Relay Node Placement in Wireless Sensor Networks: A Survey

Recently, wireless sensor networks (WSNs) have been immensely used in many real-life outlines, and have become very important. These sensors sense some physical phenomenon and then gathered information is processed. Sensor nodes may be affected from a huge distortion in severe surroundings, that causes the network to get split into multiple disjoint segments. Now to join these segments (in WSNs) is very crucial. However, if the connectivity of the network has been more dense, it will get more rough. In this paper a Relay node placement scheme in WSNs that unites disjoint segments with less number of Relay nodes is considered. Number of techniques are used for implementing it.
