Optimal Placement of Sink Nodes in Wireless Sensor Networks to Increase Network Performance

What is it about?

In traditional wireless sensor networks (WSNs), a single sink or base station is used to gather data from the whole network which suffers some serious performance issues, like latency, congestion, network failure, etc. Deploying multiple sinks in WSNs can improve network performance, but it increases sink deployment costs. In this paper, we propose distributed algorithms to find out the minimum number of sinks to be deployed and their optimal positions in the deployment region, while ensuring a certain latency and fault tolerance level.
