Implementation and analysis of the AODVv2 Routing Protocol in ARM devices.

AODVv2 is a well-known routing protocol used in MANETs (Mobile Ad hoc Networks). Formerly known as DYMO (DYnamic MANET On-demand), it is frequently used as a reference for routing protocols assessment. However, implementations of these protocols are scarce and the few ones available are currently outdated, no longer maintained and hardly upgradeable. This paper provides the details of a new AODVv2 implementation to be used in embedded devices working with the ARM microprocessor architecture. A user-space approach has been followed so both the upgradability and platform-independence are favored. A WiFi ad hoc network, modeling representative real scenarios, has been deployed to verify the correctness of the developed AODVv2 code and assess the performance of the protocol under realistic traffic conditions. A virtual machine has been used to perform a cross-compilation of a the code that implements the DYMO protocol in the Intel x86 computer architecture. Once compiled for being used in ARM-based devices, the code has been tested in Raspberry Pi devices to verify the proper behaviour. Simple scenarios and scenarios with high density of nodes have been deployed and data have been collected and analysed.
