Abstract: A distributed channel allocation method and a wireless mesh network with the same are provided herein. By the distributed channel allocation, interference situations are avoided in a wireless network communication, and the allocated bandwidth can then be fully utilized. Besides, unnecessary depletion of an allocated bandwidth due to the interference can be avoided. By this method, a time division technique is applied for dividing a transmission time of each wireless NIC, and different non-overlapping channels can be assigned to different timeslots. Different from other researches that require a symmetrical number of the NICs between a receiving node and a transmitting node, in this method, a unique wireless NIC may communicate with the wireless NICs. The method provides the feature that the number of the NICs on a certain node can be adjusted to meet a communication requirement, by which the efficiency of a network flow is also significantly improved.

Abstract: A method for routing data, using a stateless routing protocol includes communicating data between a source host and a destination host in a network with a plurality of hosts. Each host in the network has a unique numerical address. The method comprises determining a least common ancestor host of the source host and the destination host using the unique numerical address of each of the source and destination hosts. The data is sent from the source host to the least common ancestor host, and then sent from the least common ancestor host to the destination host. Alternatively, the data can be routed using a stateful routing protocol in which each host records the address of its neighbors and forwards the data to the neighbor host that is closest to the destination host.

When the power-based scheduler schedules the PDUs, if the total sum of the required power of the PDUs exceeds the maximum power-strength of the wireless communication system, the power-based scheduler sends back to the time-based scheduler the PDUs whose power amounts to the exceeding of the maximum power-strength of the wireless communication system according to the corresponding priority values of the PDUs, so that the wireless communication system transmits all at a time the remaining PDUs whose total power remains within the maximum power-strength.

Abstract: A method and system for applying a multi-protocol label switching (MPLS) network to support QoS in general packet radio service (GPRS) is disclosed. An E-LSP tunnel with reserved bandwidth is pre-configured between Gateway GPRS Support Node (GGSN) and each Service GPRS Support Node (SGSN), and between any two SGSNs. Before an Mobile Station (MS) wishes to transmit or receive packets, it need to ask its designated SSGN for establishing an on-demand L-LSP from the SGSN to the Corresponding Node (CN). This L-LSP is required to tunnel through the pre-configured E-LSP that was mentioned above and here we apply the label stack technique from MPLS. Therefore, the packets of the on-demand L-LSP can be tunneled through the pre-configured E-LSP to the SGSN in which the MS is located, and then the SGSN is able to recognize and locate the mobile station according to the corresponding label in on-demand L-LSP.
