The Mobile Agent (MA) paradigm proposes several attractive solutions to deal with the problems of networkcentric programming. Despite the availability of several MA platforms, there are still only a few MA-based distributed services. The paper claims that the lack of interoperability is one

Abstract. The paper presents one solution that is adopted in an implementation of workflow management systems using mobile agents. Mobile agents occasionally need additional services that are implemented as stationary agents (for example, mail service, ftp service, database connectivity

. An alternative scheme is required to support efficient web access. On the other hand, personalization plays an important role in the tailored access to the Web contents and services. In this paper, we propose a scheme for a mobile agent system that provides frequently accessed browsing link sequence with its

Abstract: The main challenge when deploying mobile agent environments pertains to security issues concerning mobile agents and their executive platform. This paper proposes a secure protocol which protects mobile agents against attacks from malicious hosts in these environments. Protection is based

In a recent Physical Review Letters paper, Vicsek et. al. propose a simple but compelling discrete-time model of n autonomous agents fi.e., points or particlesg all moving in the plane with the same speed but with dierent headings. Each agent's heading is updated using a local rule based

Emerald is an object-based language and system designed for the construction of distributed programs. An explicit goal of Emerald is support for object mobility; objects in Emerald can freely move within the system to take advantage of distribution and dynamically changing environments. We say

We present the a-calculus, a calculus of communicating systems in which one can naturally express processes which have changing structure. Not only may the component agents of a system be arbitrarily linked, but a communication between neighbours may carry information which changes that linkage

Future computing environments will free the user from the constraints of the desktop. Applications for a mobile environment should take advantage of contextual information, suach as position, to offer greater services to the user. In his paper, we present the Cyberguide project, in which we

For such self-organizing infrastructures as mobile ad hoc networks , envisioned to operate in an open, collaborative, and highly volatile environment, the importance of secu- rity cannot be underrated. The provision of comprehen- sive secure communication mandates that both route dis- covery

This paper presents a unique real-time obstacle avoidance approach for manipulators and mobile robots based on the artificial potential field concept. Collision avoidance, tradi-tionally considered a high level planning problem, can be effectively distributed between different levels of control, al
