Abstract

Sensor nodes are typically less mobile, much limited in capabilities, and more densely deployed than the traditional wired networks as well as mobile ad-hoc networks. General Wireless Sensor Networks (WSNs) are designed with electro-mechanical sensors through wireless data communication. Nowadays the WSN has become ubiquitous. WSN is used in combination with Internet of Things and in many Big Data applications, it is used in the lower layer for data collection. It is deployed in combination with several high end networks. All the higher layer networks and application layer services depend on the low level WSN in the deployment site. So to achieve energy efficiency in the overall network some simplification strategies have to be carried out not only in the Medium Access Control (MAC) layer but also in the network and transport layers. An energy efficient algorithm for scheduling and clustering is proposed and described in detail. The proposed methodology clusters the nodes using a traditional yet simplified approach of hierarchically sorting the sensor nodes. Few important works on cross layer protocols for WSNs are reviewed and an attempt to modify their pattern has also been presented in this paper with results. Comparison with few prominent protocols in this domain has also been made. As a result of the comparison one would get a basic idea of using which type of scheduling algorithm for which type of monitoring applications.

Highlights

A Sensor node in Wireless Sensor Networks (WSNs) is small, its power supply unit should be very small and it should support all its operations without degrading the performance
The results show that the BSMA outperforms other centralized Time Division Multiple Access (TDMA) protocols, and has more energy efficiency when compared with that of the other distributed protocols
Some limitations are 1) the developed Load and Energy Consumption based Scheduling Algorithm (LECSA) is suitable only for WSN with multiple nodes used in Environmental Monitoring applications

Summary

1- Introduction

A Sensor node in WSN is small, its power supply unit should be very small and it should support all its operations without degrading the performance. In a dense WSN, there will be very high data traffic resulting in high energy wastage if there is one to one communication between the sensing node and gateway node with increased collisions. A Load and Energy Consumption based Scheduling Algorithm (LECSA) has been proposed and it works efficiently in the MAC layer.

Using this technology, all our day today activities can be made automatically manageable from remote places. The research subject of energy efficient protocol for WSN explained in this paper definitely will be a promising domain for most of the future research works
