Investigation of Target Based Routing Approaches in Wireless Sensor Networks

Nowadays, wireless networks can be used in interaction with many novel applications such as, traffic monitoring, battlefield survey, monitoring based on sensors and distribution networks. Wireless sensor networks are one of the important applications of cyber-physical systems in which information is collected from the surrounding environment by using a large number of sensor nodes in a wide environment. A wireless network can be a community of sensor networks with computing and information devices. These systems can intelligently monitor the state of the surrounding environment and react with an intelligent response to the events of the surrounding environment. Due to the technological limitations and environmental influences, the sensor data collected by these systems are inherently noisy and may have may issues and false alarms, and it is highly desirable to sift meaningful information from a large set of noisy data. Target tracking in these systems is a critical problem that has occupied many researches and in recent years, with the realization of the possibility of building wireless sensor networks, the use of these networks in different environments for tracking moving targets has also been proposed, and one of the most important issues in this Networks are considered. In this research, we investigate the approaches of tracking targets on wireless sensor network. We present the issues and problems of tracking, then we continue to review the common tracking methods in these networks and related qualitative parameters.
