“…In their work, they use channel quality measurements in the handoff decisions and they employ mechanisms to control handoff frequency. An interesting approach called Cooperative Roaming (CR) is proposed in [22]. This work is very relevant to our work, while the authors introduce cooperation in order to perform layer 2 handoff, layer 3 handoff, and authentication.…”

In IEEE 802.11-based wireless networks, the stations (STAs) are associated with the available access points (APs) and communicate through them. In traditional handoff schemes, the STAs get information about the active APs in their neighborhood by scanning the available channels and listening to transmitted beacons. This paper proposes an 802.11k compliant framework for cooperative handoff where the STAs are informed about the active APs by exchanging information with neighboring STAs. Besides, the APs share useful information that can be used by the STAs in a handoff process. In this way, we minimize the delay of the scanning procedure. We evaluate the performance of our mechanisms through OPNET simulations. We demonstrate that our scheme reduces the scanning delay up to 92%. Consequently, our system is more capable in meeting the needs of QoS-sensitive applications.

Abstract-In 802.11-based wireless networks the stations (STAs) are associated with the available access points (APs) and communicate through them. In traditional handoff schemes the STAs get information about the active APs in their neighborhood by scanning the available channels and listen to transmitted beacons. This paper proposes a 802.11k compliant framework for cooperative handoff where the STAs are informed about the active APs by exchanging information with neighboring STAs. In this way we minimize the delay of the scanning procedure. We evaluate the performance of our mechanisms through simulations and we show that when our cooperative framework is applied the network performance is significantly improved. Consequently, our system is more capable in meeting the needs of QoS-sensitive applications.

“…In fact, cooperation among nodes in wireless network has been addressed to deal with those problems such as seamless handoff, beneficial for coverage, throughput, saving energy, load balancing and grid computing [6], etc. Dianati et al proposed a cooperative ARQ scheme for wireless ad-hoc networks in [7].…”

We argue that the conventional forward error correcting code (FEC) and retransmission solutions will become ineffective to transmit scalable video coding streaming in wireless mesh network (WMN) for the reason that video frame errors appear in bursts rather than random and the bad channel condition usually persists for a period in wireless channels. A novel SVC streaming cooperative transmission scheme is proposed in this paper. Our cooperative transmission scheme includes two stages among nodes in WMN. The first stage is selecting appropriate paths for the relevant SVC sub-layer streams and the second one is selecting nearby nodes to cache the network coding results of the adjacent sub-layer streams and retransmit the network coded packets to the user terminal for recovering the error packets. Simulation results are given to demonstrate the significant improvement of the SVC streaming reconstructive video quality.
