TL;DR: In this article, a mesh routing method for beacon-enabled wireless AD-HOC networks is proposed, which includes: broadcasting, by nodes constituting a wireless ad-hoc network, a beacon message loading neighbor node information on a beacon payload; managing, by a node receiving the broadcasted beacon message, its own neighbor node table by extracting the neighbor nodes information loaded on the beacon payload.

TL;DR: This paper proposes the design and implementation of a remote monitoring and controlling system using ZigBee networks that targets a home network and uses a smartphone as a terminal device.

TL;DR: In this article, a multi-path routing method for selecting appropriate multiple paths when information sensed from a source node is transmitted to a sink node in wireless sensor networks is provided, where priorities can be provided to lifetime of the source node, average energy consumption and the shortest path by adjusting the respective weights when routing the plurality of paths.

TL;DR: In this article, a low power routing method using a reservation scheme and an apparatus for performing the time synchronization method are provided, where a first synchronization request command packet from a parent node manages time synchronization for a predetermined synchronization region.

TL;DR: In this article, a method of synchronizing time for a multihop sensor network is proposed, where receiving nodes accurately synchronize time by adding a delay transmission time value to a beacon frame in a beacon mode, or by using a time synchronization frame and time synchronization acknowledgement frame containing time information and superframe structure information in a non-beacon mode.
