TCP Friendly Rate Adaptation for Multimedia Streaming in Mobile ad hoc Networks
Simulations show that the performance of ADTFRC is higher than standard TFRC and TCP with explicit-link-failure-notification (ELFN) support in terms of throughput, rate adaptation behavior and application level quality while still maintaining the TCP-Friendliness property.
On TCP Performance in Multihop Wireless Networks
This paper studies TCP performance over static, ad hoc networks that use IEEE 802.11 protocol as the access method, and proposes two techniques of link RED and adaptive spacing at the link layer that can improve TCP throughput by 5% to 30%.
