| Summary: | 碩士 === 中華大學 === 電機工程學系 === 107 === The Bluetooth scatternet provides a low-interference transmission environment for communication between Bluetooth devices and communication over multi-hop links. Most current decentralized network formation protocols tend to interconnect all Bluetooth devices and maintain all links during the initial network startup phase. The benefits of this design can reduce the time it takes to find routes and instantly transfer data to the destination node.
In order to increase system capacity and reduce packet delay and the structure of the loose mesh can be formed according to the needs of the user. Solve the problem of mismatch in scatternet structure, this paper proposes a distributed construction for Cellular Topology. Which includes node discovery, piconet configuration and regional sprawl formation process, then combine the regional scattered networks into a whole network architecture. And solve the structural mismatched link and route maintenance.
Based on the simulation results of Matlab software, the distributed construction topology proposed in this paper is effectively improved in the packet throughput compared with the CORP topology, and is significantly reduced in the packet delay. As a result, the distributed construction topology proposed in this paper can achieve better network performance than the CORP topology for a multi-hop Bluetooth networks.
