Monitoring of RFID failures resulting from LLRP misconfigurations

Radio frequency identification (RFID) technology is becoming a pervasive technology that is used in our daily lives and in a variety of domains, especially in critical domains such as medical field and transportation systems. Several standards are specified to support the use of this technology. LLRP protocol (Low Level Reader Protocol) is one of them. It is the communication protocol between RFID readers and a client (a middleware or an end user application). It uses several XML based specifications to set up a huge number of parameters in the reader´s configuration in order to perform a correct tag inventory. Since this protocol is relatively new, there is no significant fault-tolerant mechanism that takes in consideration the protocol´s behavior. In this paper we propose an approach that monitors RFID failures resulting from misconfiguration errors of LLRP protocol by using the logging system of this protocol.
