Joint Transmit and Receive Antenna Selection Scheme for MIMO Vehicular Adhoc Networks

Abstract

Beam forming, spatial diversity and spatial multiplexing; the underlying principles of MIMO have made their way in adhoc networks in achieving increased communication range, increased reliability and throughput. This led to more focused work on trade-off between MIMO benefits on one side and complexity, cost on the other, caused by addition of more antennas and other circuitry. MIMO can fully reap its benefits in V ANET without any constraints on adding more antennas on pre-text of small terminal size and increased energy consumption, which is the case with other constrained environments. The only impediment can be enhanced requirement of RF components leading to proportionate increase in complexity and cost. In this paper we have proposed and simulated joint transmit and receive antenna selection scheme to get the MIMO benefits to maximum possible extent in V ANETs, which will result in low cost and less complex alternate with minimal hardware requirements. The performance of proposed scheme has been analyzed in terms of throughput, delivery ratio and delay by simulating realistic traffic on highway and urban roads through vehicular mobility simulator and network simulator.
