Hi, I'm new to ns2 and I really need help.
What I want to achieve using the ns2 is to add tags to each packets with different priorities (high or low). When the nodes forwards the packets to the intermediate node, the intermediate node will have a kinda filter algorithm which will filter the packets and forward the packets with high priority to the sink. In this case, the data in the high priority packet will not be lost. Also plotting the graph showing the packets dropped and throughput achieved. The nodes would be arranged like n0,n1,n2 connected to n3(intermediated node) and n3 connected to n4(sink). Main aim is to achieve fairness and conserve energy as well, Thanks
