Abstract

In this work we propose a new energy efficient and faulttolerant protocol for data propagation in wireless sensornetworks, the Variable Transmission Range Protocol VTRP.The basic idea of data propagation in VTRP is the varyingrange of data transmissions, ie. we allow the transmissionrange to increase in various ways. Thus data propagationin our protocol exhibits high fault-tolerance (by bypassingobstacles or faulty sensors) and increases network lifetime(since critical sensors, ie. close to the control center arenot overused). As far as we know, it is the first time varyingtransmission range is used.We implement the protocol and perform an extensive experimentalevaluation and comparison to a representativeprotocol (LTP) of several important performance measureswith a focus on energy consumption. Our findings indeeddemonstrate that our protocol achieves significant improvementsin energy efficiency and network lifetime.
