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

Adaptive Cross-Layer Distributed Energy-Efficient Resource Allocation Algorithms for Wireless Data Networks

The issue of adaptive and distributed cross-layer resource allocation for energy efficiency in uplink code-division multiple-access (CDMA) wireless data networks is addressed. The resource allocation problems ...

Exploiting Transmit Buffer Information at the Receiver in Block-Fading Channels

It is well known that channel state information at the transmitter (CSIT) leads to higher throughput in fading channels. We motivate the use of transmit buffer information at receiver (TBIR). The thesis of thi...

Channel MAC Protocol for Opportunistic Communication in Ad Hoc Wireless Networks

Despite significant research effort, the performance of distributed medium access control methods has failed to meet theoretical expectations. This paper proposes a protocol named "Channel MAC" performing a fu...

Throughput-Optimal Scheduling with Low Average Delay for Cellular Broadcast Systems

While a number of scheduling policies achieve the maximum throughput region, the average delay minimization problem for cellular broadcast systems still awaits its complete solution. To this end, we introduce ...

A Coordinated Resource Allocation Algorithm for Infrastructure-Based Relay Networks

A resource allocation algorithm for orthogonal frequency division multiple access-based and infrastructure-based relay networks is introduced in this paper. The algorithm is applied in the downlink of a single...

Enhancing the Performance of Random Access Networks with Random Packet CDMA and Joint Detection

Random packet CDMA (RP-CDMA) is a recently proposed random transmission scheme which has been designed from the beginning as a cross-layer method to overcome the restrictive nature of the Aloha protocol. Herei...

Cross Layer PHY-MAC Protocol for Wireless Static and Mobile Ad Hoc Networks

Multihop mobile wireless networks have drawn a lot of attention in recent years thanks to their wide applicability in civil and military environments. Since the existing IEEE 802.11 distributed coordination fu...

Medium Access in Spread-Spectrum Ad Hoc Networks with Multiuser Detection

Conventional medium access control protocols are designed to avoid simultaneous transmissions, based on a simple collision model in the underlying physical layer. Recently, strong physical layer capabilities, ...

Practical Radio Link Resource Allocation for Fair QoS-Provision on OFDMA Downlink with Partial Channel-State Information

We address the problem of resource allocation on the downlink of an OFDMA single-cell system under fairness constraints with limited channel state information (CSI). Target QoS corresponds to a minimum user da...

Further Development of Synchronous Array Method for Ad Hoc Wireless Networks

A further development of the synchronous array method (SAM) as a medium access control scheme for large-scale ad hoc wireless networks is presented. Under SAM, all transmissions of data packets between adjacen...

Nonconcave Utility Maximisation in the MIMO Broadcast Channel

The problem of determining an optimal parameter setup at the physical layer in a multiuser, multiantenna downlink is considered. An aggregate utility, which is assumed to depend on the users' rates, is used as...
