Research On Dynamic Offloading Technology Of Intelligent Node Computing Task In Ad Hoc Networks

Ad Hoc network is a dynamic,flexible and autonomic network system,which realize the communication between intelligent nodes through temporary networking way.Because there is no fixed network infrastructure and itself self-healing and invulnerability is strong,Ad Hoc network has become a hot research topic in the field of mobile communication in the future.The popularization and generalization of Rich Mobile Application and Virtual Reality requires intelligent node has higher performance.Computation Offloading focus on solving the prolems of intelligent node of limited resources and Rich Mobile Application demand does not match,the usage of computing resources between nodes are unequal.For example,energy and time consumption of Ad Hoc network is inequality and reducing the survival time of intelligent node etc.The application of Computation Offloading in Ad Hoc network has become a hot topic among experts and scholars in recent years.This paper established five kinds of Computation Offloading mathematical models based on the quantitative relationship of intelligent nodes in Ad Hoc network,before this,we had made a deep investigation on the application of computation offloading in Ad Hoc network and the type and performance parameters of intelligent node.The offloading strategy of low energy consumption and low delay and the Computation Offloading strategy of persistence of Ad Hoc network saturation time are proposed,which solve the problems of the incorrect usage of computing resources and the short survival time of intelligent node in Ad Hoc network.The computation offloading strategy of low energy consumption and low delay,on the basis of different mathematical models of computation offloading in Ad Hoc network,the algorithm based on permutation and combination method and the method of node matching based on Hungarian algorithm are proposed.Taking the energy and delay of the Ad Hoc network as the research goal,we solve the problems of wasting network resources and unequal using the resources of Ad Hoc network by reducing the energy consumption and the time delay.We realize this computation offloading strategy by simulation and the result shows that this strategy has the advantages of saving the energy of the Ad Hoc network and improving the response rate of the intelligent node,energy and time resources were saved by about 13.89%.Every intelligent node in the Ad Hoc network has the necessity of existence,this paper proposed offloading strategy of persistence of Ad Hoc network saturation time,which aim at the lifetime of each intelligent node.Based on different mathematical models of Computation Offloading in Ad Hoc network,the algorithm based on permutation and combination and the method of node matching based on ordering are proposed.Taking the saturation time of Ad Hoc network as the research objective,it solved problem of unbalanced computation task and short lifetime of intelligent node in Ad Hoc network.Realizing the computation offloading strategy of persistence of Ad Hoc network saturation time with MATLAB simulation platform,the results show that the strategy can weigh the load capacity of nodes and improve the survival time of intelligent node,the maximum saturation time is up to 21 times.The low energy computation and low delay offloading strategy and the computation offloading strategy of persistence of Ad Hoc network saturation time are proposed in this paper have certain value and significance for the theoretical research and engineering practice of the application field.
