Performance Improvement in Infrastructureless Networks by Using Smart Antenna Technology
Infrastructureless network is a collection of wireless nodes, which are connected in decentralized structure. Nodes in infrastructureless networks can communicate with each other and can move from one place to another. By using omnidirectional antennas, the channel in infrastructureless networks cannot be utilized 100%, so for improving channel utilization the authors proposed an adaptive MAC protocol which makes use of smart antenna technology. The proposed protocol use Global Positioning System to direct their main beam to desired direction and nulls in the direction of interferers.
