Wireless sensor network monitoring information must be sure that theinformation area and location， location is the basis of information-centricwireless sensor network applications， this has been particularly evident in themilitary field. Under the framework of the modern high-tech military struggle thatgave birth and development of network-centric warfare， the original informationand location of the sensor network is fundamental to operational command.A long time， wireless sensor network research mainly concentrated in themanagement and use of resources， collaboration between the layers of protocol，data integrity， network data processing and security aspects， as the premise ofthe operation of the network， the performance of the network topology ofteneasily ignored. In fact， regardless of the wireless sensor network applications，network topology structure of network performance are an inescapable problem.This article describes the key technologies of wireless sensor networkpositioning and topology networking through virtual modeling are given threetopological model. Combined with the subject of boundary conditions， eachmodel will be set high， medium and low three cloth put density， compared withNS2simulation software on the network performance under each density topologymodel， elected by the network performance can be achieved subject to therequirements of topology model， and then were selected four positioningmethods， matlab simulation positioning experiments， the unknown node ineach topology. Analysis compared the localization performance of the varioustopologies， the best topology to meet the needs of the wireless sensor networkpositioning for specific military applications， to achieve the best deployment.This article rely on the subject of a military background， away from thesecret processing only part of the research of wireless sensor network topology onthe positioning performance writing written， hoping to cause the attention of thepeople of insight on the problem of wireless sensor network topology.
