چکیده

In this paper, we analyze the operating principle of LEACH protocol and present an improved algorithm LRDA (LEACH Region Divided Algorithm) proposed for large-scale wireless sensor networks. The main idea is dividing network into different sizes of areas according to the theorems of optimal number of hops and the minimum energy consumption in ideal conditions. The cluster heads use multi-hop communication to send their data to the base station. The clusters closer to the base station have smaller sizes than those farther away, thus the cluster heads closer to the base station can preserve some energy for data forwarding. The protocol broke the network scale limit and balanced the energy load of the cluster heads. Simulation shows that it prolongs the lifetime of the network and increases the throughput of the network.
