Modelling of a hybrid protocol for a MANET using fuzzy Petri Nets

Mobile Ad hoc networks are formed by devices that can communicate with each other using a wireless physical medium without pre-existing infrastructure. Each node can function not only as end systems, but also as intermediate systems providing connectivity and data path to the other nodes. This can be realizable through designing of comprehensive and functional routing protocols. Petri Net models allow compact representations of multiple interacting components and can describe the behaviour of several concurrent components modelled as tokens marking the structure. Fuzzy Petri Nets implement fuzzy rule-based reasoning using proposition logic to model systems which have incomplete information about state and time. The present paper analyzes a hybrid routing protocol by calculating the level of firing among the nodes and comparing it with a threshold value for the nodes of the network. Finally, the simulation indicates enhanced performance and dynamically viable node movement.
