Member Function Documentation

void CircleMobility::handleSelfMsg (  cMessage *  msg  )  [protected, virtual]

Called upon arrival of a self messages. Reimplemented from BasicMobility. { move(); updatePosition(); scheduleAt(simTime() + updateInterval, msg); }

void CircleMobility::initialize (  int   )  [protected, virtual]

Initializes mobility model parameters. Reimplemented from BasicMobility. { BasicMobility::initialize(stage); EV << "initializing CircleMobility stage " << stage << endl; if (stage == 1) { // read parameters cx = par("cx"); cy = par("cy"); r = par("r"); ASSERT(r>0); angle = par("startAngle").doubleValue()/180.0*PI; updateInterval = par("updateInterval"); double speed = par("speed"); omega = speed/r; // calculate initial position pos.x = cx + r * cos(angle); pos.y = cy + r * sin(angle); updatePosition(); // if the initial speed is lower than 0, the node is stationary stationary = (speed == 0); // host moves the first time after some random delay to avoid synchronized movements if (!stationary) scheduleAt(simTime() + uniform(0, updateInterval), new cMessage("move")); } }

void CircleMobility::move (   )  [protected]

Move the host. { angle += omega * updateInterval; pos.x = cx + r * cos(angle); pos.y = cy + r * sin(angle); EV << " xpos= " << pos.x << " ypos=" << pos.y << endl; }
