摘要： A method for configuring and managing a multicast data delivery path in a wireless ad-hoc network and a multicast data delivery system using the same are disclosed. The method includes transmitting, by a parent node, first messages to respective child nodes, transmitting, by each of the child nodes, a second message to the parent node in response to the first message relayed by at least some of non-member nodes other than the parent node, performing an operation as a branch node by a non-member node receiving second messages belonging to the same multicast session and transmitted from different originators, and establishing, by the parent node receiving at least one second message, an Internet protocol (IP) tunnel with the originator of the received at least one second message. The performing of the operation as the branch node includes regarding the originators of the received second messages as child nodes, establishing IP tunnels connected to the respective child nodes, generating a new second message including an identifier (ID) of the branch node and IDs of the child nodes in an originator field and a child list field, respectively, and transmitting the generated second message to the parent node.

摘要： Disclosed is a network coding method and system for receivers having a different channel state that may demodulate and extract a single coded packet using a different demodulation scheme according to a channel state of each receiver. The disclosed network coding method may use a different demodulation scheme to be suitable for a channel state of each receiver by applying a packet encoding scheme combined with a modulation scheme. When two receivers receive a network coded packet, a receiver having a poor channel state may receive a relatively small amount of information from the single packet compared to the other receiver having a relatively excellent channel state, but may enhance the reliability of packet reception. The other receiver having the relatively excellent channel state may decrease the reliability of packet reception, but may receive a relatively large amount of information.
摘要翻译：公开了一种具有不同信道状态的接收机的网络编码方法和系统，其可以根据每个接收机的信道状态使用不同的解调方案来解调和提取单个编码分组。所公开的网络编码方法可以通过应用与调制方案组合的分组编码方案，使用不同的解调方案来适合于每个接收机的信道状态。当两个接收机接收到网络编码分组时，具有较差信道状态的接收机与具有相对优良信道状态的另一接收机相比，可以从单个分组接收相对较少量的信息，但是可以提高分组接收的可靠性。具有相对优异的信道状态的另一个接收机可能降低分组接收的可靠性，但是可能会接收到相对大量的信息。

摘要： Provided are a channel management method and a channel selection method for a wireless node in a wireless ad-hoc network. The channel management method includes the steps of: (a) when a current mode is a first mode, performing channel selection using a method for evenly distributing a channel within an interference range; and (b) when the current mode is a second mode, performing channel selection based on a channel switching probability. According to the method, by preventing a channel change from being continuously repeated in a wireless ad-hoc network using multi-channel multi-interface, it is possible to prevent data transmission delay and network performance deterioration.
