We suggest event collection protocol in a specific region where sensors are deployed to detect and collect events.In the traditional multi-hop routing in wireless sensor networks reporting events to a sink node or base-station will cause imbalanced energy consumption of static sensors.To solve this problem,we use mobile sink.In this paper,we study the design of efficiency routing protocol for supporting efficient data collecting in mobile sink wireless sensor networks (mWSNs).We suggest the following two main ideas.First,we use reactive protocol to cut off unnecessary delay.Mobile sink makes a path to access to sensor node.Second,we model mobile sink movement depending on data frequency,so we can reduce moving distance efficiently.We simulate this protocol and compare it with the traditional method.Simulation results show this protocol reduces distance significantly and is suitable for mWSNs with heavy traffic.
