LoRaWAN‐implemented node localisation based on received signal strength indicator

Range-free sensor localisation with ring overlapping based on comparison of received signal strength indicator

Sensor localization has become an essential requirement for many applications over wireless sensor networks. Radio irregularity and stringent constraints on hardware cost and battery power, however, make localization very challenging. Range-based localization depends on special-purpose hardware for direct measurement of the distance to reference points. Range-free localization, in contrast, doe...

Received Signal Strength Indicator Node Localization Algorithm Based on Constraint Particle Swarm Optimization

Because the received signal strength indicator (RSSI) value greatly changes, the direct use of RSSI value has more errors in the positioning process as the basis to calculate the position of anchor nodes. This paper proposes a RSSI node localization algorithm based on constraint particle swarm optimization (PSO-RSSI). In the algorithm, particle swarm optimization is used to select anchor nodes ...

Maritime Management Using Received Signal Strength Indicator

For location finding through Wireless Sensor Networks (WSNs), the RSSI is regularly assumed to have a linear signal strength by the whole of the logarithm of the communication distance. However, this is not true in certain cases because there are uncertainties in RSSI readings to obstacles, receiver interferences etc. In this complimentary, we specifically ask for the hand of a new RSSI-based c...

Using received signal strength indicator to detect node replacement and replication attacks in wireless sensor networks

With the advent of powerful and efficient wireless sensor nodes, the usage of wireless sensor networks (WSNs) has been greatly increased. However, various kinds of security breaches have also been introduced, which exposes the vulnerability of these nodes to defend the valuable data from some specific types of attacks. In this paper, we address node replication, replacement, and man-in-the-midd...
