A new Sink Placement Strategy for WSNs

摘要

In this paper, we have urbanized a fresh sink placement policy in Wireless Sensor Networks (WSNs). We studied the problems in previous sink placement strategies such as RSP, CNP, GOSP, SOSP, CLHM, ISP, and GSP. These previous sink placement strategies are not concerned about dynamicity of the network under consideration. The information about sensor nodes positions is not known beforehand in concerned WSN environment. On the reverse, GSP policy is designed particularly for unidentified feeler nodes site and is proposed as a standard sink placement policy in WSNs. So, GSP has been chosen to compare our strategy that reduces both energy consumption as well as routing overheads. We are proposing the new and improved strategies which work on concentric ring routing principle with and without density. In with density, a new random protocol used, in which the location of sinks are placed according to the density of the nodes and in the new uniform protocol they are fixed.
