A Comprehensive Analysis of Packet Loss in MANETs

2018 17th IEEE International Conference On Trust, Security And Privacy In Computing And Communications/ 12th IEEE International Conference On Big Data Science And Engineering (TrustCom/BigDataSE), 2018
Security schemes proposed for for Mobile Ad hoc Networks (MANETs) based on node's trust computation consider packet drop as a sign of misbehaving from malicious nodes. However, this may not be always true because of node mobility and limited processing capability feature of nodes in MANETs. As nodes are free to move in MANETs, packet loss may occur due

On end-to-end analysis of packet loss

Computer Communications, 2003
End-to-end analysis of packet loss is presented, addressing both overall packet loss rate and loss correlations. Voice over IP is used as an application for which packet loss performance is analyzed. In addition to independent packet losses, concepts of temporal and spatial- or across-the-domain-correlations are analyzed and their applicability to end ...

Analysis of audio packet loss in the internet

1995
We consider the problem of distributing audio data over networks such as the Internet that do not provide support for real-time applications. Experiments with such networks indicate that audio quality is mediocre in large part because of excessive audio packet losses.

On the Packet Loss Process at a Network Node

2006
It is a well known fact that the packet loss ratio is an important but insufficient measure to assess the influence of packet loss on user perceived quality of service in telecommunication networks. In this paper we therefore assess other loss process characteristics of finite capacity Markov-modulated M/M/1-type buffers.

A comparison of packet loss compensation methods and interleaving for speech recognition in burst-like packet loss

Interspeech 2004, 2004
This work compares the performance of three compensation methods for speech recognition in the presence of packet loss. Two methods, cubic interpolation and a novel maximum a posteriori (MAP) estimation, aim to restore the feature vector stream in the event of packet loss, while the third technique applies compensation in the decoding stage of ...

Adaptive packet parity coding for loss-packet recovery

2009 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing, 2009
An adaptive packet parity coding is proposed for recovering the loss packets over packet loss network links. For every (n-1) packets of data, this coding scheme transmits an error-correcting packet that contains the XOR of the previous (n-1) packets of data.

Packet Loss Analysis in Mobile IP

2004
Packet loss and packet disorder are two important factors which badly affect handoff performance of Mobile IP. In this paper, we study their probabilities in the case of cell overlap and no overlap, and use these results to optimize the radius of overlap region. In addition, some illustrations show that our model conforms to our observation perfectly.

Evaluation of packet loss probability in Bluetooth networks

2002 IEEE International Conference on Communications. Conference Proceedings. ICC 2002 (Cat. No.02CH37333), 2003
We provide a closed-form expression for the packet loss probability in Bluetooth networks accounting for capture effects due to propagation losses. The effectiveness of the proposed approach is assessed comparing the analytical results with those obtained from Monte Carlo simulations.

Study of packet loss in a packet switched voice system

IEEE International Conference on Communications, - Spanning the Universe., 2003
A study is presented of the temporal behavior of packet loss on a voice-transmitted TDM time-division multiplexed link. The mean duration is given of blocking and nonblocking periods, the variance of blocking periods, and the expected packet. The loss rate within blocking periods is derived.
