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...
متن کاملAn Analysis of a Low Complexity Received Signal Strength Indicator for Wireless Applications
Wireless communication receivers work with radio frequency (RF) input signals with a huge dynamic range of 50dB and more. In order to provide the analog-to-digital converters (ADCs) in the receivers with an optimal signal strength, the gains of the RF and IF (intermediate frequency) stages have to be tuned according to the strength of the RF input signal. The RF input signal strength can be est...
متن کاملA Method for Eliminating Abnormal Values of Received Signal Strength Indicator (RSSI) in WLAN
Received signal strength indicator plays a very important role in many WLAN applications. However wireless signal strength will be greatly affected by noise and disturbance. It is critical to remove the abnormal data in order to provide a reliable estimation of the received signal strength indicator. Conventional mean value based approaches require large amount of data which would lead to unrel...
متن کاملReceived Signal Strength Indicator - Based Adaptive Localization Algorithm for Indoor Wireless Sensor Networks
Solutions for indoor localization have become more critical with recent advancement in context and location-aware technologies. When wireless sensor network (WSN) used in complex indoor environment, great propagation loss will be caused and it is very difficult to estimate adaptively the location of target nodes when environment changed. In this paper, an indoor adaptive localization algorithm ...
متن کاملRange-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...
