Hardware implementation of OLSR and improved OLSR (AOLSR) for AANETs

Abstract

Airborne Ad-hoc Networks (AANETs) are a subclass of Vehicular Ad-hoc Networks (VANETs). The major challenge in AANET implementation is the regular route breaks due to very high mobility of aircraft. To deal with this routing challenge in AANETs, we have designed a new protocol named Airborne OLSR (AOLSR) which is based on more optimisation of the MPR selection technique used in existing OLSR protocol. A hardware implementation of any protocol is always crucial for the validation of its design. So, this manuscript also provides a hardware implementation of both OLSR and AOLSR protocols using Verilog. The node architectures for both the protocols have been implemented in Vivado. The node's sub-component implementation area, execution time and total power consumption have been used as parameters to compare their performance. The simulation analysis shows that the proposed AOLSR performs better as compared to OLSR in terms of total power consumption and execution time.
