Abstract :
Generally, a node have omnidirectional antenna
in wireless network. While a node is communicating, the
vicinity nodeshave tosilent even they have packet to send.
Thus, we can’t get better spatial reuse because of the Omni
direction antenna. Because of collision in the network with
more nodes reduces the performance. But, since last decade
the researcher got more attention with directional antenna
than omnidirectional antenna because of its spatial reuse
and higher range of packet transmission. But, the hidden
and deaf node problem is severe as well. We proposed a
system that takes benefits of directional antennas like
spatial reuse, higher transmission range. Moreover, our
scheme combat against deaf and hidden node problem.
Using our scheme we derived saturation network
throughput and delay. In order to validate we use OPNET
simulation tool. The analytical and simulation results
illustrations that the performance of the network is
enhanced.
