Despite the increasing use of the wireless sensor network in many applications, especially
critical ones, exploiting the full potential of this network is very difficult due to many
challenges. In general, sensor data contains a huge number of redundant data that change
the overall network performance. In recent years, a data aggregation scheme played an
important role in wireless networks to overcome many of its issues. This paper is divided into
third parts, the first part focused on a description of the wireless sensor networks and their …
