    Abstract : With the advent of new multimedia applications the demand for in time delivery of data is increased as compared to the reliability. Usually the Transport Layer Protocols, User Datagram Protocol (UDP) and Transmission Control Protocol (TCP) are used to transfer the data over the IP based network like Internet. READ MORE

  4. 3. Simultaneous Mobility Management in Seamless Handover by using mobile SCTP (mSCTP)

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

    Author : Md. Ibrahim Chowdhury and Mohamad Iqbal; [2010]
    Keywords : mSCTP; Simultaneous Mobility; Location Management; Handover Latency; Location Server LS ; step_length; NS-2.;

    Abstract : This thesis proposes a new solution approach for the simultaneous mobility issues in seamless handover for next generation wireless networks and envisages the vision of seamless roaming in IP mobility. Simultaneous mobility problem occurs while both of the communicating mobile nodes (MNs) change their location simultaneously and consequently losing their corresponding binding updates. READ MORE

  5. 4. A Flexible Framework for Hierarchical Clustering on Wireless Sensor Networks

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

    Author : Yi Gong; [2010]
    Keywords : ;

    Abstract : In Wireless Sensor Networks, a clustering algorithm is a good option to reduce redundant data transmission and organize nodes efficiently for long life span. In this thesis, we mainly introduce, implement and evaluate a novel flexible hierarchical clustering algorithm on middleware layer based on Publish/Subscribe paradigm. READ MORE
