Wireless Sensor Networks (WSNs) have gained significant attention due to their wide range of applications. In these networks, the sensor nodes collect different types of data from the surrounding environment. There are many applications that require sensor node to transmit urgent data packets faster than normal data packets. In the literature, most of the available medium access control (MAC) protocols...
Supporting end-to-end quality of services for real-time interactive video applications such as videoconferencing and distance learning across the Internet requires a collection of independent networks or domains to work together to route packets between source and destination. Routing packets across the Internet using a feasible path - a path that meets the quality of service (QoS) attributes of video...
The Stream Control Transmission Protocol (SCTP) supports multiple streams to minimize the performance degradation due to head-of-line blocking. Among several streams transmitted simultaneously, some stream may require smaller transmission time than the others. However, the current SCTP provides no facility for controlling the access frequency of respective streams. This paper proposes a new scheme...
Managing VoIP service using QoS analysis is a vital issue for obtaining voice desired quality. Quality improvement and rational resource utilization are two parameters involved in determining VoIP service functionality. Which parameter outweighs the other one is a permanent challenge affecting developers' decisions. Hence every now and then different approaches are introduced impacting on VoIP service...
Next Generation Networks provide opportunities and challenges for data communication. In particular, the ever increasing bandwidth poses a major challenge to transport layer protocols such as TCP. In this paper the performance of TCP in large bandwidth delay networks, with particular regard to wireless network scenarios, is experimentally investigated. In particular we apply an accredited standard...
The goal of the Ship Data Network is to provide a broadband infrastructure as naval ships for convergence of real-time voice, data and video applications. Multicast of the data, voice and video from single source equipment to multiple equipment consumes less bandwidth. Unicast of data, voice, video will consume a lot of bandwidth of a network. So, a multicast philosophy and design that limits the...
We present Duo-MAC, an asynchronous cascading wake-up scheduled MAC protocol for heterogeneous traffic forwarding in low-power wireless networks. Duo-MAC deals with energy-delay minimization problem and copes with transmission latency encountered by Today's duty-cycled protocols when forwarding heterogeneous traffic types. It switches, according to the energy and delay requirements, between Low Duty...
Multicast services are used in emerging multimedia applications based on Quality of Service (QoS) development of multimedia group application and the construction of multicast routing tree is significant. Upper bound on the delay between sender and receiver is one of the common QoS constraints. Delay-constrained routing protocols are used to find paths subject to the delay constraint while efficiently...
In the context of networks providing QoS guarantees, the end-to-end delay experienced by a packet is an important parameter. In this paper, we show that network coding can be used to decrease worst case end-to-end bounds when compared to a classical routing strategy. This result can be explained by the fact that network coding can cope with congestion better that classical routing due to its property...
