Research On A Secure And Energy-efficient Routing Protocol For Ad Hoc Networks

Ad Hoc network is a kind of self organization,there is no central multiple hops network.Aiming at security problems of energy saving of mobile Ad Hoc network,this paper proposes An Security and Energy Optimization Ad Hoc Routing Protocol(SEOARP).This paper introduces the research background,significance and research status at home and abroad of the energy saving and the security of the Ad Hoc network,Doing some resear ch in the following two aspects:(1)In terms of energy saving in Hoc Ad network,Compared the current several kinds of typical routing protocols,through the perspective of energy equilibrium,it introduces the Lorenz curve of the famous American statistician to measure the energy consumption of network equilibrium,Synthetically considering the network communication among each node of the busy degree.According to the existing network node can lay aside,from low to high order residual storage for each node can come to the lorenz curve.And it is concluded that measurement residual storage nodes can measure unfair distribution of the Gini Coefficient(Gini Coefficient).On the basis of the residual rate of gini coefficient to get the node energy storage.When making routing,combining comparing network gini coefficient and the residual storage nodes,it can choose the routing ink remaining the most storage energy.it achieves energy balance.,and saving-energy objective.(2)In the aspect of safety,By comparing the advantages and disadvantages of the currentAd Hoc secure routing protocol encryption algorithm,This paper cites a improved lightweight elliptic curve ECC key algorithms,which sets an elliptic curve identification and digital signature authentication as scheme that provides end-to-end,point-to-point routing certification.To achieve the purpose of secure routing.Simulation results show that the proposed security routing protocol also have a greater improvement in transmission performance of data,packet loss rate when malicious nodes attack,node energy consumption and so on indicators.
