Journal ArticleDOI
Waveform substitution techniques for recovering missing speech segments in packet voice communications
TL;DR: In this article, the authors explore techniques for replacing missing speech with wave-form segments from correctly received packets in order to increase the maximum tolerable missing packet rate in voice communications.
Journal ArticleDOI
On the Vital Areas of Intrusion Detection Systems in Wireless Sensor Networks
TL;DR: A comprehensive classification of various IDS approaches according to their employed detection techniques is presented, and the three main categories explored in this paper are anomaly detection, misuse detection, and specification-based detection protocols.
Proceedings ArticleDOI
A robust dead-reckoning pedestrian tracking system with low cost sensors
TL;DR: A robust DR pedestrian tracking system on top of such commercially accessible sensor sets capable of DR, exploiting the fact that, multiple DR systems, carried by the same pedestrian, have stable relative displacements with respect to the center of motion, and therefore to each other.
Patent
Method of multiple access
TL;DR: In this article, a shared time-division duplexing (STDD) scheme is proposed to allow both uplink and downlink voice traffic to share a common channel by dynamically allocating time slots in the common information channel.
Journal ArticleDOI
Teletraffic performance of highway microcells with overlay macrocell
TL;DR: The teletraffic performance of a highway microcellular digital mobile radio system having an oversailing macrocell that spans many microcells is presented and a narrowband time-division-multiple-access arrangement supporting ten channels per carrier and one carrier per base station is used.
