Abstract:
A wireless mesh network (WMN) scheduling method based on a bio-inspired algorithm is provided. The WMN scheduling method includes updating statistic information about channel occupancy statuses and statistic information about channel assignment determination maximum values through an ant packet, assigning a channel, which meets secondary interference constraint, using the channel assignment determination maximum values and assigning a link activation time, and repeatedly performing the processing from the updating of the statistic information until the channel is assigned to all links of a node.
Abstract:
Provided is a terminal, for example, user equipment (UE), including a processor and that performs a random access (RA) procedure with a base station, for example, for example, eNodeB, E-UTRAN Node B, or also known as Evolved Node B, and is at least temporarily embodied by the processor. The terminal may be at least temporarily embodied by the processor. The terminal may include a generator configured to generate a preamble sequence using a first sequence corresponding to a first root index based on a preamble index that is randomly selected, and a determiner configured to determine a second root index using the preamble index as an input value of a root index function. Further, the generator may be configured to generate a tag sequence using a second sequence corresponding to the second root index based on a tag index that is randomly selected.
Abstract:
A cross-layer framework in a wireless mesh network using a bio-inspired algorithm and an operation method thereof are provided. The cross-layer framework includes a data structure configured to be formed in each node of the wireless mesh network and to collect and update information of each node through an ant packet and a cross-layer unit configured to perform at least one or more of channel assignment, routing, link scheduling, buffer management, and frame scheduling with respect to a control data flow of the data structure and to dynamically assign channels.
