It however may fail to capture the uniqueness of the energy-constrained applications in wireless sensor networks. Although a sensor node is expected to work through a long time, it is often not required to work all the time, i. As sensor data constitute the major traffic in the network, wireless interferences and collisions are mostly occurring in the data delivery stage, which has more impacts on the MAC layer and thus generally leads to cross-layer designs among the MAC, network and transport layer as discussed in this section. Johnson, J. Yet a more challenging issue is that sensor nodes are operating autonomously, thus the transmission scheduling algorithm needs to be designed to work in a distributed manner. In these systems, sensors are deployed at specified locations to fulfill the civil engineering requirements.

To suppress duplicate forwardings, a node only schedules forwarding when it receives a broadcast message for the first time. Indeed, even in a less harsh environment like wild habitat or a building, the threats from rodents are still critical and make the protection of wires much more difficult than that of sensors. In these applications, sensor nodes are often alternating between dormant and active states; in the former, they go to sleep and thus consume little energy, while in the latter, they actively perform sensing tasks and communications, consuming significantly more energy e.

However, if heavy packet loss happens or the network topology changes due to dynamics such as link quality variations, the hop-by- hop recovery may fail due to the temporary overflow of missing lists or losing connections to prto piggy-back their information in its transmissions. Ideally, if without wireless communication loss, every sensor node needs to receive and forward the broadcast message at most once. To reduce sleeping latency as well as energy costs, thevious forwarders. Guna, M. In area monitoring, the WSN is deployed over a region where some phenomenon is to be monitored.

Seielstad, and S. Download your Full Reports for Wireless Sensor Network Wireless sensor network A wireless sensor network WSN is a computer network consisting of spatially distributed autonomous devices using sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants, at different locations. On the other hand, in gossiping, received messages are only forwarded with some pre-defined probability. In addition to one or more sensors, each node in a sensor network is typically equipped with a radio transceiver or other wireless communications device, a small microcontroller, and an energy source, usually a battery. Yet another kind of typical requirement is location-coverage, where sensor nodes must be attached to some specific locations that are chosen carefully by applications. Kim, S.
