Multidimensional codesign is a recently proposed paradigm for integrating different system dimensions in sensor networks. Examples of such dimensions are logical and physical mobility, continuous and discrete transitions, deterministic and random evolutions and features resulting from their interaction, like deterministic and stochastic hybrid behaviours. In this paper, we propose a unifying co...

Thomas Bolander: Logical Theories for Introspective Agents Artificial intelligence systems (agents) generally have models of the environments they inhabit which they use for representing facts, for reasoning about these facts and for planning actions. Much intelligent behaviour seems to involve an ability to model not only one’s external environment but also oneself and one’s own reasoning. We ...

Recently, a model multi-agent e-commerce system based on mobile buyer agents and transfer of strategy modules was proposed. In this paper a different approach to code mobility is introduced, where agent mobility is replaced by local agent creation supplemented by similar code mobility as in the original proposal. UML diagrams of agents involved in the new approach to mobility and the augmented ...

In the past few years, we have witnessed the growth in availability of mobile computing devices, such as mobile phones, personal digital assistants (PDAs), laptop computers and the like, combined with the advent of new wireless networking systems, such as 802.11b, Bluetooth, and GSM/GPRS. Users of such devices demand access to networked information and services at all times and locations, and, ...

A framework is described that can be used to build and test application-level software for wireless mobile computing. It emulates the physical mobility of wireless devices by using the logical mobility of software-based emulators of the devices and target software. Since each emulator is implemented as a mobile agent, it can dynamically carry the target software to each of the sub-networks to w...

Mobile computing devices, such as personal digital assistants and mobile phones, are becoming increasingly popular, smaller, more capable and even fashionable personal items. Combined with the recent advent of wireless networking techniques, users are equipped with mobile devices of significant computational abilities, which are able to wirelessly access information by dynamically connecting to...

This paper proposes a framework for which agents can be used for providing web services to mobile users. It describes a set of obliging agents distributed over different sites that work together to provide web services for mobile users. Mobile agents are programs dispatched from a client mobile device to the server to achieve a task. This is much more dynamic than client-server paradigm in whic...

Because of its loose coupling between event producers and consumers, publish/subscribe (pub/sub) middleware has many advantages when implementing systems for spontaneous, ad-hoc, pervasive applications. One main aspect of such applications is device mobility, but unfortunately, most of the current pub/sub systems do not adequately support mobile clients. Mobility has two orthogonal aspects: phy...
