Abstract
A LoWMob (LoWPAN Mobility: Low power Wireless Personal Area Network) system comprises a mobile node, at least one sensor node, a border node and a gateway. The mobile node configured transmits at least one data packet within an MST (Maximum Sleep Time). The mobile node corresponds to an FFD (Full Function Device) or an RFD (Reduced Function Device). The at least one sensor node is configured to be densely to a degree that a transmission range overlaps and configured to be able to measure a moving direction of the mobile node. The boarder node is configured to be arranged at a periphery of the PAN and configured to turn off a transceiver in a quasi-sleep state. The gateway is directly connected with a first least part of the at least one sensor node.
