Abstract Multiuser access is a critical issue in distributed cognitive radio networks (DCRNs), as the collisions among the competing secondary users (SUs) may decrease the network throughput significantly. In order to reduce the collisions, we propos

Cooperative spectrum sensing (CSS) is widely investigated in cognitive radio networks (CRNs) to improve the spectrum sensing performance. To realize CSS, how to collect sensing data from the secondary users (SUs) is one of the major problems. To solv

Designing an efficient spectrum assignment (SA) mechanism is a key issue for realizing dynamic spectrum access in cognitive radio network. In multi-channel selection based SA schemes, secondary users (SUs) are able to utilize multiple channels simult

This paper proposes a roadside unit (RSU)-coordinated synchronous multi-channel medium access control (MAC) scheme for vehicular ad hoc networks (VANETs). The proposed scheme allows the on board unit (OBU) to reserve service channels (SCHs) on the co

Time reversal (TR) is one of the novel techniques on wireless power transmission (WPT), which can enhance transmission efficiency. In this paper, we use TR for WPT and propose a sequential convex programming for TR. We take the non-linear rectenna ci

Aiming at dynamic changes of network topology, high real-time security services and high network load in VANETs, this paper proposes an adaptive TDMA slot allocation strategy based on beacon messages (BMA strategy). BMA strategy makes full use of nei

Flooding broadcast is the main way of vehicular node forwarding packets in Vehicular ad-hoc network (VANET). However this way may cause network congestion especially when multiple broadcast nodes send packets to the same receiving node at the same ti
