However, current approaches may let TCP resumes transmission from an incorrect state when multiple link failures occur along a route at the same time, which make TCP invokes 'Fast Retransmit/ Fast Recovery' in the period immediately following TCP resuming transmission. 但当在同一条路由上同时发生多处链路中断时,现有方法在路由重建后不能从正确的状态开始恢复TCP传输,使得TCP在刚恢复传输时就启动‘快速重传/快速恢复’。
Transmits partially the communications channel which provides by China mobile with the aid of the GPRS wireless grouping exchange technology, realizes the data transparently to retransmit. 传输部分由中国移动提供的通信信道借助GPRS无线分组交换技术,实现数据透明转发。
Sliding window strategy depending on the retransmit timer is used to enhance throughput of network. 选择依赖于重发时钟的滑动窗口策略来提高网络吞吐量。
The link layer will retransmit the error frames for limited times, which can conquer the decrease of throughput caused by congestion control in TCP layer. 对于出错的无线帧,链路层能给予有限次的重传,以屏蔽TCP层对高误码率的感知;
Meanwhile it adopts the minimal number of hops to retransmit data packets from the source nodes to the actors, and guarantees the real-time request of data collection. 同时从源节点到目的反应节点采用最小跳步数机制转发报文,以保证数据收集的实时性。
ARQ must retransmit every lost packet, consuming much bandwidth. FEC would add redundant information to original data. 自动重传请求需要重传每一个数据包,消耗大量的网络带宽,而前向纠错则会增加冗余信息。

The basic idea of ARQ is when the receiver feedback a control packet after finding loss of packets, then the sender will retransmit the lost packet according to the received control packets. ARQ的基本思想是:当接收端发现丢包后反馈一个控制包给发送端,然后发送端根据接收到的控制包重传丢失的数据包。
