An Agent-Based Load Balancing Approach for RFID MiddleWares

Abstract

For company to extend their RFID applications ceaselessly, the fundamental challenge is how to satisfy enterprise applications more effectively, while avoids mainframe server purchased and existed servers leave unused. It needs to decentralize work by using several RFID middlewares. So load balancing method is required for preventing centralization work in certain RFID middleware. In this paper, as a solution of tackle the challenge, we proposed a new load balancing approach based on mobile agent for RFID middlewares, which includes: information gathering policy, transfer policy, selection policy and location policy, and three agents are developed: load-info monitoring agent (LIMA) compliant to monitoring local host workload status; load-info gathering agent (LIGA) compliant to gather local and global load information; load transfer mobile agent (LTMA) compliant to choose the independent set and the appropriate scheduling scheme and implement the relocation work.
