Wireless Sensor Networks (WSNs) have become an emerging new research area in the distributed computing environment. It plays an important role in the pervasive computing to support a wide range of applications of the people daily life in future. It consists of sensor nodes with sensing and communication capabilities. The authors focus on data aggregation problems in energy constrained sensor networks. The main goal of data aggregation algorithms is to gather and aggregate data in an energy efficient manner so that network lifetime is enhanced.
