Robust Cross-Layer Routing and Radio Resource Allocation in Massive Multiple Antenna and OFDMA-Based Wireless Ad-Hoc Networks

Cross-Layer Routing and Dynamic Spectrum Allocation in Cognitive Radio Ad Hoc Networks

Throughput maximization is one of the main challenges in cognitive radio ad hoc networks, where the availability of local spectrum resources may change from time to time and hop-by-hop. For this reason, a cross-layer opportunistic spectrum access and dynamic routing algorithm for cognitive radio networks is proposed, called ROSA (ROuting and Spectrum Allocation algorithm). Through local control...

Network-Layer Resource Allocation for Wireless Ad Hoc Networks

This thesis contributes toward the design of a quality-of-service (QoS) aware network layer for wireless ad hoc networks. With the lack of an infrastructure in ad hoc networks, the role of the network layer is not only to perform multihop routing between a source node and a destination node, but also to establish an end-to-end connection between communicating peers that satisfies the service le...

Cross-Layer Directional Antenna MAC and Routing Protocols for Wireless Ad Hoc Networks

In this paper we propose a Directional Antenna Medium Access (DAMA) protocol and its enhanced version called EDAMA (enhanced DAMA), which takes advantage of the benefits offered by directional antennas. Both of these schemes have been inspired by the IEEE 802.11 MAC, with major enhancements including a new neighbor discovery scheme, an optimized circular directional transmission of RTS and CTS ...
