Self-Adapting Acquisition of Sensor Data in Mobile Environment
Chao Wang, Chunhong Zhang, Yang Ji · 2012
A mobile application meets the highly real-time requirement for data in sensor networks.However mobile applications have to handle many difficulties that do not exist in non-mobile environment.For example, the wireless network provided for mobile is slow, expensive and bandwidth-limited.So mobile application cannot acquire sensor data like a common application does, which will consume a large share of bandwidth, CPU and memory.To address this issue, we propose our design that will limit the concurrently acquisition of the sensor data with a self-adapting mechanism.It can lower the overhead of the system significantly and what's more, it hardly reduces the user experience even in the situation that the total acquisition frequency is limited.
