Dual Polarised Directional Communication Based Medium Access Control Protocol for Performance Enhancement of MANETs

Due to increasing popularity of Mobile Ad hoc Networks (MANETs), research in this area has constantly strived to improve performance of these networks. In this paper Dual Polarized Directional Antenna based Medium Access Control (DPDA-MAC) protocol is presented to enhance the throughput of MANETs. Nodes operating in accordance with DPDA-MAC are capable of simultaneously using orthogonal (vertical and horizontal) polarisations of directional antenna for communication. DPDA-MAC is designed to support directional medium access over orthogonal polarisations (vertical and horizontal). Through extensive simulations it is proved that DPDA-MAC mitigates interference, exposed node problem and deafness, thus enhancing throughput of MANETs.
