %C Kuala Lumpur %T Reader to reader anticollision protocols in dense and passive RFID environment %O cited By 14; Conference of 2013 IEEE 11th Malaysia International Conference on Communications, MICC 2013 ; Conference Date: 26 November 2013 Through 28 November 2013; Conference Code:105163 %R 10.1109/MICC.2013.6805875
