Markov-based analytical modeling has been used extensively to model the operation of the MAC protocol of the IEEE 802.15.4 standard under diverse assumptions. These models reveal the parameters that control the behavior of each node in the network such as end-to-end latency, reliability and power consumption. Focusing on improving a certain metric is highly dependent on the type of application the...
The use of Wireless Sensor Networks (WSNs) to monitor and control power utility assets in the smart grid is gaining increasing popularity due to their various desirable features. WSNs with multihop cluster tree topologies solve the limited coverage problem of sensor nodes. However, in smart grid monitoring applications, data rates could increase suddenly due to the occurrence of critical faults in...
Wireless Sensor Networks (WSNs) are emerging as promising tools to aid in monitoring the smart grid. WSNs can be easily deployed in a wide number of smart grid assets such as substations, overhead power lines and power generation sites. They offer ubiquity and flexibility at a low-cost. However it may be difficult to offer the Quality of Service (QoS) demanded by the smart grid applications with WSNs...
In critical infrastructure monitoring applications, the packet arrival rates of a Wireless Sensor Network (WSN) may abruptly increase when cascaded failures are observed in the monitored environment. WSNs with cluster-tree topologies could experience excessive delays because of this increase in packet arrival rates. Therefore, there should be an optimum operating point in the network where the network...
