Analysis on the Algorithm of Driven Routing Protocol for Special Frequency Point of Internet of Things

Private Frequency Point Ad Hoc Network of the Internet of Things is applied to power detection and environmental monitoring. The network is composed of multi-hop convergence tree routing network. However, the energy consumption of network nodes tends to be unbalanced, and link failure occurs when the number of nodes increases. Aiming at this problem, an algorithm for improving the IoT dedicated frequency point ad hoc network drive routing protocol is designed. Based on the perception of the scene, the aggregation node and the Internet as the main structure, the IoT-dedicated frequency-point self-organizing network model is constructed. The model uses MPR set to select node mechanism synthetically. Based on the sum of total energy consumption and energy cost of network nodes, the objective function of nodes is optimized to ensure the energy of Ad hoc network. Consumption is in a balanced state; through the improved algorithm of network routing protocol, the minimum coverage set is used to repair the link failure of ad hoc networks with dedicated frequency points in the Internet of Things. The results show that the proposed algorithm has good throughput performance for routing link information forwarding, improves network data transmission and connectivity, increases node lifetime, improves data packet arrival rate and controls data volume.
