Method and apparatus for routing in wireless network

A method of routing in a wireless network, which is performed by each of a group of nodes, the method comprising:

• receiving a routing request signal;
• determining whether a node itself is a destination node, by referring to a traffic distribution table showing traffic throughput of the group of nodes and an intermediate-node weight table showing weights of intermediate nodes on all paths between the group of nodes and a source node, wherein a route path is selected by referring to the weights of intermediate nodes;
• and
• when it is determined that the node itself is the destination node transmitting a routing response signal to the source node that has transmitted the routing request signal, and receiving a packet from the source node,
• wherein the transmitting and receiving are performed by the determined destination node,
• wherein the transmitting of the routing response signal to the source node comprises:
• collecting the routing request signal for a predetermined time period;
• when the predetermined time period has passed, determining whether the destination node is a node having the smallest traffic throughput in the group of nodes, by referring to the traffic distribution table;
• when the node determines itself as the destination node, selecting the route path by referring to the intermediate-node weight table, wherein the selecting is performed by the destination node;
• and
• transmitting the routing response signal to the source node through the selected route path, wherein the transmitting is performed by the destination node.
