Abstract
Ongoing advancements in electro-mechanical, power electronics and wireless communications have made possible the use of wireless sensor networks in remote applications such as environmental conditions, forest fire protection and target monitoring in military applications. These unattended applications require a huge number of sensor nodes working efficiently together for a common goal. Since sensor nodes have limited energy resources, it is of vital importance to use them in an efficient manner to improve a network’s lifetime. One of the most important methods to achieve this is by making clusters. Nodes may not have the same energy, which makes it even more important for these clusters to work efficiently together in order to save power. Wireless sensor networks are of homogeneous and heterogeneous type. This paper presents a survey on energy efficient clustering mechanisms in heterogeneous wireless sensor networks. Nodes in homogeneous wireless sensor networks have similar resources, however heterogeneous networks have nodes with different energy levels that can be used effectively to enhance a network’s lifetime.
