Balanced energy consumption based data routing method for haze environment monitoring network

Abstract

The invention discloses a balanced energy consumption based data routing method for a haze environment monitoring network. The method disclosed by the invention comprises the steps of dynamically dividing different network nodes into different index domains by building an index function related to distance and energy consumption parameters; judging whether a next-hop node to be selected is the next-hop node or not by judging whether the next-hop node to be selected belongs to a low index domain and an index function value of the next-hop node to be selected is maximum and nearer to a target node or not; and taking the next-hop node to be selected as the next-hop node to perform data forwarding when the next-hop node to be selected belongs to the low index domain and the index function value of the next-hop node to be selected is maximum and nearer to the target node. By adopting the method, sensor nodes in a network are dynamically divided by building the index function, and the forwarding tasks is relatively evenly distributed during the data forwarding by calculating the index values of the corresponding nodes, so that the risk that the energy consumption of a single node is too fast is reduced, and the goal of balancing the energy consumption of all the network nodes is reached. By adopting the method, the build of the network nodes is agile and changeable, and the requirement on monitoring the haze environment can be better satisfied.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring, and in particular relates to a data routing method based on energy balance for a smog climate environment monitoring network. technical background [0002] In recent years, the occurrence frequency of smog in Chinese cities has become higher and higher. According to monitoring, in 2004, Guangzhou, China had 144 days of smog throughout the year, and Shenzhen, China had 175 days of smog throughout the year. By 2007, Guangzhou had 153 days of smog throughout the year, while Shenzhen had reached an astonishing 231 days. In recent days, especially at the end of 2012, smog broke out across the country for many months, and the air quality in the capital Beijing dropped to the lowest value in recent years, and the daily life of the people was greatly affected. These data can clearly reflect the trend of more and more severe haze weather in recent years. [0003] The causes and treatmen...
