Member Function Documentation

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

Called upon arrival of a self messages. The only self message possible is to indicate a new movement. If host is stationary this function is never called. Reimplemented from BasicMobility. { move(); updatePosition(); if (!stationary) scheduleAt(simTime() + updateInterval, msg); }

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

Initializes mobility model parameters. Reimplemented from BasicMobility. { BasicMobility::initialize(stage); EV << "initializing LinearMobility stage " << stage << endl; if (stage == 0) { updateInterval = par("updateInterval"); speed = par("speed"); angle = par("angle"); acceleration = par("acceleration"); angle = fmod(angle,360); // 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 LinearMobility::move (   )  [protected]

Move the host. Move the host if the destination is not reached yet. Otherwise calculate a new random position { pos.x += speed * cos(PI * angle / 180) * updateInterval; pos.y += speed * sin(PI * angle / 180) * updateInterval; // do something if we reach the wall Coord dummy; handleIfOutside(REFLECT, dummy, dummy, angle); // accelerate speed += acceleration * updateInterval; if (speed <= 0) { speed = 0; stationary = true; } EV << " xpos= " << pos.x << " ypos=" << pos.y << " speed=" << speed << endl; }
