In networks supporting Mobile IP (MIP), the address configuration of a Mobile Node (MN) is an important part of the handoff process, which is based on the detection of movement between different subnetworks. The movement detection in wireless IP network is usually performed by means of Router Advertisement (RA) messages which are sent with a fixed and constant period. The higher is the rate of these messages, the lower the handoff delay is and the higher is the bandwidth occupation on the wireless medium. To trade off these values, we propose a method to decrease the bandwidth occupation of movement detection messages while confining part of the L3 handoff setup latency under acceptable values, for instance 15 ms ÷ 40 ms. The benefit on the bandwidth occupation with respect to the constant rate technique is between 25% ÷ 40%, depending on the interval of advertisement messages. Our technique is based on the windowing of the RA messages trains, each window being placed at the predicted time instants of handoff arrivals.
