On Iham Traditional Rfid Middleware Performance Comparison

RFID Middleware, as the centrum of RFID application, is attracting more and more attention, while the research of the RFID industry is extending and the scope of its application is spreading from manufacture, logistics, medical treatment, transportation, retails as well as national defence fields etc. RFID Middleware, also called RFID Edge Server, plays an important role which abstracts tag data, and then forwards them to the back-end server system. Currently, in order to extend the related RFID technology and its application, besides these industrial specifications, there are also a lot of industrial RFID middleware provided by many famous companies and institutions. Still, as the traditional RFID Middleware solutions, most of them cast so many computers as well as software to keep the degeneration of system function. That means the waste from CPU load and Physical Resources are both amazing, though they are able to manage the related operation to work continuously. In such condition, the research group in SAP produced a new generation RFID Middleware product, intelligent high available middleware, which is just software at current stage, but a distributed system, in late 2008. It attracted most attention from the experts in related fields. On the other side, it also points out a new development orientation for the future RFID Middleware.In this paper, we establish a simulation model on which a fair performance comparison between IHAM and traditional RFID middleware, including their CPU utilization, memory utilization, workload, response time areas etc. The performance parameters of IHAM and traditional middleware are compared in terms of common performance metrics. As the advantage and characteristic, such paper represents the following things: 1. How to abstract the digital model from RFID real-runtime condition to compare the existent RFID middleware system in a fair mode. Besides that, both Reader Emulator and Application Emulator are set to benefit our research. 2. Some essential technology, CHAM and QNM, is also utilized to analyze the various keys in the model stated above. 3. In the final stage, the new generation IHAM and traditional RFID middleware are compared with all-sided elements for the first time, by PTT panel. The results illustrate that the IHAM and traditional middleware have their own advantages in a set environment. Compared with the traditional distributed system middleware which holds more CPU resources, the IHAM, however, is able to finish more operation with less response time, less memory utilization, less CPU utilization. However, so far, the fuzzy loading is a little high. How to perfect such system performance and attemper system resources more effectively is a serious issue we have to face. Still, in a word, in common situation, the IHAM performs much better than traditional ones. After all, the IHAM offers more integrative application which meets our need. Moreover, it is possible to adjust the utilization rate of physical resources for IHAM to realize a better performance.
