hi, I'm just simulating the GPSR patch for ns-2.34. I find some intersting results: 1)for this patch, there is no localisation service used 2) the most important, the protocol doesn't consider the mobility of nodes: I simulate 2 nodes X(10,1,0) and Y(270, 1, 0) with transmission range 250m I moved the Y to the range of X but Y still don't receive data sent from X so can anyone tell me what to do because I need to make simulation with mobile nodes thkx
