Aqua Sim for NS2 - Underwater Sensor Networks

Image
Sensor nodes deployed inside water are known to be underwater sensor networks. These network is helpful in fish cultivation, habitat monitoring, predicting ptusami, etc.

Updated 9th April 2016 : the link to download the Aquasim is updated, the regular link is not working

This network uses different MAC protocol, routing protocol, etc. Real test bed are costlier and one cannot afford it. Simulators are the ultimate solution to know about these networks. Aquasim is one such tool that is integrated in ns2 for handling underwater sensor networks. This simulator supports new mac layer, new protocols that are helpful in routing inside water. There are examples also to simulate these networks.

Here is the installation steps of Aquasim.  Some points to be taken care of
ns-allinone-2.30 is used in creating the underwater sensor networks nam misbehaves (or does not work) in recent Ubuntu and Mint distributions.  Need to have the X11, automake and build essential tools to install Aquasim. Install…
