Sma home echnologies a e o en included as a pa o

Home echnologies ha e ied o help home inhabi an s

Domoweb [Ál a ez e al., 2005] is a esea ch p ojec
which was o iginally de eloped as a esiden ial ga eway
implemen a ion o e he OSGi (Open Se ices Ga eway
Ini ia i e) se ice pla o m. Domoweb implemen s he s an
da d se ices any esiden ial ga eway mus ha e like h p
se e , web in e aces, de ice manage , use manage and
o he basic se ices.
Nowadays Domoweb con o m a g ea pla o m whe e e
sea che s om di e en disciplines con e ges and whe e we
can deploy, de elop and es sma home ela ed solu ions,
due o he componen! based model, and he se ice o ien ed
a chi ec u e ha Domoweb and OSGi suppo s.
This a icle ocuses on modeling sma homes and he
ea u es he p edic ion algo i hms should implemen . A
good sma en i onmen model mus ep esen! he p ope 
ies, s a es, a ibu es and any o he cha ac e is ic ha could
be use ul in building sma en i onmen s solu ions as is
p oposed in sec ion 3.
A i icial in elligen me hods can be suppo ed by his
model like p edic ion algo i hms whe e is cen e ed his a i

2 Domoweb
The main goal o he Domoweb p ojec was o design and
de elop a sma home sys em con olled ía web and open
sou ce based. This objec i e means ha he home sys em
mus be able o manage ypical sma home elemen s like
ala ms, com o con ol, use s and o he sys em by means o
necessa y senso s and appliances.
One o he ea u es o he sys em is i s capaci y o being
managed h ough adap able in e aces so use s can con ol
he sma home om a huge a ie y o de ices. This con ol
usually in ol es in e ac ions wi h di e en echnologies like
Blue oo h, USB, o XIO so a special e o was necessa y o
communica e homogeneously wi h di e en echnologies.
Nex we discuss di e en design and implemen a ion deci
sions.
2.1 OSGi Se ice Pla o m implemen a ion
Domoweb is based on open sou ce implemen a ions so we
decided o use any o he a ailable implemen a ions. In pa 
icula we used wo e e ence implemen a ions: OSCAR1
(cu en ly known as Apache-Felix) and Knop le ish2. Bo h
pla o ms a e componen! and se ices o ien ed and show a
GUI whe e de elope s can deploy and manage componen s
in an independen way.
2.2 In as uc u e se ices
OSGi Se ice Pla o m p oposes speci ica ions o so ne
basic se ices any ga eway should implemen . Use admini
s a ion, con igu a ion adminis a ion and h p se e a e
good examples o hese essen ial se ices.
