The Application of Reprogramming Technology in a Wireless Sensor Network

Abstract

Wireless sensor networks can collect physical world information in a large, long-term and real-time manner in a complex environment. Wireless sensor networks have been successfully applied in many fields. With the development of wireless sensor network, wireless sensor network applications need to update the executable code on the sensor due to the change of application requirements. The researchers call this a wireless sensor network application reprogramming, or simply reprogramming. The efficiency of reprogramming is closely related to the size of the updated code that needs to be distributed and the amount of traffic to be distributed. This paper firstly expands the classical logic language based on the characteristics of wireless sensor network, and implements the language by compiling/interpretation, which can generate the smaller update code. Secondly, the paper also makes full use of the location information of the sensor and the data distribution protocol of low message complexity of telecommunication and channel resources. The research results of this paper can effectively reduce the communication volume of the distribution process.
