Abstract(s)
Wireless Sensor Networks (WSNs) have been attracting
increasing interests in the development of a new generation of embedded
systems with great potential for many applications such as surveillance,
environment monitoring, emergency medical response and home
automation. However, the communication paradigms in Wireless
Sensor Networks differ from the ones attributed to traditional wireless
networks, triggering the need for new communication protocols and
mechanisms. In this Technical Report, we present a survey on
communication protocols for WSNs with a particular emphasis on the
lower protocol layers. We give a particular focus to the MAC
(Medium Access Control) sub-layer, since it has a prominent influence
on some relevant requirements that must be satisfied by WSN
protocols, such as energy consumption, time performance and
scalability. We overview some relevant MAC protocol solutions and
discuss how they tackle the trade-off between the referred requirements.
