摘要： A packet communication system etc., is proposed, which can automatically adjusting the antenna directionality without modifying a wireless interface of a wireless packet forwarding device even if it involves fluctuation in the packet transmission timing due to CSMA/CA etc. An interference evasion unit involves fluctuation in packet transmission timing due to CSMA/CA. A radio emission device can control the emissive direction and/or emission intensity. A packet generation unit adjusts packet features other than its contents (e.g., packet length, transmission intensity) based on a switching sequence for specifying the emissive direction and/or emissive intensity, and generate a switching control packet. An emission control unit measures the switching control packet feature other than its contents, and identifies at least one bit as antenna control information. The emission control unit controls the overall directionality of a directional antenna unit based on a bit sequence including at least one bit thus identified.

摘要： Provided are a communication system and the like capable of making a stable relay route even when a propagation channel is fluctuated by the fluctuation of RSSI. For making a tree-type communication route whose root is a core node, each slave node, after the reception of the latest reset routing packet from a node, judges if the transmission source node should be the parent of the tree-type structure based on the sequential average of the reception power of n routing packets received from the same transmission source node. As the reception power is log-normally distributed in general, an asymptotically stable relay route can be obtained, especially by using the sequential average.

摘要： A radio network can select a route of minimum path loss among entire relay routes and can set the relay route so as to satisfactorily resist interference. The radio network has a core node connected to a wired network, relay nodes each relaying at least one of a down-link data packet transmitted from the core node and an up-link data packet directed toward the core node, and a terminal station capable of transmission and reception of data packets with both the core node and the relay node. The relay node has total path loss optimized to be minimum between relay nodes included in a relay route of the data packet or between the relay node and the core node or both.
