Remote Monitoring System for Rainfall Measurement Based On WSN

Abstract

In the last few years, Wireless Sensor Networks have gained a lot of interest in the research field. WSNs consist of small nodes with sensing, computation, and wireless communications capabilities. Wireless Sensor Networks have inherent and unique characteristics rather than traditional networks. They have many different constraints, such as computational power, storage capacity, energy supply and etc. Many routing protocols have been proposed for WSNs out of energy aware routing protocol is very important in WSN. Most of the hierarchical algorithms proposed for WSNs concentrate mainly on maximizing the lifetime of the network by trying to minimize the energy consumption, but routing protocol which only considers energy has not efficient performance. Therefore considering other parameters beside energy efficiency is crucial for protocols efficiency. Depending on sensor network application, different parameters can be considered for its protocols. Delay and congestion management can affect routing protocol performance. In this paper, we propose Pairs Energy Efficient Routing protocol (PEER), a new routing protocol for WSNs that uses dual power management and focuses on congestion management and the delay cost. A proposed PEER is a new approach to exploit efficiently the network energy, by reducing the energy consumed for cluster forming in LEACH protocol and reducing the congestion to provide the better efficiency for the high priority data. In terms of energy consumption, network lifetime, and average delay, our protocol has performed better than LEACH (a well-known hierarchical sensor network protocol).
