Deployment of Multiple Sink in the different Monitoring Area based on Optimization Technique
Wireless Sensor Networks are widely used in different applications like environmental monitoring, health monitoring, wildlife monitoring, etc. The monitored area may be of any shape such as circular, rectangular, and square. Finding an ideal node deployment technique in wireless sensor systems (WSNs) that would diminish cost, be powerful to node failure, shorten calculation, and communication overhead, and guarantee full coverage alongside network connectivity is a troublesome issue. Indeed, sensing coverage and system connectivity are two of the most basic issues in WSNs as they can straightforwardly affect the system lifetime and activity. In traditional WSNs, a single sink is deployed which results in more traffic load on that sink cause higher energy consumption. Thus, it is necessary to deploy multiple sinks. The efficient deployment of sensors and multiple sinks is a challenging task as the performance of the network is depending on it. In this paper, sensors and multiple sinks are deployed using SSDOA (Sensor Sink Deployment Optimization Algorithm) in a different monitoring area. Performance parameters like coverage, network lifetime, energy consumption are analyzed. Compared to existing methods our method performs better in any type of monitoring area. Reported numerical results show that our method outperforms PSO, GA and Random deployment in the square monitoring area with 9% better network lifetime, 4% full coverage and 7.3% lesser energy consumption respectively. Furthermore, our proposed approach also performs better in the circular and rectangular monitoring area.
