The Impacts of Physical Layer Parameters on the Connectivity of Ad-Hoc Networks
Source: University of California
The authors study the effects of physical layer parameters on the connectivity of fading wireless ad-hoc networks. Relying on a symbol error rate connectivity metric for wireless ad-hoc networks, they assume a pair of nodes are connected if their bidirectional measure of connectivity satisfies a given threshold. They investigate the effects of three parameters on the connectivity phenomenon. First and assuming the nodes are distributed over a fixed finite area, they study the effects of the changes in nodes density on connectivity. Next, they measure the connectivity effects of the interference coefficients, i.e., the portion of power an interfering node contributes to other links. Finally, they experiment with threshold of link quality for connectedness.
