Abstract: Based on the IEEE-802. 15. 4 standard and WIA-PA networks with VCR in it, the minimum hop routing algorithm and energy-efficient routing algorithm in wireless networks were introduced. The advantages and disadvantages of the two algorithms were analyzed and compared. By combining the minimum hop routing algorithm and routing algorithm for energy-saving advantages as well as VCR in the WIA-PA network, a routing algorithm based on the VCR was designed and simulated. Simulation results show that the novel routing algorithm based on VCR with combing the two traditional routing algorithms is efficient. By comparing the WIA-PA VCR application with different routing algorithms, it achieves lower delay management data packet forwarding and energy consumption of data packets transmitting, and is more suitable for the WIA-PA network applications.
