Designing a WSN involves taking into account two most important design criterions. One is achieving the energy optimization and other is enhancing the network longevity. Particle Swarm Optimization (PSO) technique is an efficient protocol which is capable of achieving these deign goals. Now PSO algorithm can be designed either having a Single Cluster Head or Double Cluster Heads. This paper deals with the choice to be made out of these algorithms depending upon the Wireless Sensor Network (WSN) scenarios. PSO being a heuristic technique, it is very important to choose the efficient method in order to achieve an improved network lifetime along with reduction in energy consumption.
