Reliability Analysis of Wireless Sensor Networks Using Markovian Model

Abstract EN

This paper investigates reliability analysis of wireless sensor networks whose topology is switching among possible connections which are governed by a Markovian chain.

We give the quantized relations between network topology, data acquisition rate, nodes' calculation ability, and network reliability.

By applying Lyapunov method, sufficient conditions of network reliability are proposed for such topology switching networks with constant or varying data acquisition rate.

With the conditions satisfied, the quantity of data transported over wireless network node will not exceed node capacity such that reliability is ensured.

Our theoretical work helps to provide a deeper understanding of real-world wireless sensor networks, which may find its application in the fields of network design and topology control.
