Design at least four broadcast protocols for a cube system with 8 nodes

Deadline is on Tuesday ,September 16 th/2014

I would like to have a design of the four broadcast protocols using a written description with the graphic representation showing how the design looks like and how information/communication happen between nodes beside the details explanation using scenarios to estimate the complexity.

Each of the designs should have an evaluation of the efficiency in the context of message complexity and round complexity.

The design should be based on a cube system with 8 nodes using

1. message-passing model

2. shared-memory model

3. mobile agent communication model

So the final work will have a total of 4 graphic designs with use case scenarios for each design to explain and calculate the complexity and efficiently of each design. The efficiency would be calculated for each design in term of message complexity and round complexity. Then decide on the best protocol among the proposed designs based on the efficiency.
