A Bidirectional Polling MAC Mechanism for IoT

A distributed polling service-based MAC protocol testbed

Medium access control (MAC) protocols play a vital role in wireless networking. It is well-known that the high control overhead of IEEE 802.11 MAC is the limiting factor on the throughput and delay performance of wireless networks. In our prior work, three polling service-based MAC protocols (PSMACs) are developed to amortize the high control overhead over multiple frame transmissions, thus ach...

Harvested Energy-adaptive Mac Protocol for Energy Harvesting Iot Networks

In energy harvesting IoT networks, an energy queue state of an IoT device will change dynamically and the number of IoT devices that transmit data to the IoT AP will vary in a frame. So we need a MAC protocol to adjust the frame length taking the amount of energy of IoT devices into consideration. Since the existing Framed slotted ALOHA (F-ALOHA) Medium Access Control (MAC) protocol utilizes th...

A Bandwidth Guaranteed Polling MAC Protocol for Ethernet Passive Optical Networks

While the backbone networks have experienced substantial changes in the last decade; the access networks have not changed much. Recently, passive optical networks (PONs) seem to be ready for commercial deployment in access networks due to the maturity of a number of enabling technologies. long distance and reduced maintenance. Among PON technologies, the Ethernet PON (EPON) presently being stan...

A Priority-based Parallel Schedule Polling MAC for Wireless Sensor Networks

—MAC (medium access control) protocol plays an important role in Wireless Sensor Networks (WSNs) due to limited bandwidth and battery. MAC protocol that provides Priority-based quality of service (QoS) which satisfies various traffic transmission requirement will form the base of highperformance network application. This paper presents a new priority-based parallel schedule polling MAC protoco...
