Abstract

The invention discloses a residual energy sorting load scheduling method and a residual energy sorting load scheduling system. The method comprises the following steps: step one, solving (alpha(1), alpha(2),..., alpha(n)) based on a typical divisible load scheduling algorithm, wherein alpha(i) represents a task; step two, sorting nodes in order by taking the residual energy of each node as a keyword to construct a new sequence (beta(1), beta(2),..., beta(n)), wherein beta(1), beta(2),..., beta(n) correspond to the nodes in a network; and step three, sequentially assigning the tasks (alpha(1), alpha(2),..., alpha(n)) to the nodes which are sorted in step two. According to the invention, the energy efficiency is greatly improved and the life cycle of the whole wireless sensor network is prolonged on the basis that the resource load is not increased obviously.

Description

technical field [0001] The present invention relates to a method and a system for improving network performance by utilizing a load distribution protocol (REOS) of a wireless sensor network, in particular to a method and a system for scheduling loads of a wireless sensor network with residual energy sorting. Background technique [0002] Wireless sensor network (Wireless Sensor Network, WSN) refers to an ad hoc network composed of a large number of tiny sensor nodes deployed in the monitoring area. WSN has been widely used in environmental monitoring and telemedicine and other fields. Micro sensor nodes in WSN usually have the functions of information collection, data processing and wireless communication, but due to the influence of volume and monitoring environment, the nodes can only carry limited energy. In order to prolong the life cycle of the network, balancing the remaining energy of each node in WSN has become one of the research hotspots. [0003] As we all know,...
