Real Time Operating Systems for Networked Embedded Systems


Fire Alarm System

Problem
Hundreds of sensors, each fitted with Low Range Wireless
Sensor information to be logged in a server & appropriate action initiated
Possible Solution
Collaborative Action
Routing
Dynamic – Sensors/controllers may go down
Auto Configurable – No/easy human intervention.
Less Collision/Link Clogging
Less no of intermediate nodes
Fast Response Time
Secure

ABSTRACT
In This Seminar An adaptive watermarking capacity analysis in the spatial domain and wavelet domain has to be present. The relationship between the watermarking capacity and the watermark detection error rate is also discussed. The discussion of watermark detection error rate will help us finding the ways to embed more watermark messages while keeping an acceptable detection error rate, it is useful for the design of the general algorithms of watermarking and detection. The watermarking system is analyzed based on the channel capacity ....etc

NAVSYS has developed a new Digital Antenna Element design for integration with a Controlled Reception Pattern Antenna (CRPA) which offers significant advantages over conventional Digital Antenna Electronics for high integrity GPS applications such as the Joint Precision Approach and Landing System (JPALS). Instead of performing spatial processing within the Digital Antenna Electronics, the Digital Antenna Elements each output the raw sampled digital data from each of the CRPA antenna raw sampled digital data from each of the CRPA antenna eleme ....etc

Mitigation of Control Channel Jamming under Node Capture Attacks



Abstract:

Availability of service in many wireless networks depends on the ability for network users to establish and maintain communication channels using control messages from base stations and other users. An adversary with knowledge of the underlying communication protocol can mount an efficient denial of service attack by jamming the communication channels used to exchange control messages. The use of spread spectrum techniques can deter an external adversa ....etc

Abstract—The protection of processor-based systems to mitigate the harmful effect of transient faults ( soft errors) is gaining importance as technology shrinks. At the same time, for large segments of embedded markets, parameters like cost and performance continue to be as important as reliability. This paper presents a compiler-based methodology for facilitating the design of fault-tolerant embedded systems. The methodology is supported by an infrastructure that permits to easily combine hardware/software soft errors mitigation techniques i ....etc
