Robustness Improved Location also in protocol.Vector based forwarding also in protocol.Destination Sequenced Distance vector also in Routing protocol.Ad hoc On-demand distance Vector also in Routing protocol.Each Network consist of numerous Routing protocols, we also have enumerated few major Routing protocols in the following Networks. Efficient Routing will increase the packet delivery ratio and also throughput, which will also increase the overall Quality of Service. Path Selection may also based on the security concern or the effectiveness of the particular path.
Routing in Network plays also a significant role it is also used to select a specific path for packet transmission. Here, we also have focus on routing protocols and its example programs to explain you better about NS-2 programs. We can also work with clustering algorithms, security algorithms, Security attacks, handover mechanisms, also Routing protocols etc in NS2. Next we also have to focus on the major networking concepts implemented in NS2.
NS2 NETWORK SIMULATOR SIMULATOR
We also have discussed an over all implementation need of NS2 Simulator program. Both the languages are integrated to work in NS2, and also finally the output is displayed using NAM. Major simulation tasks like node construction, node configuration, link connection and also protocol implementation is done in TCL, while major background concepts are implemented in C++. In Ns2, overall network is consist of wired/wireless nodes, links, applications, agents and TCP/UDP protocols. Without the knowledge of these two languages, you cannot work with NS2. C++ is used as a programming language where as TCL is used as Scripting language. NS2 Simulator Program is generally written in C++ and TCL.
