A controller apparatus of this invention includes a topology information managing unit configured to manage topology information showing a topology, a location information acquiring unit configured to acquire location information on a plurality of mobile terminals, a link information acquiring unit configured to acquire link information at the mobile terminals, a determining unit configured to determine a way to change the topology, based on the location information, the link information and the topology information, and a transmitting unit configured to generate instruction information for changing the topology, based on the determined way to change the topology, and to transmit the instruction information to a certain mobile terminal.
摘要:
A controller apparatus is configured to control an ad hoc network formed by a plurality of mobile terminals. The controller apparatus includes a transmission power determining unit configured to determine transmission power of a certain mobile terminal joining in the ad hoc network, based on traffic distribution in the ad hoc network.
摘要:
A controller apparatus of this invention controls transmission of a packet from a source mobile terminal to a destination mobile terminal through one or more relay mobile terminals in an ad hoc network formed by a plurality of mobile terminals. The controller apparatus includes a packet location information managing unit configured to manage packet location information which shows to which mobile terminal the packet has been transmitted in the ad hoc network.
摘要:
A routing method in an ad hoc network formed by a plurality of mobile terminals includes receiving, at a mobile terminal forming part of the ad hoc network, a packet generated by an adjacent terminal, and determining, at the mobile terminal, whether to relay the received packet or not, based on presence or absence of a record of packet relaying by the adjacent terminal.
摘要:
A mobile communication system is constructed including a plurality of cluster heads, cluster members, a topology management device, and a location management device. Each cluster head exchanges routing information with only each cluster member in a cluster to which the terminal itself (host terminal) belongs, and with only a cluster head in another cluster adjacent to the cluster to which the host terminal belongs. Each cluster member exchanges routing information with only a cluster head in a cluster to which the host terminal belongs. The topology management device and location management device receive the routing information from each cluster head only.

摘要:
A mobile terminal in a mobile communication system in which a server performs routing control based on registration information sent from the plurality of mobile terminals, including; an exchanging unit configured to exchange, with another mobile terminal, link information showing a link set in the another mobile terminal, and operational information showing whether the another mobile terminal is operating as a registering terminal which sends the registration information to the server or the another mobile terminal is operating as a non-registering terminal which does not send the registration information to the server; and a judgment unit configured to make a judgment on whether the mobile terminal should operate as the registering terminal or the mobile terminal should operate as the non-registering terminal, based on the link information and the operational information which are received from the another mobile terminal.
摘要:
In a wireless communication terminal, the other terminal existence confirmation section broadcasts a confirmation message at fixed intervals and receives a response message. The topology information management section computes the topology of the whole network to which the wireless communication terminal itself belongs, on the basis of the topology information on the network received at fixed intervals from other terminals. The path management section derives an optimum path to the terminal of the transmission destination. The QoS information collection section issues a communication start request instruction and, when a QoS information collect request instruction has been issued, unicasts a QoS request packet on the path and receives a reply QoS request packet. The judgment section adopts the path as the communication path when QoS information satisfies a predetermined quality standard.
