A Wireless Sensor Network (WSN) can be described as a collection of untethered sensor nodes. An important application of WSN is in the field of real-time communication. Real-time communication is a critical service which requires a qualitative routing protocol for energy-efficient network communication. The judicious use of energy of the network nodes is essential and important for sustainability and longevity of a WSN. This paper proposes an algorithm namely 'Priority-Energy Based Data Forwarding Algorithm (PEDF)' which empowers the node to choose the most suitable packet forwarding path, based on the priority of the packet and the current energy status of the forwarding node.
