摘要 无线传感器网络是以数据为中心的信息处理系统。本文根据目标跟踪对信息处理的需求,提出了协同信号与信息处理CSIP的概念,设计了基于MICA2节点和PDA的CSIP策略的实验,并采用基于(m,k)-firm的丢包策略。实验显示基于(m,k)-firm的策略比EDF更能减少信息的丢失率,并能够降低信号的失真。 Wireless sensor network is data-centric signal processing system. In this paper, the concept of Collaborative Signal and Information Processing (CSIP) is proposed for the requirements of signal processing in target tracking. The experiments for evaluating CSIP based on MICA2 and PDA platform were designed, and (m,k)-firm based scheduling scheme was adopted. Experimental results reveal that the (m,k)-firm based scheme is more effective in decreasing the information loss-rate and reducing the signal distortion than EDF.
