This paper briefly introduces the problem of information data processing in wireless sensor networks. Based on data sampling characteristic of ADC of wireless sensor networks Motes hardware platform, we propose a simple and effective data compression algorithm SEC, whose effective is validated by the experiments research on audio signals sample and transmission
The problems related to weakly hard real-time system have been attracted by scholars in this field. This paper summarized current static scheduling algorithms by analyzing how to select a concrete mu-pattern, proposed two main issues in static scheduling and presented a simulation example of static scheduling on a network based multimedia application whose tasks achieved lower delay
Many routing protocols have been proposed for wireless sensor networks in recent years. For some special applications, not only energy aware but link reliable is needed. Historical link status should be captured while making routing decisions. In this paper, we design a reliable link quality estimation based routing protocol (LQER), which integrates the approach of minimum hop field and (m, k). The...
