Research On QoS Performance In Mobile Ad Hoc Network

As a new type of mobile wireless networks, Mobile Ad hoc network has its unique network characteristics, widely used in the military field, the earthquake disaster relief and other special areas.But with the development of technology, performance requirements people demand on the network gradually increase, especially in the quality of services on the network layers (Quality of Service, QoS) performance. Firstly, this paper focuses on mobile Adhoc network routing protocols analysis and research and its QoS performance made in detail, propose a protocol to prevent wormhole attacks algorithm OLSR, the more obvious improvements for mobile Adhoc network QoS performance. In addition, the paper analyses MAC layer in mobile Adhoc network problems, and then the actual data packets according to the network forwarding probability distribution, the use of Markov process to its QoS performance made a preliminary analysis, propose a protocol to improve the efficiency of MEMAC. Finally, this paper mobile Adhoc network security service network performance analysis and research, and proposed an active rule set based on the rules of classification, using this method, the effective solution of the malicious packets on the network intrusion detection when it the efficiency, greatly improve the network security.Based on studying the QoS of the Adhoc network, the paper presents great improvement, and solves the practical application problem of poor quality performance.
