A Novel Network Coding Algorithm to Improve TCP in Wireless Networks - 2020

A Novel Network Coding Algorithm to Improve TCP in Wireless Networks

Research Area:  Wireless Sensor Networks


This paper proposed a novel algorithm called Efficiency Network Coding (ENC) for wireless mesh networks. The ENC algorithm is based on COPE protocol and consists of two parts: In the first part, ENC codes the packets which have a smaller difference in size than other packets and so uses less bandwidth to code and send packets. In the second part, the nodes which their packets are in front of virtual queue and the ones which their packets are in front of output queue participate in coding. Therefore, ENC increases coding opportunities and takes less time for sending packets. The proposed ENC is implemented in NS2.34 with TCP-New Reno on COPE framework and compared with the throughput of TCP in COPE. The results of this paper show that the throughput of the proposed ENC is greater than that of COPE in most cases. The time complexity of ENC depends on the overhear packets in the nodes and can be less, equal, or more than COPE in different conditions.
