Abstract


Mobile Agent technology in distributed systems, wireless networks , e-commerce and other fields have been applied , the advantage is that it gives on the Internet Intelligent Agent autonomous mobile and execute and complete the tasks specified by the user . Mobile Agent has the mobility, autonomy can save network bandwidth and reduce the communication amount of data transferred between nodes . Mobile Agent-based third-generation e-commerce systems , e-commerce technology to overcome the traditional shortcomings , has a broad application prospects. Mobile Agent communication mechanism is one of the key technologies of Mobile Agent is the basis for implementing distributed applications . In a distributed environment, because Agent autonomous mobile may cause communication failure or communication chase, while the existing communication mechanisms in communication efficiency , reliability, communication deficiencies , not better meet the needs of distributed applications . For domestic and Mobile Agent communication mechanism existing shortcomings in the mailbox -based communication mechanism based on an improved communication mechanism LMCP. In the communication process through Locator node location management , the use of Agent predict the amount of information received by mail migration decision-making , reduce communication overhead and improve communication efficiency , and fault-tolerant mechanisms proposed LMCP strategy . In LMCP mechanism proposed mailbox migration path Locator node concept, location management communication and information transfer into two parts , and gives the location management and information transfer detailed implementation processes. Agent to receive information simultaneously defines the number of thresholds , Agent forecast to decide whether to carry through a number of mailboxes migrated together , and gives algorithm steps . In order to improve the reliability of LMCP mechanism proposed Locator node fault tolerant load balancing mechanism, fault tolerance into failure detection , failover , load balancing three modules , each module gives the algorithm steps . Finally, the performance of LMCP mechanism simulation analysis to Aglet and Java as an experimental platform , and related work in the ARP mechanism of a comparative analysis , and fault-tolerant mechanisms LMCP status information arrival time dynamic correction value and the fixed correction value the results were compared. Experimental results show that , LMCP mechanism to enhance the adaptability , a better solution to the problem of communication failure , the communication overhead is smaller , the communication efficiency.
