Abstract

The invention discloses a method for prolonging the life cycle of a wireless sensor network in an urban comprehensive pipe corridor, comprising: step 1, determining a network topology, step 2, initializing after the network topology is determined, 3, selecting a cluster head node, step 4, forming clusters, and step 5, transmitting data, characterized in that the step 1 comprises simplifying the WSN deployment environment of the urban comprehensive pipe corridor into a long rectangular area A, laying pipes with large energy loss of the sensor nodes in the intermediate path of the long rectangular area A, and laying pipes with gradually smaller energy loss of the sensor nodes from the intermediate path to the two sides of the long rectangular area A. The method for prolonging the life cycleof the wireless sensor network in the urban comprehensive pipe corridor of the invention can effectively prolong the life cycle of the network, and the life cycle of the network is increased by 50% ormore.

Description

technical field [0001] The invention relates to a data transmission method of a wireless sensor network, in particular to a method for extending the life cycle of a wireless sensor network in an urban comprehensive utility gallery. Background technique [0002] The urban comprehensive pipe corridor, also known as the common ditch, refers to the public tunnels used to lay municipal pipelines such as electricity, communications, radio and television, water supply, drainage, heat and gas underground in the city. It is a modern, scientific and intensive Urban infrastructure [11]. Because the power, communication, radio and television, water supply, drainage, heat, gas and other pipelines mentioned in the urban comprehensive pipeline gallery need to be in stable operation, it is necessary to monitor these pipelines in real time to ensure that problems can be found at any time, so that personnel can be dispatched in time Accurately arrive at the fault location for troubleshooting...
