Abstract

Wireless Sensor Networks (WSNs) have gained a great deal of attention owing to their wide applications in multifarious situations and established the recent technological revolution. Two important challenges in WSNs are coverage and network lifetime. The latter, where to extend the lifetime of the network, is the most attractive issue recently. This task which required an amount of energy is done by sensor nodes, which distributed in remote locations and powered by a limited capacity of batteries has caused a limitation in both the lifetime and the performance of the WSNs. The preliminary reviews and surveys have provided a few solutions for this issue and can be classified into two main categories; energy optimization which has been addressed and discussed widely in this field of study and energy-wasting avoidance.
