Energy-efficient data forwarding strategy in intermittent connected wireless networks

In intermittent connected wireless networks,the energy resources of nodes are limited and the link duration is short,so the network resources cannot be fully used. This article introduces a data forwarding strategy with an adaptive asynchronous wakeup schedule,which synthesizes the energy consumption and dormancy mechanism of nodes,combines with the gray model to forecast the inter-node meeting duration,thus optimize the energy consumption of nodes in the detection and data forwarding phase,and finally achieves the purpose of efficient data forwarding. The results show that the proposed data forwarding strategy can effectively utilize the residual energy and communication opportunity of nodes. Compared with the existing forwarding strategies,this strategy can effectively improve the detection rate and communication time delay of the networks under low energy consumption.
