Most of the existing media access control protocols for cognitive radio networks are based on global dedicated common control channel (GCC). They use GCC to negotiate for data channels and to protect incumbents. The GCC is prone to saturation problem, DoS attack and wasteful of bandwidth resource. Further, it may be not available in some practical cost-sensitive applications. In this paper, we present...
Most communication styles in tactical networks are one-to-many communications, which is multicast transmission. Recently, tactical networks has been evolving to Ad-Hoc-like distributed networks with OFDM-based Wideband Networking Waveform (WNW). In this paper, novel rate-adaptive multicast transmission method over OFDM-based wireless networks is proposed. Transmission rate for wireless multicast over...
As a network administrator or as a client, we need to perform the important operation over network such fixing a schedule of video conference, sending data, or doing maintenance related task regarding Quality of Service (QoS). It will be more reliable if we can get the information of the delay, performance statistics and error rate of the overall network that we belong to or we are maintaining. We...
