Improved QoS Routing Model with Local Information of Network State

Abstract

QoS (Quality of Service) routing algorithm based on localized information has recently been proposed as an alternative approach to the traditional QoS routing algorithms that use global state information. By this method, the localized algorithm, using information collected from source node, helps flow routing better and assures QoS more flexibly for network. This kind of scheme will be able to become a new solution for satisfying the higher and higher demand of telecom services in the near future. In this paper, we introduce a new routing algorithm, an effective localized QoS routing which can be used to assure the quality of network, and show our simulations that perform better results than other routing algorithms.
