An Energy-Aware Routing Protocol for Query-Based Applications in Wireless Sensor Networks

Abstract EN

Wireless sensor network (WSN) typically has energy consumption restriction.

Designing energy-aware routing protocol can significantly reduce energyconsumption in WSNs.

Energy-aware routing protocols can be classified into twocategories, energy savers and energy balancers.

Energy saving protocols are used tominimize the overall energy consumed by a WSN, while energy balancing protocolsattempt to efficiently distribute the consumption of energy throughout the network.

Ingeneral terms, energy saving protocols are not necessarily good at balancing energyconsumption and energy balancing protocols are not always good at reducing energyconsumption.

In this paper, we propose an energy-aware routing protocol (ERP) forquery-based applications in WSNs, which offers a good trade-off between traditionalenergy balancing and energy saving objectives and supports a soft real time packetdelivery.

This is achieved by means of fuzzy sets and learning automata techniquesalong with zonal broadcasting to decrease total energy consumption.
