Research On Network Composing Technology Of D2D Mesh Network

IMT-Advanced system has formulated the standard and research direction for mobile communication in the future.As one of the candidate techniques,LTE-advanced system has set up a specialized research topic for Device-to-Device(D2D)communication.However,D2D technique has the shortness because of the short-distance of communication.Since the wireless mesh network(WMN)has the feature of multi-hop and self-organization,it can make up the weakness of D2D technique.So the paper will focus on the combination of D2D technique and WMN,and research on the key problem for different network structure.This paper firstly introduce the LTE and D2D technique briefly.By analyzing the shortness of D2D technique,the paper comes up with the concept of combination of D2D and WMN,which can enhance the distance of D2D communication.In regard of plane structure of D2D Mesh network,the paper focuses on the routing protocol.Classic routing protocols are introduced firstly.A new routing protocol called Capacity and Mobility-Based Routing Protocol is proposed.The protocol comes up with a new method to measure the router and creatively uses the power to measure the router weight.Secondly,by means of the combination of D2D and WSN,D2D users can be divided into clusters to broadcast data resources.The paper studies on the clustering algorithm.A new algorithm is proposed to solve the clustering problem.The algorithm uses a combination of distributed and centralized manner,taking advantage of high computing ability and the discovery ability of UEs.
