Performance Analysis of Various Energy Efficient Schemes for Wireless Sensor Networks (wsn)

Fast growth of wireless services in recent years is an indication that considerable value is placed on wireless networks. Wireless devices have most utility when they can be used anywhere at any time. One of the greatest challenges is limited energy supplies. Therefore, energy management is one of the most challenging problems in wireless networks. In recent years, Wireless Sensor Networks have gained growing attention from both the research community and actual users. As sensor nodes are generally battery-energized devices, so the network lifetime can be widespread to sensible times. Therefore, the crucial issue is to prolong the network lifetime. In this paper, various Energy Efficient Schemes for Wireless Sensor Networks (WSN) has been compared. Many techniques like Aggregation, Scheduling, Polling, Clustering, Efficient node deployment scheme, Voting and efficient searching methods are used to increase the network life time. In the deployment of nodes using Multi Robot deployment of Nodes method, the result shows that the percentage of reduction in energy consumption is 4%. The Aggregation routing method, analysis shows that the percentage of reduction in energy consumption was 21%. The percentage of reduction in energy consumption is 26% in the effective search technique called Increasing ray search method. In the Voting Scheme, the result gives that the percentage of improvement in energy savings is 34%. The improvement in energy saving is 51% in the Polling method. As per the analysis, polling scheme was very much effective in terms of reducing the energy consumption in Wireless Sensor Networks.
