ABSTRACT
Starting in May 2008, N4C is a 36 month research project in the Seventh Framework Programme (www.cordis.lu/fp7). In cooperation between users in Swedish Lapland and Kočevje region in Slovenian mountain and partners, the project will design and experiment with an architecture, infrastructure and applications in field trials and build two test beds. This document is the functional specification for Work package 3: R&D pervasive applications: E-mail, Not So Instant Messenger, Web Cache, Hikers, Hunters, Herders and Rangers Applications. It describes how Hiker’s Personal Digital Assistant (PDA) might be used in a Communications Challenged Region (CCR) where a Delay and Disruption Tolerant Networking (DTN) based infrastructure has been established. Section 1.3 describes how the requirements and the functional specifications were captured, and section 2.4 describes the methodology used for developing the applications. For WP3 the Description of Work states that quantitative review indicators are to be suggested with D3.1. The indicators the Consortium suggests are described in section 4. AUTHORS
