A Review of Sensor Deployment Problem in Wireless Sensor Network
Wireless sensor network (WSN) have thousands of sensor nodes in a distributed environment and it is developed for controlling and verifies the natural characteristics of the sensor network. WSN is still on improving and is said to be a popular technology for checking and to work on the risky events on humans. The local sensor data that is got from the sensor node is then moved to the sink, and hence it acts as a remote base station. It is a group of sensor nodes deployed and resource constrained sensor nodes with less energy, higher computational cost, coverage and connectivity are major challenges in general deployment model. In sensor node deployment model, Target COVerage (TCOV) and Network CONnectivity (NCON) are the main issue in WSNs that have initiate significant consideration in Sensor Deployment Problem. In this review, metaheuristic algorithms are conveyed to find optimal locations for the sensor nodes as an approximate solution. Main objective is provide roadmap for researchers and development of different WSN application system. Lastly, future implementation and major open issue are highlighted.
