“…Lastly, the forwarding pointer-based mechanism [11,16] forces each node on a mobile agent's movement path to keep a forwarding pointer to the next node on the path. Thus, if a message is delivered to an agent not being at the home node, the message must traverse a list of forwarding nodes.…”

Mobile agent technology has emerged as a promising programming paradigm for developing highly dynamic and large-scale service-oriented computing middlewares due to its desirable features. For this purpose, first of all, scalable location-transparent agent communication issue should be addressed in mobile agent systems despite agent mobility. Although there were proposed several directory service and message delivery mechanisms, their disadvantages force them not to be appropriate to both low-overhead location management and fast delivery of messages to agents migrating frequently. To mitigate their limitations, this paper presents a scalable distributed directory service and message delivery mechanism. The proposed mechanism enables each mobile agent to autonomously leave tails of forwarding pointers on some few of its visiting nodes depending on its preferences. This feature results in low message forwarding overhead and low storage and maintenance cost of increasing chains of pointers per host. Also, keeping mobile agent location information in the effective binding cache of each sending agent, the sending agent can communicate with mobile agents much faster compared with the existing ones.

“…A mobile agent location management strategy is required by an agent owner to control the agent for many reasons like to stop processing being done by the mobile agent, to give some more task to the agent, to know the intermediary results of the processing being done by the agent, to change its itinerary and for agentagent communication and cooperation [1,7,9,14,21,31] . Therefore, the ability to locate mobile agents while they are migrating from one node of a network to another is of great importance in the development of agent-based applications which is a part of the location management strategy.…”

Mobile agents are processes that can be dispatched from source computer and be transported to remote servers for execution, have been widely argued to be an important enabling technology for future systems. Location management is a necessity for locating mobile agents in a network of mobile agent hosts for controlling, monitoring and communication during processing and it still represents an open research issue. The cost of location management strategies mainly depends on the cost of search and update. We concentrated on reducing the cost of update and improving the speed of processing of the agents. We proposed a location management technique applicable for multi-region environment in which mobile agent did not update its location at every migration. The technique named as Broadcasting with Search by Path Chase (BSPC). We used the tool time Petri net analyzer TINA to model, analyze and to simulate BSPC. We found that the BSPC behaves as expected and free from any deadlock. We measured the efficiency of BSPC and compared with some existing location management techniques by parametric evaluation. BSPC provided better scalability, location updating availability and interaction fault rate with theoretical considerations of network usage and network fault rate. It gave its best performance for applications of low CMR and having high migration rate of mobile agents within birth region

Abstract. Agent mobility causes reliable inter-agent communications to be more difficult to achieve in distributed agent based systems. To solve this issue, three representative agent tracking and message delivery mechanisms, broadcast-based, home-based and forwarding pointerbased, were previously proposed. However, due to their respective drawbacks, none of them is suitable for efficient delivery of messages to highly mobile agents, which move frequently between service nodes. This paper introduces an adaptive forwarding pointer-based agent tracking and message delivery mechanism to alleviate their disadvantages. The proposed mechanism allows each mobile agent to autonomously leave tails of forwarding pointers on some few of its visiting nodes depending on its preferences. Thus, it is more efficient in terms of message forwarding and location management than the previous forwarding pointer-based one. Simultaneously, it considerably reduces the dependency on the home node in agent location updating and message delivery compared with the home-based mechanism.
