Attribute and Energy Aware Tree Formation in Wireless Sensor Network

Abstract

Data Aggregation is a vital technology to save energy in Wireless Sensor Network (WSN). Data aggregation has been recognized as an competent method to reduce energy consumption by dropping the number of packets sent. For data aggregation solutions, different topologies are created to aggregate the data. For e.g. line, chain, cluster and tree. In this paper, our focus is on tree based data aggregation. There are different methods of tree formation for tree based data aggregation techniques. Most of them do data aggregation efficiently in homogeneous networks but not in heterogeneous networks. Many different applications can be deployed together in WSNs and packets generated by different applications have different attributes. These packets from different applications cannot be aggregated. To make data aggregation more efficient in heterogeneous networks, Attribute and Energy aware tree formation is introduced. In this routing approach, any node will select parent of same type and having higher residual energy and there are more chances of aggregation between same type of packets so that data aggregation can be efficient even in heterogeneous networks.
