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

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

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

    Abstract : This thesis compares a C++ prototype and an Erlang prototype for an Internet ofThings application. Internet of Things applications are difficult to program becausethey consist of a distributed environment of heterogeneous devices, where each devicecan have limited resources and connectivity technologies.

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

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling; Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

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

    Abstract : 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.

  5. 5. WSN Routing Schedule Based on Energy-aware Adaptation

    University essay from Mittuniversitetet/Institutionen för informationssystem och –teknologi

    Author : Tingqing Peng; [2020]
    Keywords : Multi-objective Optimization Problem; Routing schedule; KSP; Wireless sensor network;

    Abstract : In view of the problem of uneven load distribution and energy consumption among nodes in a multi-hop wireless sensor network, this research constructs the routing schedule problem as a MOP (Multi-objective Optimization Problem), and proposed an energy-aware routing optimization scheme RDSEGA based on multi-objective optimization. In this scheme, in order to avoid the searching space explosion problem caused by the increase of nodes, KSP Yen's algorithm was applied to prune the searching space, and the candidate paths selected after pruning are recoded based on priority.
