Abstract

Data availability is an important issue for self-organizing systems, which include both Peer-to-Peer (P2P) systems and mobile ad hoc networks (MANETs). In P2P systems, the problem of data availability is solved by replicating data across the network. However, this approach wastes resources, and so is not appropriate for MANETs where resource frugality is essential. Unlike P2P systems, MANETs routing protocols require real-time features to cope with a highly dynamic environment, and efficient synchronization mechanisms to guarantee consistent updates of routing information. Unfortunately, due to the semantics of the languages that are most used in network programming, such mechanisms are extremely hard or even impossible to implement in efficient way. To build an application capable of meeting almost all of these requirements, while providing a framework capable of evolving over time, we propose an approach that is based on DSA.
