Wireless communications offer an attractive option for many military, commercial as well as personal communication needs because of flexibility, cost effectiveness, and mobility. The quality features of wireless communications have led to tremendous growth in the demand for wireless networks and has led to development of novel technologies that raise the need for broadband wireless communicatio...

In this paper the end-to-end performance evaluation of a tagged session is considered through the study of a tandem queueing network. A service discipline is adopted at each queue which allows for the study of First-Come First-Served (FCFS) as well as peak-rate-enforcing multiplexing schemes. A numerical approach is presented which allows for the computation of delay, jitter and inter-departure...

Cell delay variation (CDV) is one of the quality of service parameters that can be negotiated between applications and an ATM network. The network should check during connection setup, as part of call admission control, whether it can satisfy the requested CDV of an application. For this comparison, the network should estimate the end-to-end CDV that it can support, by using local information a...

WirelessHART is a new standard specifically designed for real-time and reliable communication between sensor and actuator devices for industrial process monitoring and control applications. End-to-end communication delay analysis for WirelessHART networks is required to determine the schedulability of real-time data flows from sensors to actuators for the purpose of acceptance test or workload ...

Delay Tolerant Networks (DTNs) operate in a environment characterized by intermittently connected links and long, variable latency. End-to-end reliability schemes, such as TCP, perform poorly, or not at all, in this environment. Source node storage becomes a constrained resource when intermittent links have long downtimes or latency to receive acknowledgement from the destination is long. To al...

Mobile ad hoc networks range from traditional MANETs where end-to-end paths exist from sources to destinations, to DTNs where no contemporaneous end-to-end paths exist and communication is achieved by the store, carry, and forward model of routing. Hence, nodes of these networks need to identify the level of connectivity of the network they belong to and classify it as a MANET or a DTN, in orde...

Delay-Tolerant Networks (DTNs) have the potential to interconnect devices in regions that current networking technology cannot reach. The idea is that an end-to-end connection may never be present. To make communication possible, intermediate nodes take custody of the data being transferred and forward it as the opportunity arises. Both links and nodes may be inherently unreliable and disconnec...

Predicting the end-to-end packet delay and understanding the Internet dynamics are of great importance for many realtime and nonreal-time applications over the Internet, especially for the quality of service (QoS) provisioning and congestion control. After some preliminary statistical analysis, this paper presents a novel approach to predict the Internet end-to-end delay using multiple-model (M...

In these days interaction between different network applications are becoming more popular and to improve the speed and datatransfer rate delay difference between the multynetworks should minimize. In this paper we propose a Latency EQualization (LEQ) service, which equalizes the perceived latency for all clients participating in an interactive network application. The few routers used in LEQ c...

This paper proposes a stochastic model of an ATM based transport network layer of a UTRAN (UMTS Terrestrial Radio Access Network) that transmits the user data of different services such us voice, real time (RT) data and non-real time (NRT) data. Based on this stochastic model a numerical method is presented for the approximate analysis of end-to-end delay in UTRAN. A detailed discussion is prov...
