Critical Sensing Range for Mobile Heterogeneous Camera Sensor Networks

Yitao Hu, Xinbing Wang, XiaoyingGan

Department of Electronic Engineering

Shanghai Jiao Tong University, China


Outline

Basic Idea

Main Contribution

System Model

Numerical Analysis


Basic Idea

  • Coverage:

    • to measure how well a field is monitored by sensors within the field.

  • Camera Sensor Network

    • Enrich the information of the monitored region

    • Do not possess omnidirectional sensing ability as traditional ones


Main Contribution

Derived the Critical Condition

Considered the characteristic of Heterogeneity

Considered the characteristic of Mobility
