//TODO part about hello packet in aodvrouting.cc( pleeease help me)

[nilou...@gmail.com]

could you pleeeease help me with your code?
i need to implement in inet the highlight part as follow in aodvrouting.cc

void AODVRouting::handleHelloMessage(AODVRREP *helloMessage)
{
    const IPv4Address& helloOriginatorAddr = helloMessage->getDestAddr();
    IPv4Route *routeHelloOriginator = routingTable->findBestMatchingRoute(helloOriginatorAddr);

    // Whenever a node receives a Hello message from a neighbor, the node
    // SHOULD make sure that it has an active route to the neighbor, and
    // create one if necessary.  If a route already exists, then the
    // Lifetime for the route should be increased, if necessary, to be at
    // least ALLOWED_HELLO_LOSS * HELLO_INTERVAL.  The route to the
    // neighbor, if it exists, MUST subsequently contain the latest
    // Destination Sequence Number from the Hello message.  The current node
    // can now begin using this route to forward data packets.  Routes that
    // are created by hello messages and not used by any other active routes
    // will have empty precursor lists and would not trigger a RERR message
    // if the neighbor moves away and a neighbor timeout occurs.

    unsigned int latestDestSeqNum = helloMessage->getDestSeqNum();
    simtime_t newLifeTime = simTime() + allowedHelloLoss * helloInterval;

    if (!routeHelloOriginator || routeHelloOriginator->getSource() != this)
        createRoute(helloOriginatorAddr, helloOriginatorAddr, 1, true, latestDestSeqNum, true, newLifeTime);
    else {
        AODVRouteData *routeData = check_and_cast<AODVRouteData *>(routeHelloOriginator->getProtocolData());
        simtime_t lifeTime = routeData->getLifeTime();
        updateRoutingTable(routeHelloOriginator, helloOriginatorAddr, 1, true, latestDestSeqNum, true, std::max(lifeTime, newLifeTime));
    }

    // TODO: This feature has not implemented yet.
    // A node MAY determine connectivity by listening for packets from its
    // set of neighbors.  If, within the past DELETE_PERIOD, it has received
    // a Hello message from a neighbor, and then for that neighbor does not
    // receive any packets (Hello messages or otherwise) for more than
    // ALLOWED_HELLO_LOSS * HELLO_INTERVAL milliseconds, the node SHOULD
    // assume that the link to this neighbor is currently lost.  When this
    // happens, the node SHOULD proceed as in Section 6.11.
