Ad hoc
networks have drawn considerable attentions of researchers for the last few
years. Various applications of ad hoc networks have been reported in the
literatures including disaster management, battle field, environmental
management, healthcare, and smart grid. Ad hoc networks have some limitations namely
short operating life, unreliability, scalability, delay, high interference, and
scarce resources. In order to overcome these limitations, numerous researches
have been carried out. Smart antenna integration is one of them. It has been
shown in the literatures that smart antenna can improve network’s capacity,
increase network lifetime, reduce delay, and improve scalability by directing
antenna radiation pattern in a desired direction. But, producing a desired
antenna radiation pattern is not a simple task for resource constraint ad hoc
networks. A careful selection of beam forming algorithm is required. In this
paper we show that smart antenna system, consisting of circular microstrip
antennas and arranged in a linear arrangement, is the most suitable choice for
ad hoc network. We compare a number of smart antenna algorithms in this paper
under different noisy conditions. We show that the Least Square Constant
Modulus (LSCM) and Least Constant Modulus (LCM) algorithms outperform other
algorithms in terms of directivity and minimized side lobes.
