A Multi-resolution Task Distribution Method in Mobile Sensing System

With the popularity of mobile phones, mobile sensing system has become an important research area in wireless sensor network. In this paper, a multi-resolution task distribution method for mobile sensing system is presented. First, a task map of sensing area is defined according to its physical map. Then a set of of information parameters are designed, and the task map is encoded. Thus the mobile nodes are capable of downloading the task map using parametric encoding map. In our proposed method, mobile nodes can stop receiving task map at any time, and a task map with suitable resolution is obtained. Through experiment about error rate of parametric encoding, multi-resolution receiving method and encoded information size, we can conclude that parametric encoding and multi-resolution receiving are suitable for mobile sensing system.
