Description: WiMAX is called worldwide interoperability for microwave access. This is one of the methods of wireless communication standard named under IEEE 802.16 standard. In this technique, simulation of the WiMAX system is performed under different channel conditions. The same system is simulated in two different scenarios. In the first scenario, the system is made work under LDPC encoding and LDPC decoding method of channel coding. In the second scenario, the system is made to work under OSTBC encoder and OSTBC combiner (encoder) of MIMO. The performance of the system is s studied and compared under LDPC and MIMO encoder and decoder techniques. -WiMAX is called worldwide interoperability for microwave access.

Description: Anypath routing is proposed to improve the performance
of wireless networks by exploiting the spatial diversity and
broadcast nature of the wireless medium. In this paper, we study
anypath routing in wireless networks with directional antennas,
and propose DART (Directional Anypath RouTing), a crosslayer
design of MAC and routing layers. For the routing layer,
we propose two shortest directional anypath routing algorithms
based on two antenna models. Our routing algorithms are
simple and fast, thus are suitable for implementation in practical
protocols. For the MAC layer, we present a directional anycast
MAC, which is an enhancement to the IEEE 802.11 MAC, making
DART suitable for integration into current systems. Simulation
results show that DART can significantly reduce the packet
transmission delay.
