| Popis: | 101 In this thesis, a 3D-Mesh formation method is proposed. The types of 3D-Mesh architecture were divided into triangular-shaped, quadrilaterals, pentagons and hexagons. The number of layers can be generated from level 1 to level 8. The type of its interconnection bridge contains RmS(Ring Inter-mesh Slave)、RMS(Ring Intra-mesh Slave)、and RmMS(Ring Mesh Slave). Scatternet formation procedures include two stages. The first stage is to select a BlueRoot, First, any two nodes with random probability to enter the inquiry or inquiry state and the inquiry node keeps the information of the other node. Then the inquiry node starts the probability decision again to enter either the inquiry or inquiry scan state. The step is repeated iteratively until the last node called BlueRoot is generated. In the second stage, BlueRoot computes the scatternet topology according to the predefined formula and passes the piconet information to the other masters. Each master pages and connects its slave and bridge to form its piconet until the scatternet is formed. The predefined formula can be deduced according to the number of nodes and the hierarchical relationship. In addition, an optimum method by the simulation results is designed to achieve the lowest hop length of 3D-Mesh topology. Computer simulation is performed to generate the performance metrics including the average hop length, throughput, packet delay, and packet delivery ratio. The performance results show that 3D-Mesh Network achieve good scatternet performance for the Bluetooth-based ad hoc networks. |
