Loop freedom is an important property for distance vector routing protocols, especially for the protocols of ad hoc network because the topologies are dynamic. This paper gives a formal description of the AODV protocol and presents a strictly formal proof of its loop freedom property in Isabelle/HOL. The proved theorem states that no loop will exist in any number of nodes. The result demonstrates...
This paper shows how event-driven software architecture may facilitate easy debugging. Most existing replay-based debugging techniques involve tool developments. Drawbacks for such techniques are two-fold: (1) extra cost for tool development. (2) lack of availability, tools and techniques for one platform might not be available or applicable on other platforms. This paper tries to improve the situation...
