Atomic Mobile Agent Group Communication

This paper proposes an atomic mobile agent group communication protocol to achieve all the following requirements existing protocols couldn't address due to their respective limitations. This protocol improves scalability by enabling each mobile agent to choose only a few among its visiting nodes as agent location manager depending on its preferred policies such as location updating and message delivery costs, security, network latency and topology, inter-agent communication patterns, etc.. Second, to guarantee agent communication reliability despite agent location managers's failures, it allows each mobile agent's location information to be replicated in an effective way to preserve its scalability to a maximum. Also, it has messages destined to an agent group to be reliably delivered to its surviving group members in the same order. Lastly, each sending agent's agent group location cache significantly allows message delivery time to the targeted mobile agents to be shortened and message forwarding load imposing on agent location managers to decrease.
