Research On Key Technologies Of Low Delay Mobile Ad Hoc Routing

With the development of communication technology and the wide use of wireless communication and mobile terminals,the application scenarios of mobile Ad Hoc networks are becoming more and more common,thus the research on mobile Ad Hoc networks has become more and more important.Under today's environment,nodes in the network often have the characteristics of high-speed mobility,and with the diversity and portability of communication devices,the scale of the network is also increasing.The high-speed mobility of nodes brings in the issue that the topology of network changes frequently,this further causes performance loss of ad hoc networks,therefore the solution to the above issue is critical in the research of Ad Hoc networks.The core of maintaining the normal operation of the network is the design of the routing protocol.At present,the research on the routing algorithm of the Ad Hoc network has already achieved great progress.Typical routing algorithms include AODV,OLSR,DSDV,and ZRP.Each algorithm has its own advantages and is suitable for scenarios with different communication needs.In the case of continuous upgrade and update of the mobile Ad Hoc network,traditional Ad Hoc routing protocol also needs to adapt to the new characteristics of the network to meet the communication requirements of the network under high speed conditions.In this paper,we present a new routing protocol based on the famous position-based GPSR algorithm.In order to sense the mobility of nodes in the network and the communication strength of the network,a new routing scoring mechanism is proposed.Based on this idea,an improved GPSR is proposed.The routing algorithm GPSR-S combines the location coordinates of the network nodes,the velocity and the available capacity of the node's resources to optimize the performance of the routing algorithm.We want to make sure that the performance of the network communication can be guaranteed under high-speed moving scenario,and the low communication latency is maintained.For the algorithm we proposed,this paper also designed experiments for verification analysis,and made a prospect for further research.
