Abstract
The use of wireless sensor networks (WSNs) has become an inevitably necessary for a smart world, such as smart cities and environmental fields. WSN consists of hundreds or even thousands of sensor nodes that have the ability to sense physical conditions from the target field, and also consists of a device that acts as a link between the sensor nodes and the base station (BS) called cluster head (CH). In the recent years, researchers have become interested in optimizing the energy efficiency of the WSNs due to the limited and non-replenish energy sources of their sensor nodes. In this paper, we present a review of main methodologies used in the literature to improve the energy efficiency of WSNs and extend the lifetime of the network. In addition, we present the general energy model that is used in these networks. Moreover, we discuss new research directions for efficient network-energy utilization that need to be considered for implementing power-constrained WSNs.
