One of the most important problems studied in wireless sensor network applications is the collaborative processing among sensor nodes in order to compensate for each other’s sensing and computing capabilities and to tolerate faults. The client/server based paradigm and the mobile agent based paradigm are two popular computing models used in collaborative processing. One of the most challenging ...

This paper presents an application of Hierarchical Transition Network (HTN) planning to a squad-based military simulation. The hierarchical planner produces collaborative plans for the whole squad in real time, generating the type of highly coordinated behaviours typical for armed combat situations involving trained professionals. Here, we detail the extensions to HTN planning necessary to prov...

This work presents the development of a multiuser virtual environment in support of crisis management planning activities. Coupling ongoing work in activity representation with analysis of the crisis action planning domain, an extensible domain ontology was developed. Studying the domain, several challenges became apparent: (1) the need to support extensive dynamic and distributed collaboration...

The field of collaborative health planning faces significant challenges due to the lack of effective information, systems and the absence of a framework to make informed decisions. These challenges have been magnified by the rise of the healthy cities movement, consequently, there have been more frequent calls for localised, collaborative and evidence-driven decision-making. Some studies in the...

ABSTRACT: As the architecture/engineering/construction (AEC) industry proceeds in the direction of digitalisation, computer supported collaborative work (CSCW) enhanced by building information modelling (BIM) becomes realistic for multidisciplinary collaboration in construction. Networked virtual reality (VR) supported by BIM servers, though showing great potentials in connecting multidisciplin...

Today, achieving collaborative tactical planning on the battlefield presents a significant challenge in the new DoD Net-Centric systems-of-systems (SoS) and the futuristic integrated and adaptive C4ISR systems-of-systems. The primary reason is that in a Net-Centric environment both manned and unmanned heterogeneous platforms and robotic systems must work side-byside with the warfighters, but th...

In this paper we describe the results of a study which compares explicit synchronous collaborative web search with searching the web individually when users are utilizing the web for the purpose of social planning tasks, in specific travel planning. We explore both co-located and distributed collaborative search within groups of two and three participants. The distributed collaborative search i...
