Wireless Sensor Networks (WSNs) have attracted growing interest from both realcustomers and the scientific community in the recent years due to their powerfulcapabilities and varied applications. Each wireless sensor node relays data to thebase station (BS) directly in the direct communication protocol. However, there aresome applications that require some of the nodes to be placed at vast distances fromthe BS, which leads to rapid reduction in the total energy of all nodes. Since energyconsumption in sensor networks is critical, many new protocols have beendeveloped to reduce losses. The Low-energy adaptive clustering hierarchy(LEACH) is one of the most popular protocols that increase network lifetime byreducing losses. In this report, I survey and compare some algorithms and propose a new enhancedalgorithm for the LEACH protocol, thus saving energy and prolonging the networklifespan. MATLAB is used for simulation.
