%X Using mobile sink to gather data is one of the comprehensive trends in wireless sensor networks. This paper proposes an energy-efficient and delay-sensitive data gathering protocol (EEDS)for wireless sensor networks. In EEDS, The mobile sink traverses in the entire network to upload the sensed data from agent nodes. In order to reduce the length of path which mobile sink traverses the network, the solution of TSP-like is proposed, which ensures mobile sink always choose the shortest path to walk through the network. Simulation results have demonstrated that the proposed data collection strategy has a significant advantage in extending the network life time and reducing data transmission delays.
