Energy-Efficient Approach for Node Selection in Routing Protocols of Wireless Sensor Networks

The fundamental constraint in wireless sensor network operation is that sensor nodes placed in the network possess limited energy. Researchers have devised energy-efficient techniques to deal with the constraints. Authors suggest a new approach to energy efficient node selection that extends the network's overall lifespan. Each node's trust level, connectivity degree, and distance from the sink are individually analyzed and weighted before being aggregated linearly. It provides node's effective potential function, leading to an energy-efficient node. Required rounds for selecting the most energy-efficient node are also equated. New approach comparison with traditional method using energy distance for routing protocols such as Shortest Hop Routing (SHORT), Power Efficient Gathering in Sensor Information Systems (PEGASIS), Optimized Reduced Energy Consumption (OREC), and Load Balance and Energy Efficient Routing Algorithm (LBEERA) is done through simulation. Using new approach which carries the energy efficient node selection, noteworthy extended 8% improvement in network lifetime is obtained.
