A Vehicular Ad-Hoc Networks (VANETs) are technology that uses moving cars as nodes in a network to create a mobile network. VANET turns every participating car into a wireless router, allowing cars of each other to connect and create a network with a wide range. VANETs are developed for enhancing the driving safety and comfort of automotive users. The VANETs can provide wide variety of services...

With the advances of wireless communication technologies, wireless networks gradually become themost adopted communication networks in the new generation Internet. Computing devices and mobile devices may be equipped with multiple wired and/or wireless network interfaces. Stream Control Transmission Protocol (SCTP) has been proposed for reliable data transport and its multihoming feature makes ...

Congestion control in Signaling System #7 faces new challenges as mobile communication systems and Intelligent Networks grow rapidly. New services change traffic patterns, add to signalling network load, and raise demands on shorter service completion times. To handle new demands, the congestion control mechanisms must foresee an overload situation, and respond to it so that the network can mai...

The Internet telephony employs a new type of Internet communication on which a mutual communication is realized by establishing sessions. Session Initiation Protocol (SIP) is used to establish sessions between end-users. For unreliable transmission (UDP), SIP message should be retransmitted when it is lost. The retransmissions increase a load of the SIP signaling network, and sometimes lead to ...

In this paper, we describe a new approach to decreasing communication overhead: splintering. In contrast to OS bypass, the principle of splintering isn’t that the operating system shouldn’t be used, but that it should be used effectively. In the case of communication offload, the goal is to minimize the overhead associated with invoking the OS while still enabling the OS to control communicatio...

The increasing popularity of group communication applications such as teleconference and information dissemination services has led to a great deal of interest in the development of multicast transport protocols layered on top of IP multicast. However, these new transport protocols could cause congestion collapse if they are widely used but do not provide adequate congestion control. In this pa...

Future high-speed computer communication networks are expected to utilize Asynchronous Transfer Mode (ATM) technology. In order to broadly deploy ATM-based networks, numerous congestion control mechanisms are presently being developed by the industry and research community alike. In this paper, we propose a general method to evaluate the performance of a given congestion control scheme by obser...

In all types of communication network, congestion is always an important issue. Congestion in wireless network cause loss of packets, longer delay and throughput degradation. In applications like multimedia, nodes typically produce large amount of data necessitates high transmission rates and more processing, a fundamental concern in Wireless Multimedia Sensor Networks. Many sources send data o...

Asynchronous parallel computing can result in high message generation rates, thus triggering network congestion. This paper investigates the network congestion problem that can result from asynchronous parallel programs' high message generation rates. First, we characterize the communication requirements of a large class of supercomputing applications falling under the category of xed-point pro...
