  1. 16. Compact Object Security for the Internet of Things

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

    Author : Joakim Brorsson; Martin Gunnarsson; [2016]
    Keywords : Internet of Things; Object Security; Constrained Devices; CoAP; OSCoAP; Technology and Engineering;

    Abstract : The Internet of Things is coming. With it comes security challenges not present on common, more capable, devices such as desktop computers or servers. We argue that traditional channel security needs to be complemented with object security to cope with the constrained nature of small devices and Low Power Lossy Networks. READ MORE

  3. 17. Real-time Coding for Kinesthetic and Tactile Signals

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Liyang Zhang; [2016]
    Keywords : ;

    Abstract : The Tactile Internet is at the core of the 5G era, when the world will experience paradigm shift from content-delivery networks to service/labour-delivery ones. Systems that enable wireless communications of haptic data feature bi-directionality, high packet rate and resolution, large degrees of freedom, and above all, strict latency requirements in many applications, aggravating the shortage of wireless resources.

  4. 18. Implementing Linear Predictive Coding based on a statistical model for LTE fronthaul

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

    Author : Ghassan Nakkoul; Mohammad Shohag Hassan Kaikobad; [2016]
    Keywords : Entropy; LTE fronthaul; RRH; BBU; C-RAN; Quantization; LTE downlink; Cyclic prefix; LPC; EVM; OFDM; Linear predicting coding; LTE; Technology and Engineering;

    Abstract : This thesis studies the application of Linear Predictive coding (LPC) in the downlink of Long Term Evolution (LTE) fronthaul, which comprises of BBU and RRH. This can act as an additional module in the existing system. Today, the transmission of a single complex sample from the BBU to the RRH consumes 30 bits. READ MORE

  5. 19. Battery Lifetime Modelling and Validation of Wireless Building Automation Devices in Thread

    University essay from KTH/Kommunikationsnät

    Author : Eva Azoidou; [2016]
    Keywords : Internet of Things IoT ; battery lifetime; wireless sensor networks; energy efficiency; IEEE 802.15.4 MAC; power consumption model; Thread;

    Abstract : The need for energy efficiency in wireless communication is prevalent in all areas, but to an even greater extent in low-power and lossy networks that rely on resource-constrained devices. This degree project seeks to address the problem of modelling the battery lifetime of a duty-cycled node, participating in a wireless sensor network that is typically used in smart home and building applications.

  6. 20. Video Quality of Experience through Emulated Mobile Channels

    University essay from Blekinge Tekniska Högskola/Institutionen för kommunikationssystem

    Author : NARAYANA KAILASH AMUJALA; JOHN KENNEDY SANKI; [2014]
    Keywords : H.264 SVC; AWGN noise; Downlink power; QoE problems; User Interface.;

    Abstract : Over the past few years, Internet traffic took a ramp increase. Of which, most of the traffic is video traffic. With the latest Cisco forecast it is estimated that, by 2017 online video will be highly adopted service with large customer base. As the networks are being increasingly ubiquitous, applications are turning equally intelligent. READ MORE
