Wireless Ad Hoc Routing Protocol Based On The Position Of The Vehicle Information

In the field of mobile communications, Ad Hoc have no center, self–organization, the Interim Self-Government and other features, making thetechnology come to the fore in the mobile communications applications,broadening the prospects for the development and application range ofrelated fields. Ad Hoc network is different from the characteristics of theexisting communications network, a lot of problems still have not been ableto be properly resolved in Ad Hoc Networks, in the research process, routingprotocols, QoS security, expense management, resource management, etc. areAd Hoc Networks in the development of research priorities.Ad Hoc network topology is usually to maintain a dynamic change in itsrouting protocols, QoS, security, expense management, resource managementand other issues relative to other networks to compare complex. Routingcosts and guarantee the quality of data transmission has become an importantissue in the study. The classic Ad Hoc routing protocols such as AODV, DSRalgorithm, the minimum routing hops as a protocol to measure the criteria forthe routing costs in the data transfer process does not give much thought to,and there is no consider the nodes in the external network communicationprocess, due to the dynamic characteristics affect the transmission quality.Along with the continuous advances in hardware, making a seamlesscoverage of wireless signals to become available to achieve operating Thisarticle revolves around the center of ensuring the quality of data transmissioncommunication, a new routing algorithm to adapt to the Ad Hoc network inthe vehicle ’s actual application requirements. The main duties include thefollowing three aspects.First, the study of knowledge, the AODV routing algorithm in-depth study, to grasp the principle of minimum routing hops, including routediscovery and maintenance process.Second, imagine a study for the proposed wireless signal coverage onthe basis of the AODV algorithm is proposed to ensure that the routingalgorithm for Ad Hoc networks in and outside the network for datatransmission communication signal quality. IP address assignment, theprocess steps in the design, add parameter fields to conduct a detailed studyand elaboration, given the solution.Finally, the OPNET network simulation platform for modelingexperiments, the newly designed L-AODV routing algorithm(Location-based Ad Hoc On-demand Distance Vector routing) simulation experiments.Compared with the original AODV routing algorithm in the samecircumstances the same rate as the packet delivery ratio, average end latency,network overhead data, trying to show the performance improvement of thenew routing algorithm. And analysis of network latency and network loadnew routing algorithm L-AODV under different contract interval; rates ofdifferent mobile network delay and network throughput; power routing hopsand routing traffic. Comparisons, the data show that the proposed newalgorithm to ensure accurate small-scale broadcasts the quality of datatransmission communication, combined with dual LAN switch of thinking toachieve the purpose of continuous data transmission. This algorithm by thesimulation results show the higher feasibility of seamless coverage of thewireless network signal environment, the rules of the Ad Hoc in the vehiclesuch a path can be a high predictability of the application, with certainpractical reference value.
