Special Issue Information

Dear Colleagues,

This special issue will focus on the design of wireless ad hoc and sensor networks with directional antennas. The antennas could have single-beam or multi-beam transmission capabilities. They could be switched  or adaptive antennas. Directional wireless networks bring many benefits such as higher throughput, longer communication range, spatial reuse due to separate communication coverage, interference reduction from neighbors, etc.

This special issue emphasizes the new network architecture, algorithms, and protocols to explore the benefits of directional antennas in multi-hop wireless communications. We would especially encourage research papers in the following topics (other relevant topics are also welcome):

Category 1: New Network Architecture and Applications

  • Wireless topology control under directional communications;
  • Power control schemes during wireless transmissions;
  • Wireless mesh network architecture under multi-beam antennas;
  • Neighboring discovery schemes;
  • Exciting applications with directional communications;
  • MIMO-oriented communication architecture; etc.

Category 2: New Network Algorithms

  • Enhanced congestion control algorithms under directional communication loss;
  • Channel allocation algorithms under multi-channel or dynamic spectrum access;
  • QoS-based Scheduling in either MAC layer or Routing layer;
  • MIMO-oriented communication optimization;
  • Directional Graph theory for connectivity and coverage;
  • Capacity models under directional, asymmetric links; etc.

Category 3: New Network Protocols

  • Directional MAC;
  • Routing under antenna deafness;
  • Capture-aware protocols;
  • Cross-layer design protocols;
  • Higher layer design (Transport layer, Application Layer, etc.);
  • Physical characteristics aware communications (such as considering the antenna beam characteristics, MIMO weight vector change, etc.); and so on.

In contrast to most wake-up radios (WuR) to date, which are short range, ours is applicable to long-range deployments.

This paper describes a long-range directional wake-up radio (LDWuR) for wireless mobile networks. In contrast to most wake-up radios (WuR) to date, which are short range, ours is applicable to long-range deployments. Existing studies achieve long distance by using modulation and coding schemes or by directional antennas, though the latter require exploring the direction of the transmitter. To address this issue, our LDWuR adopts both static and dynamic antennas, where the static ones are directional, while the dynamic ones are omnidirectional for beamforming. We present our LDWuR prototype and design principle. Simulation results show that our LDWuR and event-driven MAC protocol suppress the idle-listening of Wi-Fi stations in a wireless network, thereby enhancing the Wi-Fi power savings. Full article

This survey paper presents the state-of-the-art directional medium access control (MAC) protocols in wireless ad hoc and sensor networks (WAHSNs). The key benefits of directional antennas over omni-directional antennas are longer communication range, less multipath interference, more spatial reuse, more secure communications, higher throughput and reduced latency. However, directional antennas lead to single-/multi-channel directional hidden/exposed terminals, deafness and neighborhood, head-of-line blocking, and MAC-layer capture which need to be overcome. Addressing these problems and benefits for directional antennas to MAC protocols leads to many classes of directional MAC protocols in WAHSNs. These classes of directional MAC protocols presented in this survey paper include single-channel, multi-channel, cooperative and cognitive directional MACs. Single-channel directional MAC protocols can be classified as contention-based or non-contention-based or hybrid-based, while multi-channel directional MAC protocols commonly use a common control channel for control packets/tones and one or more data channels for directional data transmissions. Cooperative directional MAC protocols improve throughput in WAHSNs via directional multi-rate/single-relay/multiple-relay/two frequency channels/polarization, while cognitive directional MAC protocols leverage on conventional directional MAC protocols with new twists to address dynamic spectrum access. All of these directional MAC protocols are the pillars for the design of future directional MAC protocols in WAHSNs. Full article
