Abstract:

The wireless sensor network technology spawns numerous unforeseen 
applications. The diversity of these emerging applications interprets the 
great success of this technology. However, the energy constrained nature 
of wireless sensor networks requires the utilization of energy saving 
techniques to maximize the network lifetime. This article provides an 
overview of energy saving techniques to achieve a sustainable sensor 
network design. By specifying where and how energy is consumed, we 
classify existing energy saving techniques into two categories: the 
node-level energy saving and the network-level energy saving. For each 
category, a surge of existing protocols and techniques are presented with 
focuses on energy efficient MAC-layer protocol design, power control, 
energy efficient routing and information volume reduction, the four rising 
aspects that attract significant research attention in recent years. 
MAC-layer protocols and power control, respectively, save the node-level 
energy from the temporal domain and spatial domain. Both aim to prolong 
the lifetime of each individual sensor node. Moreover, energy efficient 
routing and information volume reduction together belong to the category 
of the network-level energy saving, which are tailored for increasing the 
network lifetime to achieve a sustainable system design. In this survey, 
we emphasize the basic principles of energy savings to understand the 
state-of-the-art. Meanwhile, we explore future research directions in the 
new and largely open areas of the sustainable sensor network design.
