MANET中TCP拥塞控制方法综述
Survey on TCP congestion control for MANET
摘要
Abstract
Congestion control is a key issue in MANET. MANET has some special properties, such as large interference of wireless signal, heavy fading channel, multiple hops, unsymmetry links and node mobility, which may cause high packet loss rate, acknowledgement packets cumulating in intermediate nodes, lots of out-of-order packets and large jitter of round trip time. Consequently, improper congestion controls (e.g., unnecessary retransmission and mistakenly reducing the size of send window) are made and the throughput is very poor in MANET with traditional TCP congestion control mechanism. Many typical improved approaches proposed to overcome these difficulties in MANET were verified in this survey. In addition, the features and performances of these approaches were compared and concluded. According to this survey, real-time state information of the whole network obtained by cross-layer design is helpful to congestion control in MANET and this is the mainstream mechanism adopted by these proposed approaches.关键词
