Spatial multiplexing gains for realistic sized ad hoc networks with directional antenna arrays.(Research Article)

EURASIP Journal on Wireless Communications and Networking | January 1, 2007| | Copyright

We concentrate on an ad hoc network model with nodes on integer lattice points over a 2D plane. We examine the limits of ad hoc network performance for systems with antenna arrays capable of allowing both spatial multiplexing and directional processing. Two cases are considered. In the first case, we consider "perfect" directional antenna arrays, in other words, each node can form beams of infinitesimally narrow beamwidth. In this case, the throughput capacity of an ad hoc network is independent of the network size. In the second case, we consider a more practical system ...
