Wireless Sensor Network (WSN) is a group of nodes has a function to collect information by using routing technique and one of the schemes can be used is clustering. Broadly, in a large area, sensing done by nodes needs massive energy. It can be seen via rounds executed. The smaller the round value, the profuse the energy usage. A problem appears when the round mechanism almost reaches its saturation but the sensing is still needed to be run. Then, how to make the round value as large as possible becomes a solution to confront that problem. In this study, Distributed Energy Efficient Clustering (DEEC) is going to be analyzed. The protocol is going to be compared with Low Energy Adaptive Clustering Hierarchy (LEACH) as a basis protocol. The simulation for comparison is going to be executed to know network lifetime based on the parameters used which are an area size and the number of nodes. All parameters are going to be set in distinctive values and the nodes are spread randomly. Based on scenarios simulated, DEEC produces better performance than LEACH. It has more around 50% network lifetime than LEACH. It can be marked that the number of rounds of DEEC created is bigger than the number of LEACH rounds. The total DEEC packets delivered to cluster-head from sender node are around 20% larger than LEACH packets delivered. In addition, for total packets sent to base station from cluster-head, DEEC packets sent has around 75% greater than LEACH packets transmitted. |
