In this section, we introduce problems that arise as a result of directional communication.
We consider two such problems and propose techniques that consequently lead to throughput, delay and scalability enhancement.
Studies have shown cross layer to be very effective in enhancing Qo S performance under spectrum scarcity and other constraints.
In this dissertation, our main goal is to enhance performance (e.g., throughput, delay, scalability, fairness) by developing novel cross layer techniques in single-hop single-channel general ad hoc networks.
Simulation results confirm improved performance compared to existing relay based protocols.
In the third section, we make use of directional antenna technology to enhance spatial reuse and thus increase network throughput and scalability in ad hoc networks.
Indeed, an architecture that can be deployed to monitor the habits of birds in their natural habitat, and which, in other circumstances, can be organized to interconnect rescue crews after a Tsunami disaster, or yet can be structured to launch deadly attacks onto unsuspecting enemies.

In this context, we identify various functional blocks, and show through simulations that global and local perturbations through parametric correlation can be used for performance optimization.
In the second section, we propose MAC (Medium Access Control) scheduling approaches for omni-directional antenna environment to enhance throughput, delay, scalability and fairness performance under channel fading conditions.
