Understanding PEGASIS in Wireless Sensor Network

PEGASIS, or Power-Efficient GAthering in Sensor Information System, is an important protocol in Wireless Sensor Networks (WSN). It helps solve one of the key challenges faced by WSNs—energy efficiency. In WSNs, sensor nodes are often deployed in remote areas and have limited battery power. Extending the network's lifespan requires minimizing the energy spent on data transmission, and PEGASIS does just that by organizing sensor nodes into chains. In this video, we’ll dive deep into how PEGASIS works, its importance, how it differs from other protocols like LEACH, its applications, limitations, and future enhancements.
