基于组播通信的交通通信网络研究

研究交通通信网络,提高网络的吞吐量和数据传输效率。针对传统的单播组网中通信发送者需要多次复制相同的数据包以满足多个接受者同时提出的数据请求,随着数据请求的增多使得发送者的通信负担加重,造成网络拥塞、吞吐量不高的问题。为了解决上述难题,提出基于组播通信的交通通信网络的组网方法。采用Mesh结构构建交通通信网络的组播模型,使得网络节点之间建立有线或无线的连接,然后利用网络编码算法实现网络间的通信,使得源点只需发送一次就可向多个终点成功传输相同的数据。实验表明,组网方法能够有效解决数据请求过多时网络吞吐量不高的问题,同时提高了数据传输的效率,取得了满意的结果。

Traffic Communication Network Research Based on Multicast Communication

Research the traffic communication network to increase network throughput and data transmission efficiency.In traditional unicast network of communication,sender has to duplicate the packet many times to satisfy the data request by multi-recipients.With the increasing of the data request,the sender’s communication burden increases,causing the congestion and low throughput.In order to solve the problem,we presented a traffic communication network model based on multicast communication.The Mesh structure was used for building the multicast traffic communication network model to enable the wired or wireless connection between network nodes,By the network coding algorithm was used to realize network communications,which enables the source point to send packet only once to the multiple end nodes.Experimental results show that this method can effectively improve the efficiency of data transmission.
