Dear all: I want to know where to get the signal strength that Mobile node receive from AP(wireless Access Point). I need it for a threshold. I know it could be found in mac directory,but i am not sure which file is correct. Could anyone tell me where to catch the signal value? And then While current signal strength < default threshold I want to inform tcp layer to trigger function. But I don't know how lower layer to communicate with higher layer. Is funcion call or sendmessage useful? Please recommend me to slove the problems.
