In fact, on the one hand, FEC introduces redundancy for error correction purposes and this redundancy utilizes scarce and costly wireless resources. On the other hand, ....

....utilizes scarce and costly wireless resources. On the other hand, increasing transmission power to decrease the bit error rate results in higher energy consumption and thus in shorter battery life. The effects of FEC and power management on TCP performance have been studied separately in [6] and [20] Little effort has been devoted so far to considering the effects of both FEC and power management at the same time. In this paper we study the joint effects of FEC and power management on TCP performance and how they can be utilized for performance optimization purposes. To this end, ....

.... its performance, either by tuning existing features [7] 8] or by introducing extensions, such as explicit congestion notifications [10] Considerable attention has also been devoted to FEC coding that is able to adapt to higher layer protocol requirements, and to TCP in particular (e.g. 11] [12], 13] None of these works, however, suggested improvements of the sliding window mechanism itself. In fact, to the best of our knowledge, the idea of basing the number of retransmissions (or the FEC coding redundancy) on the position of the packet within a window, which is central to this ....

....improves the end to end performance at the expense of local buffering of packets to retransmit in case of loss and increased complexity. Methods have been postulated for a number of different techniques operating at different levels. For example, link level forward error correction (FEC) [4] operates below TCP. Some methods, such as explicit loss notification (ELN) 5] which make the TCP stack aware of packet losses due to link errors, need some sort of coupling between TCP and the link level, and require TCP This work is supported by the Ministero dell Istruzione, Universit e ....

Other methods proposed involve changing the TCP stack at the end points, for example TCP Peach [6] The idea introduced in this paper is orthogonal to all these techniques (apart from link level FEC [4], a similar but less general concept) It operates at the physical or link level, by trading the bandwidth of the wireless hop for packet loss rate. It does not interfere in any way with the normal behaviour of the TCP stack, but simply entails the wireless link parameters being appropriately ....
