Design of VANET for Improvement of QoS with Different Mobility Patterns

VANETs (Vehicular ad-hoc network) are characterized by a very dynamic topology with partial infrastructure support, patterned mobility, and mobile nodes with sufficient amount of resources, intermittent connectivity and varied channel behavior. For this purpose, we always use the location information that vehicles share among them through repetitive messages that are transmitted in the VANET system. In addition to communication among the vehicles, VANET interface with communication access points provided by on road infrastructure. Thus in this paper we propose that the design of city environment VANET network with Wimax by using two key strategies which are multiple input & multiple output technology (MIMO) and adaptive modulation coding (AMC) which by combining gives the significantly enhanced data rate & maximum throughput with high efficiency in wireless network.
