DESIGN OF NODE LOCALIZATION SYSTEM FOR WIRELESS SENSOR NETWORKS
Abstract: It is expounded in this article to SQL Server as a backend database, using c # as development interface design tools from a wireless sensor network node localization idea and process of simulation system, aimed at combining with practical application needs, design the experiment simulation system has practical significance, carries on the algorithm performance testing. Paper structure is composed of introduction, algorithm is introduced, system requirements analysis, system design, system implementation, and testing and conclusion of several parts, main contents include: introduction to this topic research background and significance; The wireless sensor network and the research status were summarized; Introduces the positioning of the node itself problems and significance; The architecture of wireless sensor network is expounded and its basic work mode and analyze the characteristics of its own; This wireless sensor network node from the basic concept and basic principle; Feasibility analysis of software system development and application of demand analysis; Analyze the overall system design, including function pision and database design; Elaborates the realization process of the system each function module, the analysis of the main program code; To test the implemented system function module, the analysis of existing problems and deficiencies; Finally, summarize the design.
Key Words: wireless sensor network, the node position, beacon nodes, the trilateral localization algorithm
