Cross-Layer Design for the Physical, MAC, and Link Layer in Wireless Systems

A method to increasing the Quality of Service (QoS) in Wireless body area networks by providing a MAC layer Protocol based of Internet of Things

With the development of technology, the use of wireless telecommunication networks for the various affairs is essential. These networks are one of the safest and most widely used networks, for instance, in medical care and remote patient monitoring. What matters is the quality of service in these networks. The purpose of this paper is to increase packet transduction in a wireless body area netw...

Multi-channel Medium Access Control Protocols for Wireless Sensor Networks: A Survey

Extensive researches on Wireless Sensor Networks (WSNs) have been performed and many techniques have been developed for the data link (MAC) layer. Most of them assume single-channel MAC protocols. In the usual dense deployment of the sensor networks, single-channel MAC protocols may be deficient because of radio collisions and limited bandwidth. Hence, using multiple channels can significantly ...

Lifetime Maximization by Cross-Layer Design considering Power Control, MAC, Routing in Sensor Networks

We consider the cross-layer design considering physical layer, MAC layer, and network layer to maximize the lifetime of energy-constrained wireless sensor network. Our solution is based on system model that considers reliability as well as physical layer (i.e., power control), data link layer (i.e., link scheduling) and network layer (i.e., routing protocol) jointly. To obtain more energy-effic...

Congestion-aware cross-layer design for wireless ad hoc networks

Ad hoc networks have emerged recently as an important trend of future wireless systems. The evolving wireless networks are seriously challenging the traditional OSI layered design. In order to provide high capacity wireless access and support new multimedia network, the various OSI layers and network functions should be considered together while designing the network. In this thesis, we briefly...
