In order to accelerate the information sharing, all-to-all broadcast needs more users to take part in the packet transmission at the same time. Directional antennas, which are capable of forming multiple beams, can provide improved spacial reuse on one hand. On the other hand, through analyzing the contention scenarios listed for multi-hop wireless networks in previous works, we find that the contention...
Networking Radar-Communication Integrated System (RCIS) promises an improved performance of radar and communication system platform by expanding scanning range and sharing information with each other. But equipping RCIS with directional antennas, in return, will worsen network's connectivity. In this paper, we aim to address the problem of neighbor discovery stage in networking process. Then, we are...
In order to share information among all nodes, an all-to-all-broadcast scheme is needed for situation awareness networks. For this type of distributed sensor network, a directional antenna array, called multi-beam adaptive array (MBAA) is proposed to improve the transmission range and reject the interference. In this paper, an all-to-all-broadcast oriented MAC protocol is designed based on receiver-oriented...
The paper first gives a general review about the studies on the wireless communication of the cable tunnels, then analyzes the technical requirements of signal coverage in the electric power tunnel, and finally puts forward a new way of wireless intercom communication in the tunnel. In this way, several transmitters in the electric power tunnels simultaneously send the same signal over the same frequency...
