Abstract

Studies the performance improvement brought by the use of multiple antennas for each node in a multihop packet radio network (PRN). The authors propose that the antenna with the largest received power is chosen to be decoded. Four transmission strategies based on the MFR (most forward with fixed range), NFP (nearest with forward progress), MAD (minimal angular deviation), and ARR (angular deviation to transmission range ratio) routing schemes are studied. Results show that more than one antenna for each node in a PRN can improve the performance of all four transmission strategies substantially in a Rayleigh fading environment.
