“…Second, it presents a way to make the verification topology independent, avoiding a proof based on a particular scenario. Third, the method presents a way to safely model flooding based protocols, avoiding the combinatorial state space explosion problem [16]. Fourth, to decrease the protocol verification complexity, the method proposes divide the verification into internal and external protocol behavior.…”

This paper describes a technique to apply formal methods to verify protocols for mobile ad hoc networks. In contrast to other related proposals, our solution does not attempt to model any particular network configuration. Instead, our solution focuses on the possible implications caused by network configurations to the behavior of a routing protocol for MANETs. Following this strategy we were able to find design errors in some well established protocols. The proposed technique uses formal verification, more specifically model checking, to detect, in a simple way, problems such as routing loops, delivery message failures and errors in the protocol state machine.

Partial order reduction is a very succesful technique for avoiding the state explosion problem that is inherent to explicit state model checking of asynchronous concurrent systems. It exploits the commutativity of concurrently executed transitions in interleaved system runs in order to reduce the size of the explored state space. Directed model checking on the other hand addresses the state explosion problem by using guided search t e c hniques during state space exploration. As a consequence, shorter errors trails are found and less search e ort is required than when using standard depth-rst or breadth-rst search. We analyze how to combine directed model checking with partial order reduction methods and give experimental results on how the combination of both techniques performs.

“…Compared with the development of state space reduction techniques that preserve a given equivalence, design for verifiability is a rather novel concept because the validity of the reduction is in the hand of the designer. The best we could find is , but it primarily addresses improvements in verification technology, too. A recent plea similar to ours is , where it is argued that systems must be programmed such that analysis of those systems becomes much simpler.…”

SUMMARYDuring the last two decades, we modelled the behaviour of a large number of systems. We noted that different styles of modelling had quite an effect on the size of the state spaces of the modelled systems. The differences were so substantial that some specification styles led to far too many states to verify the correctness of the model, whereas with other styles, the number of states was so small that verification was a straightforward activity. In this article, we summarize our experience by providing seven specification guidelines to keep state spaces small. For each guideline, we provide an application, generally from the realm of traffic light controllers, for which we provide a 'bad' model with a large state space, and a 'good' model with a small state space. The good and bad models are both suitable for their purpose but are not behaviourally equivalent. For all guidelines, we discuss circumstances under which it is reasonable to apply the guidelines.
