Hi Emma, Handoff attemped means one of your nodes move away from AP range and try to find another AP. To fix it, you can modify the setdest of node or radius of AP. Hope it helps.

RXThresh_ and CSThresh_ in order to reduce the transmission range of a sensor, in fact I want that this transmission range to be equal to 40 meters: Phy/WirelessPhy set RXThresh_?? 11.27918e-08 Phy/WirelessPhy set CSThresh_?? 11.27918e-08 Phy/WirelessPhy set Pt???????? 0.003 But? this modification let the transmission delay of a message so large, for example sending a hello message from a node to another node (the distance between these two nodes is 20 meters)? takes 40 seconds which is so large! Have you please an idea on how to minimize the transmission delay without increasing the transmission range? Thanks for your help __________________________________________________ Do You Yahoo!?
