A survey and taxonomy of energy-efficient methods in wireless sensor networks

A Sensor network compromises more than one sensor that sends sensed data towards a base station (BS) in a cooperative way. There is a constraint in every sensor node, and that can be the requirement of power consuming. Every sensor node carries restricted sources of power that cannot be replaced. In the scenario of real-life as those nodes are spread into all kinds of environments, they might not be nearly put to the base station. Actually, those very nodes might be very distant from one another. Since every sensor node is battery-driven, a skillful use of power-consumption can be considered necessary for decreasing data traffic in each sensor network, hence decreasing the data required to be sent towards the (BS) thereby improving the lifetime of networks. The major aim of the data aggregation algorithms is to gather and aggregate data in an efficient energy manner, in that case, the network lifetime enhances. Here, in this work we present a comprehensive review of energy-efficient methods in wireless sensor networks. We also submit a few significant aspects of wireless sensor networks (WSNs) in relation to data aggregation as well as different data aggregation techniques. This work shows that these methods not only reduce resource consumption but also extend network life.
