Emergence of two-dimensional (2D) materials with atomic-layer structures, such as graphene and MoS 2 , which have excellent physical properties, provides the opportunity of substituting silicon-based micro/nanoelectronics. An important issue before large-scale applications is the heat dissipation performance of these materials, especially when they are supported on a substrate, as in most scena...

The quantum transport computations have been carried on four different width of zigzag graphene using a nonequilibrium Green’s function method combined with density functional theory. The computed properties are included transmittance spectrum, electrical current and quantum conductance at the 0.3V as bias voltage.  The considered systems were composed from one-layer graphene sheets differing w...

Voice over Internet Protocol (VoIP), is a technology that allows you to make voice calls using a broadband Internet connection instead of a regular (or analog) phone line. VoIP services have compelling technical advantages over circuit switching. VoIP networks are based more on an open architecture than that of their circuit-switched contemporaries. This open, standards-based architecture means...

In this paper we perform initial study of SCTP performance in order to evaluate the idea of soft handover in the transport layer. We discuss two different aspects: the influence of the point between two adjacent Access Points to trigger the handover, and a set of triggering rules based on radio signal strength. From the experiments on triggering rules it was shown that the best trade-off betwee...

Recently, mobile SCTP (mSCTP) has been proposed as a transport layer approach for supporting mobility. mSCTP is based on the ’multi-homing’ feature of Stream Control Transmission Protocol (SCTP), and utilize the functions to dynamically add or delete IP addresses of end points to or from the existing connection in order to support mobility. In this paper, we propose a mechanism to determine whe...

Nowadays, anonymity and privacy protecting mechanisms are becoming more and more important. The anonymity of platforms and the privacy of users operating in the Internet are major concerns of current research activities. Although different techniques for protecting anonymity exist, standard protocols like Transport Layer Security are still missing adequate support for these technologies. In thi...

EXTENDED ABSTRACT Mobility, from the perspective of a network, is the ability to change network points of attachment. Support for mobility can be provided at the link layer (e.g. cell phones, 802.11) or at the network layer (e.g. Mobile IP). Link layer solutions are limited to point-to-point connectivity choices between the mobile and a base station. Network layer solutions are limited to infor...

It is a well known problem that errors and losses caused by unfavorable wireless link conditions cause problems for congestion controlled transport protocols such as TCP. TCP assumes that all losses occur due to network congestion. To remedy the perceived congestion, congestion avoidance is employed, typically by the TCP sender halving the sending rate. When congestion avoidance is incorrectly ...
