I am working on Energy Efficiency of Cooperative Communication in Cellular Networks, i want to compare the three scenarios:1. direct Transmission, 2. Using Single Relay , 3. Multi Relay Transmission.

I am Working on Energy Efficiency of Cooperative Communication in Cellular Networks, i need to compare the energy consumption of three Scenarios, 1. Direct Transmission, (Without Relay) 2. Using Single Relay, and 3. Multi Relay Transmission. help me please? thanks

The concept of cellular radio is based on the cell, which was decided to be a hexagon(6 sided). This is an approximation to a circular cell. The intuitive cell shape would be a square, but this is extremely hard to do with aerials and would be expensive, if it is possible to do at all.
A big transmitter can have a hexagon radiation patter. Many small stations can have an overall hexagonal radiation pattern. A big station with one relay would have a radiation pattern like a figure eight (8), with unequal hexangonals, so when you try to tessellate them, they just will not fit neatly together.
A better way for your research to go would be to consider an area and cover it with a big transmitter, then with transmitters of 1/10 of that power, then transmitters of 1/100 of the big transmitters power.
The energy costs for small stations, are small, but you still need a fibre optic cable to get the signals into the national network. You also need planning permission to erect the mast which would be increasingly difficult if a neighboughood was peppered in masts.
