Initial Data-LINK layer Model and Simulator

Summary
This model takes account of the preliminary outputs of the work on D5.1 to frame the task of developing the Link layer model. This model will be sufficiently flexible to support a sensitivity analysis of the main inputs and thus be extensible to support more complex behaviours. A secondary output, more a concern of WP7 than WP5, will be input to standards, where this deliverable will play a major part.
