Abstract This paper talk about the communication protocol named LEACH. The protocol focuses on reducing the power consumption of wireless sensor networks, which can have significant impact on the overall energy dissipation of these networks. LEACH

Power consumption is an important design criterion in the design of wireless sensor networks. Hybrid radio frequency/free space optical wireless sensor networks (RF/FSO WSN) have been proposed to reduce the energy consumption of traditional R

Wireless sensor networks with mobile sink are ex-pected to increase the flexibility for gathering information in large-scale sensing and detecting environments. Energy saving becomes one of the most important features of the sensor nodes to extend th
