Adaptive Network Coding Scheme for TCP over Wireless Sensor Networks

摘要: The purpose of this paper is to develop a network coding scheme enhance TCP performance in wireless sensor networks. It well known that performs poorly over links which suffer from packet losses mainly due the bad channel. To address problem, it useful incorporate into TCP, as can offer significant benefits terms throughput, reliability, and robustness. However, encoding decoding operations techniques will bring an additional delay has negative effect on applications In paper, we propose adaptive (ANC) contains two major aspects: adjustment redundancy factor R window size CW. We dynamically adjust these parameters depending measured loss rate, so proposed ANC effectively mask reduce coding. our evaluated by simulations using NS-2 simulator. Compared other schemes, not only achieves good throughput but also lowest average maximum all experimental environments.
