The Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) is an integrated algorithm employed in the Enhanced Distributed Channel Access (EDCA) in the IEEE 802.11p protocol. CSMA/CA manages the access of packets to the medium and its main role is to avoid collisions among them. An essential process of CSMA/CA is the backoff period in which the packets has to wait for a random number of...
Vehicular-to-Vehicular (V2V) and Vehicular-to-Infrastructure (V2I) communications in Vehicular Ad hoc Network (VANET) environment rely mainly on Medium Access Control (MAC) to minimize the delay and maintain reliable access to the communication medium. IEEE 802.11p standard is developed to achieve these goals. However its performance deteriorates drastically in large networks due to the high level...
Using wireless sensor networks (WSNs) in delay and reliability critical environments is highly desired due to their unique advantages such as low cost, ease of deployment, and redundancy. However, successful deployment of resource-limited WSNs in such applications requires strict quality-of-service (QoS) provisioning techniques to meet the desired latency and reliability targets of those applications...
This article studies the problem of message dissemination in Cognitive Radio Ad Hoc (CRAHNs) over TV white bands. By exploiting the supreme propagation characteristics of low-frequency channels, this article proposes two message dissemination protocols that use acknowledged transmissions to guarantee dissemination reliability. These two protocols rely on assistance from neighboring terminals to expedite...
Plug-in Electric Vehicles (PEVs) are expected to be widely utilized in the near future if issues related to the availability of charging infrastructure are resolved and if PEVs are efficiently integrated with the smart grid. The Vehicle-to-Grid (V2G) system is an emerging technology that enables the communication and control between PEVs and the smart grid. This promising concept is designed to provide...
