Energy Optimization in Redundant WSNs under Deterministic and Probabilistic Sensing Models

Abstract

Almost all WSNs are deployed with some redundancy degree which is used only for robustness objectives. If not handled in an intelligent way, redundancy results in energy wasting because of redundant transmission and reception operations. In view of this energy wasting, a redundancy detection method under sensing models is proposed. We propose to take benefit from measurement redundancy to optimize the energy consumption and improve the end-to-end delay. We propose OER (Optimization of Energy based on Redundancy) protocol, to improve energy consumption in WSNs.

Exploiting redundancy for energy-efficiency in Wireless Sensor Networks

“…To exploit spatial redundancy in WSNs, we implement OER [7] an energy optimization protocol in redundant WSNs under deterministic and probabilistic sensing models to take benefit from measurement redundancy to optimize the energy consumption. We also improve it with FTMOer, a fault-tolerance mechanism.…”

“…In this paper, we are interested in redundancy in wireless sensor networks. Consequently, we implemented OER [7] in NS2 to show the benefits of exploiting the redundancy in terms of energy consumption. Besides, we extended it by a fault tolerance mechanism (FTMOer).…”
