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.
