Key Technology Research In Mobile Ad Hoc Network Base On Game Theory

Mobile Ad Hoc network is a multi-hop temporary autonomous system. It is convenient andrapid to form a network. However, due to the selfish characteristics of the composed nodes in thenetwork, the network encounters much more challenges than the wired or other wirelessnetworks in the fields of data forwarding, etc. In wireless ad hoc networks, mobility and dataflow model is very complex; topology changes dynamically; link quality is unpredictable. Thearticle analyzes existing protocols, the resource management mechanisms, as well as aequilibrium induction mechanism via the use of game theory. And use game theory to studysome key technologies.The article mainly includes(1) Analyzes and studies related game theory; and according to the knowledge of gametheory and features of mobile ad hoc networks, analyszes and establishes game-theoreticstrategies that are suitable for the data forwarding between layers of a mobile ad hoc network;Also, corresponding game-theoretic models of the physical layer, media access layer, networklayer and the transport layer of a mobile ad hoc network are given. Based on the aforementionedresearch, analyzes and studies two types of incentive mechanisms: the credit exchanging systemand the reputation-based system. On this basis, analyzes and studies these two incentivemechanisms in mobile ad hoc networks.(2) Studies and proposes an adaptive reputation-based mechanism based on game theory.On the basis of analysis and research of related game-theoretic incentive mechanisms, proposean adaptive game mechanism for data forwarding between mobile nodes in a mobile ad hocnetwork. The mechanism is to achieve:(a) to endeavor to procure nodes in the network tocomply the determined routing strategy;(b) not to apply retaliation to the uncooperative node;instead, exclude them from being the source node while they can still forward data;(c) toencourag nodes with mistakes to rehabilitate. And at the same time analyzes and studies thepotential "collusion" between mobile nodes.(3) The data replication technique is the solution to ensure that data continues to be validwhen the network source data node becomes unavailable. Studies how to achieve data replicationtechnique in the mobile ad hoc networks where the network topology changes, and also solvesthe problem of data replica placement considering selfishness of the mobile nodes. The study aims to implement how to adopt bid theory in game theory to solve the problem of datareplication.(4) Due to the dynamic topology changes and autonomous mobility of mobile nodes inmobile ad hoc networks, the transmission route re-links frequently, which will interrupttransmission. When the network is required to provide stable routing services for applicationsthat demand real-time performance and integrity (distributed computing), how to select theappropriate relay node for this route and what conditions to choose accordingly remaining aproblem. The article provides a detailed analysis and study of these problems, and proposes thealgorithm to implement. Thus it provides stable and robust routing services for the networks thatserve applications demanding real-time performance and integrity (distributed computing).
