In this paper we present methods to reach 10-years of battery life for Industrial Internet of Things (IIoT) wireless sensor network (WSN) using a platform called the I3Mote. I3Mote provides connected sensor nodes for tough industrial environment and a number of I3Motes can form a large-scale coverage of data collectors or actuators. The goal is to achieve 10-years network life time for all the connected...
Wireless Sensor Networks (WSNs) are used for monitoring and data collection purposes. A key challenge in effective data collection is to schedule and synchronize the activities of the nodes with global clock. This paper proposes the Synchronized Data Aggregation Algorithm (SDA) using spanning tree mechanism. It provides network-wide time synchronization for sensor network. In the initial stage algorithm...
Structural health monitoring (SHM) is of great significance for ensuring the using functions, safety operation of buildings and extending service lifetime of buildings. The structural damage detection is the main work of the structural health monitoring. In this paper, we proposed a new online structural damage detection method called N-stage Kalman Filter Algorithm (NS-Kalman). Its main idea is to...
Wireless Sensor Network for their rapid deployment can be used in habitat monitoring for detecting fire and in disaster for helping rescue teams. Node localization is key factor for some applications. We propose the Triangular Centroid Localization algorithm (TCL). It is based in simple trigonometric figures and it does not require special hardware or synchronization time. In our simulations using...
In monitoring wireless sensor networks (WSNs) with event-driven applications, the generated traffic usually has bursty characteristics when an event occurs. Transient congestion in the networks would increase delay and packet loss rate severely, reducing the network performance greatly. Through the analysis on delay and packet loss rate in congestion, this paper proposes a congestion-aware mac protocol...
For improving throughput and energy efficiency in wireless sensor networks, multi-channel media access control has been proposed. Existing multi-channel MAC protocols are mainly focus on channel assignment and media access, it means that a senor node is bound with one channel, which makes the whole network inflexible and cannot be adapted to the variations of environment. In this paper, we proposed...
The objective of Synchronization In wireless sensor network is to synchronize the various sensor nodes which are distributed as well as moving in a network. Synchronization is an important problem in communication networks especially for real time applications. There may be one base station of 1000 sensor nodes moving in the network. Synchronization is considered a particularly difficult in wireless...
Shrinking size and increasing deployment density of wireless sensor nodes implies to smaller equipped battery size. This means emerging wireless sensor nodes must compete for efficient energy utilization. MAC protocols play a vital role in energy consumption of sensor node as it controls the radio activities. Customized or open source simulators play an important role to measure the performance effectiveness...
Flooding time synchronization protocol (FTSP) is an extendable, robust and steady protocol, which has high synchronization precision in wireless sensor networks. This paper improves the traditional FTSP, according to the characteristics of industrial wireless sensor networks. The key idea is that the node should avoid transmitting the time synchronization message with the rootID and seqNum, which...
This paper introduces a new dynamic addressing technique for prolonging the operational duration of duty cycled wake-up radios found in wireless sensor networks. A wireless sensor network (WSN) consists of a field of spatially distributed wireless nodes which operate on minimal battery power for extremely long times. A WSN typically uses a multi-hop architecture where messages containing sensed data...
