“…In mesh networks, nodes in a neighborhood connect wirelessly to form a grid and share Internet access from one or a few nodes. Many of these studies focus on sharing a single connection between multiple devices, especially when this connection is temporarily idle, such as DOMS [ 16 ] and FatVAP [ 17 ]. DOMS constructs a number of “virtual” access points (APs), one for each of the surrounding Wi-Fi devices.…”

“…PCI measures the continuity of video playback in an end device [ 16 ] and is defined as PCI = 1 – pause time/playout time , where pause time is the total pause duration experienced by the viewer and playout time is the total duration of successful video playback. A higher PCI value indicates better video quality and user perception.…”

Avoiding Biased-Feeding in the Scheduling of Collaborative Multipath TCP

Smartphones have become the major communication and portable computing devices that access the Internet through Wi-Fi or mobile networks. Unfortunately, users without a mobile data subscription can only access the Internet at limited locations, such as hotspots. In this paper, we propose a collaborative bandwidth sharing protocol (CBSP) built on top of MultiPath TCP (MPTCP). CBSP enables users to buy bandwidth on demand from neighbors (called Helpers) and uses virtual interfaces to bind the subflows of MPTCP to avoid modifying the implementation of MPTCP. However, although MPTCP provides the required multi-homing functionality for bandwidth sharing, the current packet scheduling in collaborative MPTCP (e.g., Co-MPTCP) leads to the so-called biased-feeding problem. In this problem, the fastest link might always be selected to send packets whenever it has available cwnd, which results in other links not being fully utilized. In this work, we set out to design an algorithm, called Scheduled Window-based Transmission Control (SWTC), to improve the performance of packet scheduling in MPTCP, and we perform extensive simulations to evaluate its performance.

“…Generally, the existing QoS protocols achieve service differentiation by assigning different classes of traffic with different contention related parameters. For instance, enhanced distributed coordination function (EDCF) of IEEE 802.Ile protocol [5] provides 4 access categories (AC) and 8 priorities, which are supported by assigning different contention window sizes and interframe spaces. However, the delay of high-priority packets is not bounded under heavy load in multi-hop networks, because high-priority packets may be blocked by alternate transmissions of low-priority packets within 2-hop range, and unbounded delay for initiating an RTS/CTS dialogue cannot guarantee the delay of all the real-time packets.…”

A QoS-based multiple access (QMA) protocol for multi-hop ad hoc networks is proposed. In this paper, the traffic is divided into real-time and non real-time traffic. According to the protocol, nodes with real-time traffic have higher priority to access channel than those with non real-time traffic by broadcasting forecast bursts (FB) in earlier contention slots. Meanwhile, traffic is scheduled according to its delay and the earliest deadline first (EDF) principle. Through simulations, it is shown that the QMA protocol outperforms Carrier Sensing Multiple Access with Collision Avoidance (CSMA/CA) protocol, and it can provide QoS guarantees in multi-hop networks.

Based on the concept of random contention and collision resolution, a QoS-based multiple access (QMA) protocol for ad hoc networks is proposed to support multimedia service and multi-hop architecture. The traffic is divided into two groups with different requirements on delay, namely real-time traffic and data (or best effort) traffic. According to the protocol, nodes contend to access channel, and the node broadcasting the most forecast bursts (FBs) get right to access the channel according to its packet delay and the earliest deadline first (EDF) principle. Meanwhile, the nodes with real-time traffic have higher priority to access channel than those with data traffic by broadcasting FBs in earlier contention slots. Through simulations in OPNET modeler, it is shown that the QMA protocol outperforms the IEEE 802.11e protocol in terms of throughput, message discard rate and average packet delay, and the QMA protocol can provide differentiated QoS guarantees for traffic in multi-hop networks.
