January 2007 doc. : IEEE 802. 15 -07 -0576 -00 -0 ban Characteristics of U-Parking Lot Service (2/2) • Devices are moving fast! (at least 30 Km/h) – Reassociation should be avoided due to the fact that there can be heavy unnecessary association request traffic. – The network address shall be the same for any position. • Traffic Directions – Every traffic from both sensor nodes and the mobile terminal is toward the MPC. – The delivery of the traffic from the MPC to the incoming cars requires fast routing using the RREP type of AODV-like simplified reactive routing algorithm is required and possible. – No need to send RREQ by MPC, rather RREP sent directly by the moving cars. • Disassociation request before leaving the network will be very important for address space reusability.
