Distributed Coordinated Mobile Sensor Control Target Tracking in Multiple Wireless Sensor Networks

Wireless Sensor Networks (WSNs) is highly distributed network of small, lightweight wireless nodes. It monitors the environment or system by measuring physical parameters such as temperature, pressure, humidity. A wireless sensor network is a collection of nodes organized into a cooperative network. The existing presented Mobile sensor controller is used to measure the mobile target signals time of arrival (TOA). Its related to tracking signal-emitting purpose of mobile targets which is used to navigated mobile sensors based on signal reception. Mobile targets position is unknown so that they acquire from TOA. Both the mobile target and mobile sensor are used to estimate their locations before they directing mobile sensors movement to follow their target. TOA measurements are easy to acquire the mobile target. However, in Distributed Coordinated Mobile Sensor Control Target Tracking (DCM-SCT) scheme provides the formulation work which is done through the control of multiple cooperating autonomous sensor platforms. The proposed work provides an intelligent mobile sensor platform with high level of state information to the behavior-based mobile target tracking control system. Sensors are considered as autonomous agents and sensor motion control are based on gradient control trace with the target helps to reduce tracking error. Multiple objective functions are allows to reactive control in complex environments with multiple constraints. Simulations were conducted to measure the performance of in terms of DCM-SCT which has Location privacy level, Number of latency per packets, delivery rate, average end to end delay and control packets.
