摘要：Mobile Ad hoc Networks (MANETs) have drawn considerable attentions of the researchers for the last fewyears. MANETs, consisting of mobile nodes, are self-organizing and self-configuring and hence can bedeployed without any infrastructure support. MANETs also have some limitations including short-life,unreliability, scalability, latency, high interference, and limited resources. In order to overcome theselimitations many innovations and researches have been done in this field. Incorporating smart antennasystem with the mobile nodes is one of them. It has been shown in the literatures that smart antenna canimprove network capacity, increase network lifetime, reduce delay, and improve scalability by usingdirectional radiation pattern. But, there are some unsolved issues too. Smart antenna requires a largenumber of antenna elements that a resource constraint mobile node can hardly handle. Hence, one majordesign issue is to achieve a desired radiation pattern by using minimum number of antenna elements.Another important issue is the arrangement of antenna elements. Antenna elements can be arranged inlinear, planar, and circular manners. In this paper we have addressed these issues. We have proposed awindow based smart antenna design for MANETs. Our target is to improve the routing performance ofMANETs. We have shown that by using appropriate window function a desired radiation pattern can beachieved with a minimum number of antenna elements.
