In this paper, we investigate the need for well-suited remote communication architectures to address communication issues in mobile agent environments. We study the implication of mobility for agent architectures – specifically, ways in which the architecture may facilitate agent communication. We present an architecture for inter-agent communication suitable for remote messaging, agent monitor...

The development of software mobile agents that can solve intelligently difficult problems, represent an important research direction. There are few mobile agents described in the literature that can be considered intelligent. The difficulties in the endowment of the mobile agents with intelligence, has practical reasons related with the use of resources by the mobile agents in the network and a...

This article discusses four different applications where mobile agents cooperate with one another to accomplish a task in a network of processes. These applications range from topology discovery and distributed data structure implementation to fault diagnosis and system stabilization.

Mobile agents are an important technology in e-commerce systems and offer new possibilities for the e-commerce applications. This paper examines some mobile agent integrity protocols and proposes a new protecting protocol of mobile agent integrity. It can defend most known attacks, provides encryption transmission and route secrecy of mobile agents.

Nearly all present-day commercial intrusion detection systems are based on a hierarchical architecture. In such an architecture, the root node is responsible for detecting intrusions and for issuing responses. However, an intrusion detection system (IDS) based on a hierarchical architecture has many single points of failure. For example, by disabling the root node, the intrusion-detection funct...

Recent research has provided means by which Wireless Sensor Networks (WSN) with dynamic deadlines can make use of mobile agents for data aggregation. Lot of research has already been done with respect to using mobile agents in case of static wireless sensor networks. This paper proposes, along with brief explanation of research issues associated with applying mobile agents, two new techniques t...

Background: One of the ways for effective communication between learners and instructional multimedia content in mobile learning systems is taking advantage of characters or pedagogical agents. The present study aimed to investigate the effect of the levels of realism in mobile-based pedagogical agents on health e-learning. Methods: The s...

Mobile agents are agents that can physically travel across a network, and perform tasks on machines that provide agent hosting capability. This allows processes to migrate from computer to computer, for processes to split into multiple instances that execute on different machines, and to return to their point of origin. Unlike remote procedure calls, where a process invokes procedures of a remo...

In mobile agent systems, program code together with some process state can autonomously migrate to new hosts. Despite its many practical benefits, mobile agent technology results in significant new security threats from malicious agents and hosts. In this paper, we propose a security architecture to achieve three goals: certification that a server has the authority to execute an agent on behalf...

The mobile agent programming paradigm offers several advantages for the development of distributed systems and applications. Mobile agent dependability is a key requirement for the acceptance and future development and deployment of mobile agents. In this paper, we propose a replication scheme for mobile agents based on the group concept and associated group communication services. Group commun...
