Modelling intelligent and reliable ferry routes in Wireless Sensor Networks using polling systems theory

This paper proposes a new model for finding intelligent and reliable ferry routes using a continuous polling system to ensure a better transportation of messages between wireless nodes and the corresponding sink. We consider that the Wireless Sensor Network (WSN) is composed by wireless static sensor nodes and several mobile ferries that collect information from all the sensors in the network. We have used a pure birth process to model the reliability aspect of the nodes in the network. We have considered several cases: with one ferry and N ferries moving in the same area. We have studied the impact of nodes density and the faulty rate occurrence to find the best and reliable path for the mobile ferry to cover all the nodes of the WSN.
