Query: Nviz - A General Purpse Visualization tool for Wireless Sensor Networks   In a Wireless Sensor Network (WSN), data manipulation and representation is a
crucial part and can take a lot of time to be developed from scratch. Although
various visualization tools have been created for certain projects so far,
these tools can only be used in certain scenarios, due to their hard-coded
packet formats and network's properties. To speed up the development process, a
visualization tool which can adapt to any kind of WSN is essentially necessary.
For this purpose, a general-purpose visualization tool - NViz, which can
represent and visualize data for any kind of WSN, is proposed. NViz allows
users to set their network's properties and packet formats through XML files.
Based on properties defined, users can choose the meaning of them and let NViz
represents the data respectively. Furthermore, a better Replay mechanism, which
lets researchers and developers debug their WSN easily, is also integrated in
this tool. NViz is designed based on a layered architecture which allows for
clear and well-defined interrelationships and interfaces between each
component.
