The objective of system is to use sink mobility to prolong the network lifetime in wireless sensor networks where the information delay caused by moving the sink should be bounded. In this paper, a unified framework for analyzing the joint sink mobility, routing, delay, and so on is built. The induced sub problems are studied and then present efficient solutions for them. Then, we generalize these solutions and propose a novel approach-HSDT algorithm for the origin problem. Proposed system

Furthermore, a study on the effects of different trajectories of the sink and to provide important insights for designing mobility schemes in real-world mobile WSNs is performed.
