  • asymmetric Hidden Node Problem aware routing metric for wireless mesh networks
    Consumer Communications and Networking Conference, 2019
    Co-Authors: Keisuke Maesako, Yumi Takaki, Tomio Kamada, Chikara Ohta
    Abstract:

    In recent years, wireless mesh networks (WMNs) have become popular because of their wide coverage areas and high fault tolerance. Although unlicensed-band off-the-shelf wireless devices based on IEEE 802.11 are widely deployed, WMNs based on IEEE 802.11 suffer from degradation of throughput owing to the Hidden Node Problem. To mitigate this Problem, in this study, we developed a new routing metric called the “Asymmetric Hidden Node Problem Aware routing Metric (AHAM).” AHAM enables a new flow to establish a source-destination path that largely avoids not only interference with Hidden Nodes of existing flows but also making Hidden Nodes on that path interfere with existing flows. This is because the Hidden Node Problem can asymmetrically impact throughput between flows when new flows are established. As a response, AHAM aims to estimate the influence of Hidden Nodes accurately and compensate for how both the new and existing flows influence each other. Simulation results showed that AHAM realizes high throughput while maintaining network fairness compared with other metrics.

  • fighting against access collision and Hidden Node Problem in broadcast scheme of wireless ad hoc networks
    Global Communications Conference, 2013
    Co-Authors: Xianbo Chen, Lihfeng Tsaur, Hazem H Refai
    Abstract:

    Broadcast service is an integral part of wireless networks, through which important control and signaling information are typically exchanged. However, its multi-receiver nature determines that broadcast suffers more from access collision and Hidden Node Problem. In wireless ad hoc networks, the phenomenon becomes even worse due to the absence of a central coordinator. Existing media access control (MAC) protocols in wireless ad hoc networks were primarily designed for unicast service and the potential broadcast support is not satisfying. In this paper, we introduce a MAC layer protocol, namely Parallel Signaling and Persistently Synchronous MAC (PS2MAC) that can significantly alleviate both access collision and Hidden Node Problem. A novel relay technique is deployed in PS2MAC so that a superior broadcast performance, such as throughput and packet delivery ratio, is achieved. The conclusion is supported with simulation analysis.
