Abstract: There arc some drawbacks in Laycred Network Architecture, such as redundancy intra-layers and no interaclions inter-layers etc and these drawbacks have resulted in some problems-these are difficult to be solved in contemporary architecture,such as QoS,network security etc. It is when applying Layered Network Architecture to wireless network that resource-scarce and intermittent connection problems etc are included except for those mentioned above in Layered Network Architecture. The paper proposed a Component based Network Architecture in order to resolve these problems. The Component-based Network Architecture, a non-layered architecture which is composed of low coupling components, partitions the network on the basis of functions into different components and it provides high duality of service through combining these different components in an efficient way. This Network Architecture is a solution to climinate the problems encountered in Laycred Network Architecture. The paper will demonstrate the architecture thorovrghly.
