1. 6. High-Level Control of UAV Swarms with RSSI Based Position Estimation

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Märta Paulsson; [2017]
   Keywords : Technology and Engineering;

   Abstract : Search and rescue operations can greatly benefit from the use of cooperative swarms of autonomous UAVs in order to investigate areas and collect information about the position of a missing person. In this thesis, UAV swarm algorithms are investigated where collisions are prevented both between agent pairs and between agents and static obstacles. READ MORE

3. 7. Outdoor localization in long range WSN using trilateration

   University essay from Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska fakulteten

   Author : Tom Karlsson; Mike Persson; [2017]
   Keywords : ;

   Abstract : This thesis report investigates how good position estimations that can be done outdoors with received signal strength indication (RSSI) trilateration for sub 1-GHz radio nodes. A custom network and an empirical distance model have been created as well as a technique for weighting multiple distance estimations, using wrapped normal probability density functions. READ MORE

4. 8. Evaluation and Improvement of the RSSI-based Localization Algorithm : Received Signal Strength Indication (RSSI)

   University essay from Blekinge Tekniska Högskola/Institutionen för programvaruteknik

   Author : Alireza Shojaifar; [2015]
   Keywords : RSSI algorithm; indoor localization; Wireless Sensor Network WSN ; RSSI filtering; RSSI distance error; localization algorithm;

   Abstract : Context: Wireless Sensor Networks (WSN) are applied to collect information by distributed sensor nodes (anchors) that are usually in fixed positions. Localization (estimating the location of objects) of moving sensors, devices or people which recognizes the location’s information of a moving object is one of the essential WSN services and main requirement.

5. 9. A Diagnostic Tool for the Causes of Packet Corruption in Wireless Sensor Networks

   University essay from Mittuniversitetet/Avdelningen för informations- och kommunikationssystem

   Author : Wenxuan Jiang; [2015]
   Keywords : Wireless Sensor Network; Packets Corruption; RSSI; Logistic Regression;

   Abstract : The two main causes of packet corruption in wireless sensor network are multipath fading and WiFi interference. Identifying the cause of the corruption can be used to improve the reliability of the transmission. If the corruption is caused by WiFi interference, the network could change the channel to a free one. READ MORE

6. 10. Using Multilateration and Extended Kalman Filter for Localization of RFID Passive Tag in NLOS

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Iyeyinka Damilola Olayanju; Olabode Paul Ojelabi; [2010]
   Keywords : RFID; passive tag; RTLS; NLOS; Multilateration; Extended Kalman Filter;

   Abstract : The use of ubiquitous network has made real time tracking of objects, animals and human beings easy through the use of radio frequency identification system (RFID). Localization techniques in RFID rely on accurate estimation of the read range between the reader and the tags. READ MORE
