A method and an electronic device for controlling a topology are provided. The method includes forming a star topology by directly connecting the electronic device to at least one node, and transmitting and receiving signals with neighboring nodes including the at least one node and determining whether to form the star topology or an extended star topology with the neighboring nodes based on a result of the transmitting and receiving, wherein the star topology is a topology in which the electronic device is directly connected to the neighboring nodes, and wherein the extended star topology is a topology in which the electronic device is directly connected to the neighboring nodes via an already connected node.

Method and apparatus for controlling topology

Provided is an apparatus to detect congestion of a network using a receiver of a communication system. The apparatus includes a transport layer information extraction unit configured to extract transmission control protocol frame information from information that is received from a lower layer. The apparatus also includes a congestion information filtering unit configured to identify and output a packet to determine congestion in the transmission control protocol frame information. The apparatus further includes a congestion detection unit configured to determine whether the network is congested using the packet to determine congestion. The apparatus includes a congestion information output unit configured to, upon detecting congestion in the network, deliver information indicating the detection of the congestion in the network to an operating system or other applications.
