Clustering schemes have been adopted as efficient solutions to prolong network lifetime and improve network scalability. In such clustering schemes cluster ratio is represented by the rate of the number of cluster heads and the number of total nodes and affects the performance of clustering schemes. In this paper, we mathematically analyze relation between cluster ratio and path loss in a cluster and an optimal cluster ratio is developed to provide promising channel and minimize packet loss. We examine its performance through a set of simulations. The simulation results show that the proposed optimal cluster ratio effectively guarantees packet reception rate in WSN.
