Wireless sensor networks are the grouping of tiny sensor nodes that gathers the information by sensing activeness from the surroundings similar lands, forests, hills and sea. Power saving is a critical issue in wireless sensor networks since sensor nodes are battery-powered. To achieve optimized network performance at collecting a small portion of sensed data in network is in current researches. There are many protocols available for the successful communication. Sink trail and sink trail-s are the two energy efficient proactive data reporting protocols for mobile sink based on data collection with low complexity and reduced control overhead.
