The increase in cellular users (CU) caused data traffic congestion on the Base Station (BS). Device to (D2D) communication can be used reduce BS. D2D is direct between devices without using a central BS congestion. CU and will share same Resource Block (RB), but there drawback that causes interference. This study employs downlink direction Heterogeneous Network (HetNet) system model mitigate in...

In this paper, we study the problem of scheduling parallel loops at compile-time for a heterogeneous network of machines. We consider heterogeneity in three aspects of parallel programming: program, processor and network. A heterogeneous program has parallel loops with different amount of work in each iteration; heterogeneous processors have different speeds; and a heterogeneous network has dif...

The rapid roll out of e-commerce applications and the drive for m-commerce applications has caused the boundaries between traditional telecommunications and computer communications and storage to break down. This has lead to heterogeneous networks, mixing traditional voice and new Internet communication and storage technologies. The Web Based Enterprise Management (WBEM) initiative proposes to ...

This report addresses the issue of writing reliable numerical software for networks of heterogeneous computers. Much software has been written for distributed memory parallel computers and in principal such software could readily be ported to networks of machines, such as a collection of workstations connected by Ethernet, but if such a network is not homogeneous there are special challenges th...

We describe ways in which the transmission control protocol of the Internet may evolve to support heterogeneous applications. We show that by appropriately marking packets at overloaded resources and by charging a fixed small amount for each mark received, end-nodes are provided with the necessary information and the correct incentive to use the network efficiently.

The wireless communication with delivering variety of services to users is growing rapidly in recent years. The third generation of cellular networks (3G), and local wireless networks (WLAN) are the two widely used technologies in wireless networks. 3G networks have the capability of covering a vast area; while, WLAN networks provide higher transmission rates with less coverage. Since the two n...

This paper provides a congestion control mechanism under heterogeneous network and analyze the TCP’s represented research achievements and current situation problems under heterogeneous environment. According to the shortage of the TCP under heterogeneous network, we design TCP congestion control algorithm based on model bandwidth estimation to solve the problem of heterogeneous network switchi...

A flexible intermediate library named Stampi for MPI-2 support on a heterogeneous computing environment has been implemented on an SCore cluster system. With the help of a flexible communication mechanism of this library, users can execute MPI functions without awareness of underlying communication mechanism. In message transfer of Stampi, a vendor-supplied MPI library and TCP sockets are used ...
