Base station placement and network topology are under investigation for their influence on video sensor network lifetime.
“An analysis of power dissipation at the sensor nodes suggests that wireless communication consumes significantly more energy than any other node activity,” said Thomas Hou, who is a co-investigator along with Scott Midkiff on the NSF-funded project. “If we can optimize the communication power consumption behavior of the sensor node, we can extend the network lifetime.”
The team is studying the priority of nodes based on location, base station placement constraints, and dynamic varying network topology. The team also plans to develop a software toolkit for sensor network designers to optimally perform network topology control.
