Intelligent Sensor Network
Wireless sensor networks have emerged in recent years as a new information gathering paradigm using collaborative effort with the support of a large number of sensing nodes.
Our objective is to develop location sensing algorithms and approaches for a wireless sensor network that enables the network coordinators to locate individual sensor nodes and effectively acquire maximum information of the environments with minimum resources. In this project, we consider an intelligent sensor network that consists of a number of sensors spread across a geographical area. It is assumed that each sensor has wireless communication capability and sufficient intelligence for signal processing and networking of the data.
Our focus is on the problem of sensors management in a dynamic environment.
Specifically, we would investigate a sensor network system that comprises
rapidly deployable sensor nodes for security surveillance applications suitable
for use in quick and short term setup. For this investigation, we will develop
a demonstration prototype that comprises hundreds of sensor nodes. The sensor
nodes would be battery powered and equipped with wireless short range communication
capabilities and suitable sensors. In this application, it is important
that the system is able to provide full sensing coverage while conserving
energy consumption to extend system life by leveraging the redundant deployment
of sensor nodes. Communication protocol will be developed based on 802.15.4.
Intelligent management of energy resources would be developed through the
MAC to ensure the sensor nodes could serve the intended period. Innovative
optimal routing method and data fusion algorithm will be also be developed.
