Issues and Improvements in TCP Performance over Multihop Wireless Networks
2008
2008 IEEE Sarnoff Symposium
Preserved Fulltext
TCP performance in contention-based multi-hop wireless networks is shaped by two main factors, which are unlike the wired network case. ...
Motivated by this understanding, we reformulate and enhance an existing idea for improving TCP performance by further lowering the number of control packets. ...

As a result, when RTT is 32ms, performance of the optimized iSCSI has achieved quadruple of that of the default iSCSI. ...
iSCSI has a problem of drastic performance deterioration in the case of longer-latency. Thus, we have optimized iSCSI remote storage access through multiple layers. ...
The suspend and restart of iSCSI access are controlled in the TCP layer because only TCP ACKs are received before the restart. ...

In this paper, we show that in most cases the smooth handoff by the route optimization of the Mobile IP standard cannot prevent degradation of TCP performance in events of handoffs, although it was originally ...
We also show that in utilizing the route optimization extension, the TCP performance sometimes becomes worse even than the case of the base Mobile IP, if its smooth handoff fails to avoid losses of four ...
That is the reason why the performance of TCP is further degraded when the route optimization extension is used. ...

We compare three protocols: naive flooding and two optimized flooding protocols. In naive flooding, all nodes rebroadcast received flood messages once. ...
However, contrary to common opinion, with background traffic the optimized flooding protocols perform sufficiently poorly to seriously question their viability in 802.11-based mesh networks. ...
Naive versus Optimized Flooding To understand why the performance of part-optimized flooding is different from that of optimized flooding, we need to look at the number of duplicates received. ...
