Scalability of Ad Hoc Dynamic Spectrum Access Networks

Abstract :-

Dynamic Spectrum Access allows wireless users to access a wide range of spectrum which increases a node’s ability to communicate with its neighbors, and spectral efficiency through opportunistic access to licensed bands. Our study focuses on the scalability of network performance, which we define in terms of network transport capacity and end-to-end throughput per node, as the network density increases.

Performance Analysis of Wireless Local Area Networks

Abstract :-
In an infrastructure based wireless network, access point (AP) is the central authority which controls all the registered nodes and relaying traffic in the network. Even though all traffic is routed through AP, the open nature of the underlying medium is prone to environmental factors, etc. which degrade the performance of the overall network. However, in a saturated case the AP becomes the bone of contention among nodes which can result in collisions, packet drops, etc. In this study, authors analyze the performance of 802.11 WLANs that utilizes the Distributed Coordination Function (DCF).
