Build wireless M2M and IoT sensor networks: Data dissemination

In the second in a four part series on implementation of wireless sensor networks the authors of “Ad hoc wireless networks,” discuss the various protocols required for reliable and fast data dissemination. Data dissemination is the process by which queries or data are routed in the sensor network. The data collected by sensor nodes has to be communicated to …

Build wireless M2M and IoT sensor networks: High quality and low power design

In the conclusion of a four part series, the authors of “Ad hoc wireless networks,” look at the remaining challenges in wireless sensor network design relating energy efficient hardware design, synchronization, transport layer protocols and real time communications. The purpose of a sensor network is to monitor and report events or phenomena taking place in a particular area. Hence, …

Build wireless M2M & IoT sensor networks: Data gathering & location detection

In the third of a four part series on implementation of wireless sensor networks, the authors of “Ad hoc wireless networks” go into detail about the techniques needed in the sensor nodes to discover their location and the specialized MAC protocols that need to be developed or modified. The objective of the data-gathering problem is to transmit the sensed …
