N2 - The aggregate throughput of a wireless ad hoc network depends on the hidden nodes problem and the usage of same polarized omnidirectional antenna on every node. Hidden node problem can be avoided by using optimal physical carrier sensing range in the wireless ad hoc network to achieve the good aggregate throughput. Moreover, using different polarization might further increase aggregate throughput because of the possible concurrent transmissions in overlapped physical carrier sensing range for different transmitting nodes to different receiving nodes. In this paper, optimal physical carrier sensing range is calculated based on the signal to interference and noise ratio and distance between transmitter and receiver nodes in the ad hoc network to avoid the packet collision in ongoing receiver node. After that, the adaptive usage of polarized antenna will be applied to further increase the aggregate throughput in ad hoc network. The simulation results show that the proposed methods can give the higher aggregate throughput for ad hoc network.
