qos routing mechanism using mobility prediction of node in ad-hoc network
MANET(Mobile Ad hoc NETwork) consists of movable only wireless nodes, except fixed station in the wired network. Not only hosts, but also routers for data packet forwarding in network topology changes. It is hard for routing algorithm using previous wired network to be applied to this ad hoc network. In the beginning, table-driven algorithm such as DSDV was shown in MANET, which resulted researches of On-demand routing protocols such as DSR, supporting mobility for mobile terminals. Recently, a routing protocol was developed, combined advantages of the former and the latter, called AODV(Ad hoc On-demand Distance Vector). However, despite advantages of AODV, it makes overall network performance weak due to nodes that move frequently, resulting considerable routing control traffic. In this paper, we propose efficient routing mechanism with route prediction of nodes for link reliability in MANET. Our work collects routes from source to destination with AOMDV. In this process, each node with GPS (Global Positioning System) predicts to move expected location by calculating node's location and velocity. With this mechanism, it makes source node can decide the route which has the longest connection time. And due to the reason why the node can choose appropriate route to data property among multiple routes collected to AOMDV, it also can reduce unnecessary control messages in MANET. By NS2 simulation, we analyze the former routing protocols to demonstrate the superiority of our work.
