Compared to traditional middleware, adaptive middleware enables modification of the behavior of distributed applications in response to some changes in functional requirements or operating conditions. RFID applications in particular have grown widely and are used in many purposes such as supply chain management and ubiquitous computing. Implementing adaptive characteristic in RFID middleware will increase the capability of adaptation to specific environment involving different reader/tag, different applications, and different platforms. Based on an extensive study conducted, standard features that reflect the functionalities of RFID middleware and adaptive features that represent the non-functionalities of RFID middleware have been identified. Multi-reader detection indicates one important feature in adaptive RFID middleware as it offers flexibility in deployment of various manufactured-readers. This paper discusses the successful implementation of multi-reader detection feature in the proposed adaptive RFID middleware.

1. Introduction
Radio Frequency Identification (RFID) is a technology that identifies a tagged object using radio frequency comprising of a reader, a tag and host computer that captures, filters, saves and presents the information from the tag. RFID technology changes the bar code system with several advantages, such as it does not require the tag to be in line-of-sight, it allows multiple tags to be read simultaneously, it can work in

various range, from short (2 cm) to long range (15 m). That is why, RFID applications grow widely and have been used in many purposes such as medicine [2], aeronautics [3], construction and maintenance of oil facilities [4], automotive [5], and retail [6]. Middleware is a software layer that connects and manages application component running on distribution host [7]. Middleware hides and abstracts many of the complex details of distributed programming from application developers [8,9]. Implementing middleware on RFID application has several benefits [8], such as improving the network communication, coordination, reliability, scalability, and heterogeneity. Thus RFID middleware has special purpose to collect a large volume of raw data from heterogeneous RFID environment, filter them and summarize them into meaningful information and deliver the information to application services [10]. Using traditional middleware in RFID application has a limitation in capabilities to support adaptation. Different reader, different platform and applications are several factors that influence the operation of RFID Middleware system. Therefore adaptive features that represent the non functionalities of RFID middleware have evolved from traditional middleware [11]. One of important aspects in adaptive RFID middleware features is to deal with multi readers. This issue has been investigated by Bo et. al [12] and the reader adapter component has been proposed. Reader adapter could communicate and interact with multi readers from different manufacturers. This paper...
