1. 21. Measurements in opportunistic networks

   Författare :Fredrik Bjurefors; Per Gunningberg; Christian Rohner; 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 : Opportunistic networks are a subset of delay tolerant networks where the contacts are unscheduled. Such networks can be formed ad hoc by wireless devices, such as mobile phones and laptops. LÄS MER

3. 22. Extended mobile IP and support for global connectivity in hybrid networks

   Författare :Christer Åhlund; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mobile and Pervasive Computing; Distribuerade datorsystem;

   Sammanfattning : Mobility is an essential and necessary feature for roaming users who connect to wireless networks via access points. Access points may have different capabilities, be connected to different networks and be installed by different providers. A mobile host will discover multiple access points in this environment.

4. 23. Safety-oriented communication in mobile networks for vehicles

   Författare :Ioan Chisalita; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; vehicular communication; active safety systems; collision warning and avoidance; safety-related information; Computer science; Datavetenskap;

   Sammanfattning : Accident statistics indicate that every year a large number of casualties and extensive property losses are recorded due to traffic accidents. Consequently, efforts are directed towards developing passive and active safety systems that help reducing the severity of crashes or prevent vehicles to collide with each other. LÄS MER

5. 24. 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

7. 25. Mobility management in heterogeneous access networks

   Författare :Robert Brännström; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mobile and Pervasive Computing; Distribuerade datorsystem;

   Sammanfattning : This thesis proposes, describes and validates solutions to enhance mobility in heterogeneous access networks. Wireless access networks have become available almost everywhere and current research strives to make them pervasive. LÄS MER
