Resilience-Driven Parameterisation of Ad Hoc Routing Protocols: Olsrd as a Case Study

Download Now Free registration required

Executive Summary

Ad hoc routing protocols are threatened by a variety of accidental and malicious faults that limit their use. Although a number of well-known strategies exist to enhance the performance and resilience of such type of protocols, their final effectiveness strongly relies on the usage of appropriate protocol configuration parameters. This paper investigates how to parameterise ad hoc routing protocols to combine high performance, with acceptable levels of resilience and low consumption of resources. The research places the spotlight on olsrd, an ad hoc proactive routing protocol able to run on real devices and deploy challenge-response authentication, packet signature and fault tolerance strategies at runtime.
