In Vehicular ad-hoc networks (VANETs), resource allocation has become one of the primary tasks. Thus, a system should be well-designed so that information could be transmitted reliably and efficiently. As vehicular communication has several character

In this paper, we propose a medium access control (MAC) protocol to allow a radio over fiber-based wireless local area network (RoF-based WLAN) to coexist with legacy carrier sense multiple access with collision avoidance (CSMA/CA)-based WLANs. In Ro

The demand for wireless local area networks (WLANs) has drastically increased due to the prevalence of mobile devices, such as smartphones and tablet personal computers. In such an environment, a large number of basic service sets (BSSs) can overlap

In IEEE 802.15.3 wireless personal area networks, the acknowledgement (ACK) mechanism has significant impact on the overall throughput. In this paper, we propose a channel adaptive ACK (CA-ACK) mechanism where an ACK is selectively transmitted depend

IEEE 802.11n standard has introduced the new schemes in MAC and HT-PHY layers to improve network throughput. The new schemes in MAC layer are A-MSDU, A-MPDU and Block ACK. In the HT-PHY layer there are MIMO transmission using up to 4 spatial streams,
