Summary Bandwidth estimation in mobile ad hoc networks (MANET), where each node can move randomly and is capable of frequently changing its link with other nodes, is a challenging task. Motivation of this work is in contrast with TCP new‐reno which decreases the congestion window both in the event of link failure and congestion, which in the case of packet loss due to link failure should be close to available channel bandwidth. The proposed novel approach capture the node's mobility behavior in broadcast and unicast scenarios of IEEE 802.11 standard to efficiently estimate the sender's window size. This proposal introduces a data structure and source‐to‐destination path stability metric to imitate the mobility behavior of network and presents the analytic characterization of steady‐state throughput as a function of packet loss, round trip time, and path stability over IEEE 802.11 infrastructure‐less MANET. The performance is evaluated over random‐walk, random‐waypoint, and Gauss‐Markov mobility models in 2D and 3D environments using QualNet 7.4 network simulator. The proposed analytical model is also evaluated through two‐tailed statistical test. Analytical, statistical, and simulation‐based comparisons demonstrate the effectiveness of proposed method in high‐mobility scenarios.

“…Probe [12], WBest [13], TSProbe [14], and IdleGap [7] are some examples of link estimation mechanisms for wireless networks. While WBest calculates both capacity and available bandwidth, AdHoc Probe provides only the path capacity of the wireless channel.…”

“…In this section we analyse the main principles and results of rt-Winf, since it will be the basis of the new approaches for XCP-Winf and RCP-Winf. IdleGap [7] was the underlying basis for the development of rt-Winf. The main purpose of rt-Winf was to mitigate IdleGap main issues, being compatible with all systems and evaluating both the link capacity and the available bandwidth without overloading the network.…”

“…Being able to accurately monitor link capacity and available bandwidth and then use that information to perform accurate congestion control is a main challenge in wireless communications. In [6] we proposed the rt-Winf algorithm, which is a new wireless inference mechanism, based on IdleGap [7], that is able to estimate available bandwidth and path capacity. rt-Winf uses the information included in RTS/CTS packets to measure the transmission time and obtain the link capacity and available bandwidth.…”

Congestion control in wireless networks is strongly dependent on the dynamics and instability of wireless links. Therefore, it is very difficult to accurately evaluate the characteristics of the wireless links. It is known that TCP experiences serious performance degradation problems in wireless networks. Moreover, congestion control mechanisms that rely on network interaction and network parameters, such as XCP and RCP, do not evaluate accurately the capacity and available link bandwidth in wireless networks. In this paper we propose new explicit flow control protocols for wireless mesh networks, based on XCP and RCP. We name these protocols XCP-Winf and RCP-Winf. They rely on the MAC layer information gathered by a new method to accurately estimate the available bandwidth and the path capacity over a wireless network path. The estimation is performed in real time and without the need to intrusively inject packets in the network. These new congestion control mechanisms are evaluated in different scenarios in wireless mesh and ad hoc networks and compared against several new approaches for wireless congestion control. It is shown that both XCP-Winf and RCP-Winf outperform the evaluated approaches, showing its stable behavior and better channel utilization.

With rapid progresses in computing technologies, the integrated and ubiquitous computing environment has been developed into Telematics services, which focus on the safety, amusement and information of vehicles. However, high mobility is an essential characteristic in vehicular communication systems, and also the primary cause of challenges. Existing solutions for wireless communication become ineffective or even infeasible in such highly dynamic network topologies. With considering the regular moving patterns of public transportation systems such as buses, trains and shuttles, this paper proposes a novel channel capacity estimation and queue management scheme for VANET. It takes geographic and time considerations into account and develops an efficient channel capacity estimation scheme. Based on the proposed channel capacity estimation scheme, the proposed scheme can well manage the queues at both RSU and vehicle mobile router (VMR). The simulation results are promising and optimistic and can validate the contributions of the proposed scheme.
