Wireless sensors network are becoming more popular in environmental monitoring, healthcare applications and etc. Since they are either worn or implanted into human body, these sensors must be very small in size and light in weight. Now-a-days, many studies exploit cluster head techniques to collect large scale database sensor data for environmental observations or weather forecasting. Agent (cluster head) travels in sensing areas and collect data directly from each sensor. By using DPV (Delivering Predicted Value) method, data can be collected and drop unused data thus the authors can say that they reduce communication traffic.
