Efficient Data Collection Over Multiple Access Wireless Sensors Network. (arXiv:1712.03314v2 [cs.IT] UPDATED)
来源于:arXiv
Data collection in Wireless Sensor Networks (WSN) draws significant
attention, due to emerging interest in technologies raging from Internet of
Things (IoT) networks to simple "Presence" applications, which identify the
status of the devices (active or inactive). Numerous Medium Access Control
(MAC) protocols for WSN, which can address the challenge of data collection in
dense networks, were suggested over the years. Most of these protocols utilize
the traditional layering approach, in which the MAC layer is unaware of the
encapsulated packet payload, and therefore there is no connection between the
data collected, the physical layer and the signaling mechanisms. Nonetheless,
in many of the applications that intend to utilize such protocols, nodes may
need to exchange very little information, and do so only sporadically, that is,
while the number of devices in the network can be very large, only a subset
wishes to transmit at any given time. Thus, a tailored protocol, which matches
