    how to store ip adress in a array in ns2?

    ReplyDelete
    Replies
    1. Ns2blogger17 April 2014 at 11:06

      we can see ip adress from trace file.NS2 nodes have hirearchichal addressing scheme which is similar to IP adderss but it is not the same. When using trace-all in NS2, a trace string is created in a trace file.it also have source and destination addresses.

      The structhdr_ip, IP packet header contains information about source and destination of a packet.NS2 utilizes data type ns_addr_t defined in file ˜ns/config.h to store node address. ns_addr_t is a struct data type, which contains two members: addr_ and port_. Both members are of type int32_t, which is simply an alias for int data type and file ˜ns/autoconf-win32.h. While addr_ specifies the node address, port_ identifies the attached port The variables src_ and dst_ of IP header are of class ns_addr_t. Hence, src_.addr_ and src_.port_ store the node address and the port of the sending agent, respectively. Similarly, the packet will be sent to a receiving agent attached to port dst_.port_ of a node with address dst_.addr_. function offset(off) and function access(p), which are essential to access IP header of a packet.

      In all the simulator the IP addresses are denoted as a nodeid. In ns2 all the nodes possess an address called SIM address with which the nodes are identified.

    Have you any code for store the ip adress ia a array?..my probs is that..in a radio coverage area ,i will compare the distance of all node to source node and find the max distance node ip adress. return the max-distance node ip to the source.

    also i more question..if a am divide the total coverage area. source node is centered of the monitoring region and also assuming that the monitoring region is divided into three fixed zone like zone1, zone2 and zone3 each of degree 120 depending upon the radio coverage area of the source node. how to write the code in ns2

    source node is centered of the monitoring region and also assuming that the monitoring region is divided into three fixed zone like zone1, zone2 and zone3 each of degree 120 depending upon the radio coverage area of the source node. using ip address we find the max distance(a) of each zone.after finding max distance can i use aodv protocol to know the destination(d)..simply the distance a to d of each zone using aodv protocol.
    plz help me i am in big problem.

    Hi

    In the beginning thanks for all administrative on this nice blog. I'm M.S.c student and have message about" Traffic Prediction In Cloud Computing", My goal from this message is finding the shortest-path between the source and destination. Now i'm used NS2 and work with wireless network and used AODV for this purpose. Plz can u provide me the code for this. If u can, then where i should put this code in aodv files (AODV.h/.cc) or where?. If u cannot help me, then if u have a code to enhance the end-to-end delay, throughput, ..etc. in AODV?

    Plz if u can help me, then reply me and i will give u my e-mail ok
