Remember! Atarraya is a free software, but you need to reference it when used in you public work.
In order to be able to notify you with the latest information about Atarraya,
we encourage you to email Dr. Miguel A.

with the following information:
If you are a student, please include the your advisor's information.
Atarraya's code is a Netbean 6.9.1
project folder, contained in a .rar or .zip file
of less than 2MB. You will need Java 6. For linux users, the GUI style
has been formatted based on Windows' design, but it can be changed on the
Main class of the project; however,
it will require some effort to format the GUI under the default scheme.
The following is a list of the latest versions of Atarraya and the list of bugs
fixed and features added:
Atarraya 1.3 beta - Public version NEW!!
This version includes several new features:
A renewed internal structure of the application, following a Facade-Observer design pattern which
the GUI from the functional sections of the code. This should allow the development of non graphical GUI for Atarraya.
The inclusion of the idea of communication model, which now allows the development of realistic radio propagation models that
will allow the development of more robust protocols. Atarraya now includes the radio and energy models of the XBow Mica2 and
the Libelium WaspMote motes. You are more than welcome to develop your own!
Some tweaks of the GUI in order to improve the quality of the graphics of the network topology, and the file type to save it on.
This version includes two new topology construction protocols: A3Cov, based on A3 but that takes into account coverage as well
as connectivity, and KNEIGH-Tree, a modified version of the KNEIGH in which a few simple changes now guarantee connectivity in the network.
We solved a very strange bug that made the node data structure to return null values under unknown conditions
The energy model was changed from the NodeNetworkConfiguration
class to the Node class. It carries some changes to the protocols
because now the invocations of the UseEnergy method do not need the
definition of the active VNI or tree
The energy model now is part of the creation word of the node and
will be stored and read from the topology file. If that parameter is not
in the deployment file, Atarraya will use the default value of 0
Grid Lambda: based on a grid with cell size of Rsense*Rsense grid, lambda nodes are deployed randomly in each cell
Grid Poisson: based on a grid with cell size of Rsense*Rsense
grid, a Poisson(lambda)-distributed random number of nodes are deployed
randomly in each cell
Atarraya 1.2 Beta 5 and 5.1
Creation of the brute-force algorithm for solving the MCDS
problem. It can work with multiple files and generate a summarized
results report file
The simulator has a new option to save the results (active nodes) of the Topology Construction experiment
Atarraya 1.2 Beta 4
Elimination of the semaphore in the GetNode() method to save time
Reduction in the refresh rate of the clock and the current events; those two slowed down greatly the simulation
Other changes to reduce execution time
Atarraya 1.2 Beta 3 - Public version
New support for different energy model. Apart from the simple
model, a new "in development" energy model for the nodes is introduced,
based on the specifications of the
Mica2 motes. The values are still in revision, so any contributions on
that matter will be more that welcome.
Implementation of a new topology construction protocol, based on
the KNEIGH algorithm. This protocol modifies the network topology by
reducing the transmission range of
the nodes. This is the first algorithm of its kind implemented in
Atarraya, so it can be used to develop new algorithms. However, this
algorithm is not the pure KNEIGH, in the
sense that the execution of the algorithm follows the creation of a
tree, similar to the JustTree algorithm, already implemented in
A new option to reset a loaded topology, without having to loaded again
New GUI that simplifies the execution of batch simulations
Improved the statistics provided in the lifetime analysis
The mobility model can be applied now just to a subset of the
nodes. This can be done by checking the "move?" checkbox during the
addition of a new creation word.
Atarraya 1.1 - Public Version
This version includes the mobility module for the nodes in the
topology. The mobility is modeled as another EventHandler. A simple
is included: a node will move a random distance no greater that a
parameter d, and the position change will be executed randomly
discretely in time,
with a time delay no greater than a variable t. The discrete time can
be assumed as the delay between the position is being updated
A new option to save a snapshot of the topology in a jpeg file.

Politehnika”, Lviv, Ukraine.
