Wireless Sensor Network Application Platform System Network Layer Design And Implementation

Combination of wireless sensor network of micro-electromechanical systems, sensors and networks of three technologies, as a new information acquisition and processing technology, military, environmental, medical and commercial fields have a wide range of applications, and has a huge market Prospects. Wireless sensor networks to people's lives change in a subversive, in 2003 the United States, " Business Week"will be a new wireless sensor network technology as one of the four.This article describes the basis for wireless sensor networks int the logistics network in the application of a set of design software as a service model based on the softwaresystem. The system provides for the application of information technology information platform for wireless sensor network applications platform, the network listener, tracking, monitoring, network management and diagnostics.In this thesis, the following work:a brief analysis of the wireless sensor network application platform design and implementation of research background and significance, including the concept of wireless sensor networks, Characteristics, applications and wireless sensor network application platform system of the structure, main Theory; introduced wireless sensor network applications platform system of therelated technology, for follow-up of wireless sensor network applications platform pave the way for the design and implementation; details of the wireless sensor network applications platform system solution, the network layer, application layer Structure, logic layer,in particular, describes the design of the network layer;detailed description of my network applications platform for wireless sensor network layer design and implementation of the code of the three modules, namely, to start the service module, stop the service module, network log module And explains the code used in the design of two key technologies: Asynchronous Socket communication and multi-threading. One paper in the wireless sensor network application platform is a set of intermediateapplications, and sensing application int the upper two-way inter-network transmissionof data efficiently,to achieve a wireless sensor network with a variety of techniquesbased on wireless sensor network Two-way communication between the applicationservices.
