  1. 16. Data Aggregation and Gathering Transmission in Wireless Sensor Networks: A Survey

    University essay from Högskolan i Jönköping/JTH, Data- och elektroteknik

    Author : phani priya kakani; [2013]
    Keywords : Data aggregation in hierarchical networks; Secure data aggregation; Purpose of data aggregation and gathering in wireless sensor networks;

    Abstract : Wireless sensor networks have many sensor devices that send their data to the sink or base station for further processing. This is called direct delivery. But this leads to heavy traffic in the network and as the nodes are limited with energy, this decreases the lifetime of the network. READ MORE

  3. 17. Efficient Key Generation and Distributionon Wireless Sensor Networks

    University essay from KTH/Kommunikationsnät

    Author : Victor Arino Perez; [2013]
    Keywords : ;

    Abstract : Wireless Sensor Networks have become popular during the last years. The introduction ofIPv6 which broadened the address space available, IEEE802.15.4 and adaption layers such as6loWPAN have allowed the intercommunication of small devices. READ MORE

  4. 18. An Energy-Balancing Unequal Clustering Algorithm for Multi hop Routing in WSN

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Sheima Hassan Elamin Hamed; [2013]
    Keywords : Multi-hop routing; Energy balancing; Linear optimization; Network lifetime; Unequal clustering; Wireless Sensor Networks;

    Abstract : Energy saving is a critical issue in Wireless Sensor Networks as they have limited amount of energy and no rechargeable batteries. Clustering plays an effective role in utilization and saving of the limited energy resources of the deployed sensor nodes, where nodes are grouped into clusters and one node, called the cluster head is responsible for collecting data from other nodes, aggregates them and sends them to the BS, where data can be retrieved later.

  5. 19. Ethernet Energy Harvesting

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Sukru Senli; [2012]
    Keywords : Ethernet Energy Harvesting; Energy Harvesting; Energy Scavenging; Ethernet Power;

    Abstract : Improvements in embedded electronics which have effectively reduced power consumption requirements as well as advancements in IC technology allowing utilization of low power inputs have made Energy Harvesting a popular power solution for low power applications such as WSNs. In many implementation areas, we can see solar, thermal, and vibration energy harvesting techniques have taken the role of batteries as power source. READ MORE

  6. 20. A Performance Evaluation of RPL in Contiki

    University essay from Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

    Author : Hazrat Ali; [2012]
    Keywords : RPL; Routing metrics; Cooja; Objective Function; Evaluation; Low Power and Lossy Networkk;

    Abstract : A Wireless Sensor Network is formed of several small devices encompassing the capability of sensing a physical characteristic and sending it hop by hop to a central node via low power and short range transceivers. The Sensor network lifetime strongly depends on the routing protocol in use. READ MORE
