An Efficient Data Redundancy Reduction Technique with Conjugative Sleep Scheduling for Sensed Data Aggregators in Sensor Networks
Authors: ,
Abstract: An Efficient Data Redundancy Reduction (EDRR) scheme extending the life time of sensor nodes on wireless sensor networks has been proposed in this paper. Normally, in Wireless Sensor Networks (WSN), more energy is needed for transmitting data. In our earlier work, conjugative sleep scheduling scheme with Connected Dominating Set (CDS) for parent selection has been proposed. Whenever a sensor node fails or a new node is added to the network, the conjugative scheduling scheme evaluates the route maintenance algorithm. Remaining power levels of nodes have been examined in order to increase the network lifetime. This proposed work integrates conjugative sleep scheduler scheme with data redundancy reduction scheme. This energy efficient redundancy reduction scheme basically utilizes Differential Pulse Code Modulation (DPCM) technique. Rake receiver model data aggregation is adopted for aggregating the data from various sensor nodes. Finally, the performance of EDRR scheme is compared with existing energy efficient protocols. Based on extensive numerical experiments, the proposed scheme is evaluated in terms of Throughput, Energy Drain Rate, Power Consumption and Network life time.
