“…In these works, CBR/UDP flows are transmitted. These studies are extended to TCP flows in [14]. But as explained in Introduction, even though a TCP flow implies two flows at the transport level, one in each direction of the multihop chain, these two flows have dependencies and asymmetric sending rates, as opposed to our work.…”

Abstract. A substitution network is a wireless solution whose purpose is to bring back connectivity or to provide additional bandwidth capacity to a network that just suffered a failure or a dramatic surge in its workload. We analyze the performance of the simplest possible multihop topology for a substitution network, i.e., the multihop chain subject to traffic transmitted in both directions. Clearly, the potential capacity of a substitution network, whose technology should be embedded in mobile routers, is very likely to be far much smaller than the prior base network. We investigate the actual performance attained by such a substitution network under various conditions of the chain length and the carrier sensing range. Our results show that the capacity, viz. its maximum attainable throughput, reaches a peak at a given workload and then, for larger values of workload, decreases towards an asymptote which value can be drastically lower than the peak value. We give insights into this performance collapse and show the need for a suitable admission control.

“…Optimization of currently-used data transmission control mechanisms: To solve the mismatch problem, many works are proposed to optimize currently-used control mechanisms at different network layers, including MAC layer optimization [4][5][6][7][8], routing layer optimization [9][10][11] and rate control layer optimization [12][13][14]. For example, at MAC layer, our earlier work [5] proposes a model-driven method to dynamically adjust the backoff window of IEEE 802.11 DCF under asymmetrical topologies of WMNs so as to improve network fairness.…”

“…The IEEE 802.11 [1] is considered as the most imperative solution for wireless Internet access [2]. It is confirmed by relatively large number of Wi-Fi hotspots in public domains and proliferation of Wi-Fi enabled cellular handsets and portable devices [3][4][5], together with the constant progress in protocol modification and optimization.…”

Network utilization by legacy transmission control protocol (TCP) is determined by its round trip time (RTT) dependent mechanism for the growth of its sending rate. The RTT does not always reflect the actual network conditions, especially in the case of wireless local area network (WLAN). Consequently, it influences the RTT-dependent mechanism falsely. This paper proposes a novel cross-layer scheme between TCP and the Institute of Electrical and Electronics Engineers (IEEE) 802.11 medium access control (MAC) that compensates for any diminished growth of TCP's sending rate because of the inclusion of non-congestion delay component in RTT, if any. The proposed scheme has two refinements. The first refinement is at the MAC layer that notifies the additional propagation delay on account of link retransmission of a TCP packet. The second refinement is at the TCP layer in which the sender adapts the sending rate by relating the aforementioned additional propagation delay to the RTT estimation. To examine the benefits, the proposed scheme is evaluated after implementing it on top of representative TCP variants; Newreno and Westwood+ (TCPW). Simulation results showed that with the proposed scheme, network utilization by native TCP is improved by more than 35% in a dedicated WLAN environment, while the performance remained protected in a shared WLAN environment.
