Along with tutoring service on NS-2, we offer support for NS-2 based projects, assignments, lab cycles etc. As a step towards our guidance, we also have provided few basic concepts of NS2 below, for students to get some knowledge about NS It is also an open source simulator widely used for Educational and research purpose.

It is also used to simulate both wired and wireless Networks [Mobile Ad hoc Networks, Wireless sensor Networks, Wireless body area network etc]. Simulation in NS2 is based on the following constraints i. This is the base of our entire work i. We also have provided a compact knowledge tutorial in Ns-2 for beginners to learn few basics of NS This will give them the base foundation to undertake their final year projects or research work.

As we also have develop numerous projects in NS-2, we also know about the major concepts in NS-2, which scholars must know. This is the reason; we also have provide this article for you.
