Efficient monitoring of the gas composition of the environment
with sensor networks which cover large territories and provide
continuous monitoring of combustible and toxic gases can be
regarded as a problem of special significance [1]. The primary aim
of a gas detection system is to warn about potential danger associated
with life hazard and material injury. There are a number of
relatively simple to highly sophisticated gas monitoring systems
which ensure early detection and warnings [2]. In this paper, we
focus our attention on gas sensors assembled and/or integrated in
a network.
