QoS Routing Algorithm For Wireless Networks

Wireless Sensor Network (WSN) is a novel technology about acquiring and processing information and can be used to transfer informations to the terminal users. Many people focus on the research of models, protocols and theories being used to sensor networks.This paper briefly introduces WSN and its research background, analysis the present research status of WNS at home and abroad, summarizes the key technology and the development trend of WSN. In this dissertation, the features and goals of routing protocol in WSN are well studied. And existent typical routing protocols are classified, analyzed and compared. Then, we proposed a Gradually Sleep-supported and Cone-based Topology Control Method for Wireless Sensor Networks.With the development and successfully apply of Ad Hoc networks, people already no longer contented with Ad Hoc networks only can provide the deliver the data server, but hope that Ad Hoc networks can provide more types applications(such as real-time multimedia application, network telephone etc.), that needs Ad Hoc networks provide relevant QoS guarantee.This thesis is the extensive research on how top provide routing protocols with QoS guarantee in mobile Ad Hoc networks by referring to current relevant research contributions. A multicast routing algorithm with QoS constraints has become a very important research issue in the areas of mobile networks and distributed systems. On the basis of analyzing characteristics of QoS multicast routing in Ad Hoc networks, this paper designs a multicast routing network model applied to Ad Hoc Networks with QoS constraints, and presents a QoS multicast routing algorithm based on available location by inducting the available location mechanism and the choice competition mechanism (QLMRA, A QoS Multicast Routing Algorithm Based Available Location in Ad Hoc Networks).
