Tactical cloudlets are forward-deployed, discoverable, virtual-machine-based servers that can be hosted on vehicles or other platforms to provide a computation offload and data staging infrastructure for mobile devices in the field. Because of the mobility of cloudlets in the field, as well as dynamic missions, a mobile user of a cloudlet might need to migrate active capabilities (computation and...
When establishing communication between two nodes, identification, authentication, and authorization provide the information and assurances necessary for the nodes to trust each other. A common solution for establishing trust between two nodes is to create and share credentials in advance, and then use a third-party, online trusted authority to validate the credentials of the nodes. However, the characteristics...
Cyber-foraging is a technique for dynamically augmenting the computing power of resource-limited mobile devices by opportunistically exploiting nearby fixed computing infrastructure. Cloudlet-based cyber-foraging relies on discoverable, generic, forward-deployed servers located in single-hop proximity of mobile devices. In particular, we define tactical cloudlets as the infrastructure to support computation...
Energy efficiency is a primary concern for the ICTsector. In particular, the widespread adoption of cloud computing technologies has drawn attention to the massive energy consumption of data centers. Although hardware constantly improves with respect to energy efficiency, this should also be a main concern for software. In previous work we analyzed the literature and elicited a set of techniques for...

Handheld mobile technology can help disaster relief workers and soldiers in the field with tasks such as speech and image recognition, natural language processing, decision-making, and mission planning. However, these applications are computation-intensive, take a heavy toll on battery power, and often rely on good connectivity to networks, limiting their practical usefulness in a crisis. This paper...
XMPP (XML Messaging and Presence Protocol), also known as Jabber, is a popular instant messaging protocol that uses XML streams for communication. Due to it's high extensibility, XMPP is very easy to adapt to other uses than instant messaging. Furthermore, announcing of presence state makes it ideal for highly volatile environments. This paper outlines the use of XMPP for a grid-like computation environment...
