  1. Critical Sensing Range for Mobile Heterogeneous Camera Sensor Networks Yitao Hu, Xinbing Wang, XiaoyingGan Department of Electronic Engineering Shanghai Jiao Tong University, China

  2. Outline Basic Idea Main Contribution System Model Numerical Analysis

  3. 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

  4. Main Contribution Derived the Critical Condition Considered the characteristic of Heterogeneity Considered the characteristic of Mobility
