The technical field of wireless sensor network anycast routing of the present invention is specifically an anycast routing method for wireless sensor networks based on the DV-hop algorithm, which solves the problems of network delay, short network survival time, and uneven network energy consumption in wireless sensor networks , the method of the present invention first utilizes the DV-hop algorithm to calculate the specific position of P, then selects the optimal transmission path between P and the nearest sink node, and finally P sends according to the hop number of the optimal transmission path and according to a certain weight ratio Data packets, so it can reduce network delay, reduce sending time; balance node energy consumption, reduce network energy consumption; improve overall network survival time.
Description
technical field [0001] The invention belongs to the technical field of wireless sensor network anycast routing, in particular to a wireless sensor network anycast routing method based on a DV-hop algorithm. Background technique [0002] In recent years, the Internet of Things technology has continuously achieved new achievements, and has been applied to the fields of national defense and military, environmental monitoring, traffic management, medical and health care, manufacturing, disaster relief and emergency rescue. As one of the important underlying technologies of the Internet of Things, wireless sensor networks have become a research hot spot. Among them, anycast routing technology is a very important research technology in wireless sensor network. In the wireless sensor network, because the energy of the sensor node comes from a limited power source (battery), the node's computing and storage capabilities are weak, and the sending of data packets consumes energy, so ...
