ad hoc networks are multi-hop wireless networks without a pre-installed infrastructure. such networks are widely used in military applications and in emergency situations as they permit the establishment of a communication network at very short notice with a very low cost. video is very sensitive for packet loss and wireless ad-hoc networks are error prone due to node mobility and weak links. h...

This contribution discusses the general problem of modelling packet loss distribution in IP networks, and is intended to provide input to Q.12 study of IP network behaviour and background material for the Q.8 and Q.16 groups. The factors that cause packet loss and packet discard within jitter buffers are generally transient in nature, typically related to congestion or link failure. This leads ...

In this paper, we consider packet switching problems in bipartite concentrators under the assumption that more than one packet/slot can be processed through a fabric crosspoint. We use three packet-processing models to derive the packet loss and throughput in a bipartite concentrator. The following paper is an extended summary which presents the models and main results. We expect to provide a m...

The current paper investigates the influence of packet losses in network control systems (NCS’s) using the model predictive control (MPC) strategy. The study focuses on two main network packet losses due to sensor to controller and controller to actuator along the communication paths. A new Markov-based method is employed to recursively estimate the probability of time delay in controller to ac...

In this paper we analyze the packet loss process in a single server queueing system with a nite buuer capacity. The model we use addresses the packet loss probabilities for packets within a block of consecutive sequence of packets. In contrast to other work which used an independence assumption to compute the loss probabilities of packets within a block, we present an analytical approach that y...
