I need matalb code for cluster head selection in Wireless sensor networks using particle sworm optimization algorithm. Can any one share the basic code for this?

Hi Walter Roberson, my project is about energy efficiency in wireless sensor networks I WANT TO WORK ON GRAPH FORMATION to extend the coverage area and energy efficiency in wireless sensor networks. I need the MATLAB code for the optimization. Thank you

Coverage area and energy efficiency are two distinct objectives. Do you want to create a single objective that is a weighted sum of the two objectives, or do you want to study the Pareto front by running a multi objective optimization?

For any given set of model parameters, how do you want to calculate the energy efficiency, what is the formula?

These days it is common to consider having nodes with predetermined energy, and to have energy drained for transmission based partly on distance (and possibly on noise), and (less) energy drained just for staying alive or running the sensors. In such cases the local cluster heads drain their energy faster because they might have to transmit further and more often (relaying messages) so it might be necessary to change cluster heads. How do you want to calculate energy efficiency in that case, since energy now has to be measured over time?
