1. 1. Implementation and performance analysis of multiple concurrent WPAN protocols on a system-on-chip

   Master-uppsats, Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakulteten

   Författare :Juni Hag; [2022]
   Nyckelord :Bluetooth; Bluetooth Low Energy; BLE; Zigbee; 802.15.4; IEEE 802.15.4; WPAN; wireless protocols; sensor networks; IoT; Internet of Things; multiprotocol; TDMA; SoC;

   Sammanfattning : The development of new energy efficient Wireless Personal Area Network (WPAN) protocols is a big factor for the increased interest in Internet of Things (IoT). However, the many protocols with overlapping applications have led to competing standards and sensor networks using different protocols, even to perform the same tasks. LÄS MER

3. 2. Erlang as an alternative to a non-functional language for communication in a faulttolerant IoT sensor network

   Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

   Författare :Jimmy Holdö; [2020-02-17]
   Nyckelord :Internet of Things; Wireless Sensor Network; Erlang; IEEE 802.15.4; ZigBee; Network topology;

   Sammanfattning : This thesis compares a C++ prototype and an Erlang prototype for an Internet of Things application. Internet of Things applications are difficult to program because they consist of a distributed environment of heterogeneous devices, where each device can have limited resources and connectivity technologies.

5. 4. A Multi-layered Routing Technique for Sensing Train Integrity and Composition

   Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Författare :Satya Venkata Sidhi Vinayak Pulugurtha; Kishore Kumar Atragadda; [2020]
   Nyckelord :Cargo Wagon; Composition; Integrity; Scalability; Wireless Sensor Network;

   Sammanfattning : This thesis deals with an approach to monitor the integrity and composition of cargo wagons withthe help of Wireless Sensor Network (WSN). The WSN is to be fully automated that does notneed any human intervention for gathering information about the composition and integrity ofcargo trains, which are the most necessary factors for Cargo Logistics.

7. 5. Enhancing Zigbee Security for Industrial Implementation

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Hamza Kadhum; [2020]
   Nyckelord :Zigbee network security; LoWPAN; IoT; Wireless Sensor Network; Node lifetime; Zigbee nätverk säkerhet; LoWPAN; IoT; Trådlöst Sensornätverk; Sensornodens livslängd;

   Sammanfattning : Zigbee network is a popular choice for deploying low power personal area network (LoWPAN). The application areas vary but the most popular are industrial area monitoring and home automation. But Zigbee has been identified to have weak security and is not applicable for industrial implementation. LÄS MER
