Latest Patents

One of Meng Zheng's latest patents is a resource allocation method for the coexistence of multiple line topological industrial wireless networks. This invention tackles the coexistence problem of multiple TDMA-based line topological industrial wireless networks. It includes three main components: lower bound analysis of scheduling delay, allocation algorithm of inter-network resources, and allocation algorithm of intra-network resources. The method employs overall scheduling delay and resource utilization ratio as measurement indexes to analyze the lower bound of delay and design resource allocation algorithms. It selects the best node combination in each time slot to maximize channel resource usage, thereby improving resource utilization and reducing overall scheduling delay.

Another significant patent is a medium access control method based on broadcast preamble sampling for cognitive sensor networks. This invention relates to cognitive wireless sensor network technologies. It introduces a periodical dormancy-awakening mechanism for cognitive nodes. The method involves judging the state of a primary user using spectrum sensing technology. If the primary user is inactive, a data sending node establishes a communication link using a broadcast preamble code. Neighbor nodes consider hop information from a gateway and independently decide to serve as relay nodes for data forwarding. The invention also incorporates a retransmission mechanism based on confirmation to ensure reliable transmission of data packets, independent of a common control channel.
