A Novel Scheme for Energy-Balanced Data Aggregation in Agricultural Environment using WSN

Abstract

Wireless Sensor Networks WSNs are thickly deployed sensor nodes in an application area for example agricultural monitoring smart homes automation vehicular traffic management environment monitoring disaster finding and so on In a typical cluster based routing protocols few nodes are selected as Cluster HeadCH nodes and these nodes form clusters with other nodes in the network called cluster membersCM However energy efficiency of a sensor nodes and communication overhead are the major concerns of WSNs There are many challenges and research areas concerned in the literature one of which is power consumption in the sensor nodes Nodes in these networks have limited energy sources and generally consume more energy in long communication distances and therefore run out of battery very soon Data aggregation is an efficient mechanism in WSN to prolong the lifetime of the network Due to high node density in WSN same data is sensed by many nodes which results in redundancy This redundancy can be eliminated by using data aggregation approach by intermediate nodes while routing packets from source node to the base station BS In this paper we introduce a super CH node inside the WSN This node is in charge of all clusters belongs to WSN and also maintains energy information of all clusters All CHs send their respective information to super CH node that eliminates redundant information and forwards the aggregated information towards BS This mechanism increases the lifetime of the network by minimizing the number of communication between sensor node and BS In order to evaluate the performance of our proposed system we use various parameters like packet delay communication overhead number of live nodes and number of packet received by the BS
