Number : WUCSE-2006-8 2006-0101 Supporting Collaborative Behavior in MANETs using Workflows

Groupware activities provide a powerful representation for many collaborative tasks. Today, the technologies that support typical groupware applications often assume a stable wired network infrastructure. The potential for collaboration in scenarios that lack this fixed infrastructure remains largely untapped. Such scenarios include activities on construction sites, wilderness exploration, disaster recovery, and rapid intervention teams. Communication in these scenarios can be supported using wireless ad hoc networks, an emerging technology whose full potential is yet to be understood and realized. In this paper, we consider the fundamental technical issues that need to be addressed in order to introduce groupware concepts into mobile ad hoc networks. Starting with a simple workflow model, we examine the process of allocating its actions to physically-mobile agents in a manner that accommodates transient communication and runtime errors.
