Abstract

The innate dynamicity and complexity of mobile ad-hoc networks (MANETs) has resulted in numerous adhoc routing protocols being proposed. Furthermore, numerous variants and hybrids continue to be reported in the literature. This diversity appears to be inherent to the field- it seems unlikely that there will ever be a 'one-size-fitsall' solution to the ad-hoc routing problem. However, typical deployment environments for ad-hoc routing protocols still force the choice of a single fixed protocol; and the resultant compromise can easily lead to sub-optimal performance, depending on current operating conditions. In this paper, we address this problem by exploring a framework approach to the construction and deployment of ad-hoc routing protocols. Our framework supports the simultaneous deployment of multiple protocols so that MANET nodes can switch protocols to optimise to current operating conditions. The framework also supports finer-grained dynamic reconfiguration in terms of protocol variation and hybridisation. We evaluate our framework by using it to construct and (simultaneously) deploy two popular ad-hoc routing protocols (DYMO and OLSR), and also to derive fine-grained variants of these. We measure the performance and resource overhead of these implementations compared to monolithic ones, and find the comparison to be favourable to our approach.
