Abstract
<p>Energy efficiency has been considered as the most important issue in wireless sensor networks. As in many applications, wireless sensors are scattered in a wide harsh area, where the battery replacement or charging will be quite difficult and it is the most important challenge. Therefore, the design of energy saving mechanism becomes mandatory in most recent research. In this paper, a new energy efficient clustered routing protocol is proposed: the proposed protocol is based on analyzing the data collected from the sensors in a base-station. Based on this analysis the cluster head will be selected as the one with the most useful data. Then, a variable time slot is specified to each sensor to minimize the transmission of repetitive and un-useful data. The proposed protocol Data-Based Energy Efficient Clustered Routing Protocol for Wireless Sensors Networks (DCRP) was compared with the famous energy efficient LEACH protocol and also with one of the recent energy efficient routing protocols named Position Responsive Routing Protocol (PRRP). DCRP has been used in monitoring the floods in Tabuk area –Saudi Arabia. It shows comparatively better results.</p>

7.1 Data-based energy efficient Clustered Routing Protocol (DCRP) versus Leach Protocols The performance of the DCRP is compared with LEACH and Position Responsive Routing Protocol (PRRP) protocols
It is clearly observed that the system using DCRP protocol has more live time than that for LEACH protocol
Summary
The recent development in sensors technology and communications media has steered to a wide use of sensors networks in many applications. Those applications include environmental monitoring, oil exploration, disaster alert system, flood monitoring and alerting system, and etc. Limited energy is the hot issue, which was discussed widely in the literature, and many different communications protocols in different layers were proposed and developed. The most severe one is called Wadi Dom which runs from the west towards Tabuk for more than 150 km. It is selected as the case study in this work.
