  1. 1. Efficient Security Protocol for RESTful IoT devices

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Karnarjun Kantharajan; Sahar Shirafkan; [2020]
    Keywords : Internet of Things IoT ; TLS 1.2 1.3; DTLS 1.2; OSCORE; CoAP; Security Protocols.; Technology and Engineering;

    Abstract : In this thesis, we presented comparisons with respect to Energy Consumption, bandwidth, the Constraint application protocol (CoAP) transaction time and throughput for four different security protocols. We simulated and implemented the Datagram Transport Layer Protection (DTLS) version 1.2, Transport Layer Protocol (TLS) version 1.2 & 1. READ MORE

  4. 3. Multi-Channel Anypath Routing for Multi-Channel Wireless Mesh Networks

    University essay from Fakulteten för ekonomi, kommunikation och IT

    Author : Andreas Lavén; [2010]
    Keywords : Multi-Channel Anypath Routing Wireless Mesh Network;

    Abstract : Increasing capacity in wireless mesh networks can be achieved by using multiple channels and radios. By using different channels, two nodes can send packets at the same time without interfering with each other. To utilize diversity of available frequency, typically cards use channel-switching, which implies significant overhead in terms of delay. READ MORE

  5. 4. Comparative Analysis of Performance Routing Metrics for Multi-radio Wireless Mesh Networks

    University essay from Blekinge Tekniska Högskola/Avdelningen för telekommunikationssystem

    Author : Akum Nji Ivo; [2008]
    Keywords : multi-radio; Wireless Mesh Networks; Routing metrics; Wireless multi-hop networks; Multi-channel; performance;

    Abstract : Traditional Ad Hoc network wireless communication in the past years have contributed tremendously to the dawn of wireless mesh networks (WMNs) which have so far been able to provide a significant improvement in capacity and scalability. Routing metrics which form the basic element for the routing protocol in this innovative communication technology is a call for concern as they must take into consideration the wireless medium network characteristics in order to provide a optimum appreciable QoS performance.

  6. 5. UWB Measurement Techniques and RF Coexistence in a Mobile Handset

    University essay from Institutionen för teknik och naturvetenskap; Tekniska högskolan

    Author : Erik Holmgren; [2006]
    Keywords : ;

    Abstract : There are two typical interference problems in a multi-radio platform, i.e. blocking due to the saturation of the front end of a receiver by the high power radiation from another transmitter, and desensitization of the receiver by the in-band noise generated by the other transmitter. The UWB device is not an exception. READ MORE
