1. 11. Detailed simulation of heterogeneous wireless sensor networks

   Författare :Joakim Eriksson; Thiemo Voigt; Per Gunningberg; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

   Sammanfattning : Wireless sensor networks consist of many small nodes. Each node has a small microprocessor, a radio chip, some sensors, and is usually battery powered which limits network lifetime. Applications of wireless sensor networks range from environmental monitoring and health-care to industrial automation and military surveillance. LÄS MER

3. 12. Implementation and real-world evaluation of routing protocols for wireless ad hoc networks

   Författare :Henrik Lundgren; Per Gunningberg; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

   Sammanfattning : A wireless ad hoc network consists of a number of mobile nodes that temporarily form a dynamic infrastructure-less network. To enable communication between nodes that do not have direct radio contact, each node must function as a wireless router and potentially forward data traffic on behalf of the others. LÄS MER

4. 13. Tools and methods for evaluation of overlay networks

   Författare :Olof Rensfelt; Lars-Åke Larzon; Per Gunningberg; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

   Sammanfattning : Overlay networks is a popular method to deploy new functionality which does not currently exist in the Internet. Such networks often use the peer-to-peer principle where users are both servers as well as clients at the same time. We evaluate how overlay networks performs in a mix of strong and weak peers.

5. 14. Opportunistic Networking : Congestion, Transfer Ordering and Resilience

   Författare :Fredrik Bjurefors; Per Gunningberg; Christian Rohner; Mario Gerla; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Opportunistic Networking; Congestion; Transfer Ordering; Resilience; Testbed; WISENET; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

   Sammanfattning : Opportunistic networks are constructed by devices carried by people and vehicles. The devices use short range radio to communicate. Since the network is mobile and often sparse in terms of node contacts, nodes store messages in their buffers, carrying them, and forwarding them upon node encounters. LÄS MER

7. 15. Towards adaptive sensor networks

   Författare :Niclas Finne; Thiemo Voigt; Per Gunningberg; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

   Sammanfattning : Wireless sensor networks consist of many small embedded devices that are equipped with sensors and a wireless communication unit. These devices, or sensor nodes, are typically low cost, resource constrained and battery-powered. LÄS MER
