Abstract: A method for determining time to live (TTL) of a path of a node including receiving a routing control packet, which includes a first link quality indicating a link quality of a path from the neighbor node to a source node transmitting the routing control packet, from a neighbor node of the node, acquiring a third link quality indicating a link quality of a path from the node to the source node according to a second link quality indicating a link quality of a path from the node to the neighbor node and the first link quality, and determining the TTL of the path from the node to the source node according to the third link quality may be provided. Accordingly, the TTL of the path can be determined more accurately according to a link quality of the path, thereby contributing to ensuring performance and stability of a routing algorithm.

Abstract: An indirect data transmission method may include: calculating an estimated arrival time of a next poll data request of a terminal device according to a receipt time of a poll data request, after the poll data request is received from the terminal device; transmitting data for the terminal device to a cache of a Media Access Control (MAC) layer module at a time point which is a predetermined time length ahead of the estimated arrival time responsive to a determination that there is the data for the terminal device in a network layer module; and transmitting, to the terminal device, an acknowledgement packet indicating that there is the data to be transmitted in the cache of the MAC layer module and the data for the terminal device, responsive to receiving the next poll data request.

Abstract: A method of wirelessly transmitting data by a first electronic apparatus configured to initially perform communication using a first wireless communication manner, includes: the first electronic apparatus determining whether performing data transmission through a second wireless communication manner is required; the first electronic apparatus sending a data transmission request message through the first wireless communication manner when it is determined that performing data transmission through the second wireless communication manner is required; and the first electronic apparatus performing data transmission with a second electronic apparatus through the second wireless communication manner after a data transmission acknowledgement message is received from the second electronic apparatus through the first wireless communication manner. The data transmission request message includes indicating information indicating the first electronic apparatus desires to perform the data transmission using the second wireless communication manner.
