Various tools, which are capable to evade different security mechanisms like firewall, IDS and IPS, exist and that helps the intruders for sending malicious traffic to the network or system. So, inspection of malicious traffic and identification of anomalous activity is very much essential to stop future activity of intruders which can be a possible attack. In this paper we present a flow based system...
Multimedia Broadcast Multicast Service (MBMS) architecture enables the efficient usage of radio-network and core network by sharing the network resources. But the efficient usage of resources has not been discussed for the scenario where source and destination of the MBMS service belongs to the same Gateway General Packet Radio Service support node (GGSN) which means that one of the user equipment...
Transmission Control Protocol was designed to work over the networks characterized by low delay and negligible bit error rates. Transmission Control Protocol (TCP) performance degrades when TCP traffic is carried over the satellite networks that have large latency, high bit error rates and path asymmetry. To comprehend the effect of satellite conditions over TCP, we have evaluated the TCP performance...
An adjustable polarization mode dispersion compensator with a variable tapered-3D-hollow-waveguide Bragg-reflector has been demonstrated exhibiting a giant-birefringence of 0.01 and a 13-psec tuning in differential-group-delay for a 3-mm-long compact device.
This work presents a 32 nm SOI CMOS technology featuring high-k/metal gate and an SRAM cell size of 0.149 mum2. Vmin operation down to 0.6 V in a 16 Mb SRAM array test vehicle has been demonstrated. Aggressive ground rules are achieved with 193 nm immersion lithography. High performance is enabled by high-k/metal gate plus innovation on strained silicon elements including embedded SiGe and dual stress...
A tapered-3D-hollow-waveguide Bragg-reflector has been proposed exhibiting a giant-birefringence of 0.01 and an 8.5-psec tuning in differential-group-delay for 3-mm-long compact devices, which can be used for adjustable compensation of polarization-mode-dispersion in optical-fiber-links.
This paper presents a novel architecture for a high speed finite impulse response (FIR) filter. The design of proposed filter is based on a computation sharing multiplier algorithm with reduced addition implementation. The proposed filter is very efficient, as it gives a significant improvement in speed with a reduction in size of adder circuits. The performance of the proposed filter is compared...
Service-oriented architectures (SOAs) promise to provide transparency to resource access by exposing the resources available as services. SOAs have been employed within pervasive computing systems to provide essential support to user tasks by creating services representing the available resources. The mechanism of combining two or more basic services into a possibly complex service is known as service...
