In this research paper, a simulation model is proposed which can be used to evaluate the performance of LEACH protocol in realistic noise-prone WSN environment. In this model, the noise-level is represented by the probability of reception (pr) of packets. When pr is one the network environment is considered noise-free and all packets sent are received and when pr is less than one the environment is considered noise-prone. The noise effect is specified by generating a uniform random number U; if U is less than pr the packet is delivered successfully to the receiving node, otherwise, packets are dropped. The proposed simulation model was implemented utilizing Python programming language. The effect of various noise levels on the performance of homogeneous LEACH algorithm was investigated for different network metrics. An energy model incorporating noise was derived analytically.
