Distributed shared memory shyam soni
Distributed shared memory (DSM) allows nodes in a cluster to access shared memory across the cluster in addition to each node's private memory. DSM uses a software memory manager on each node to map local memory into a virtual shared memory space. It consists of nodes connected by high-speed communication and each node contains components associated with the DSM system. Algorithms for implementing DSM deal with distributing shared data across nodes to minimize access latency while maintaining data coherence with minimal overhead.

9 virtual memory management
Virtual memory management techniques allow processes to access memory in a virtual address space that is larger than the actual physical memory. There are three main techniques:
1. Demand paging only loads pages into memory when they are needed, reducing I/O and memory usage but increasing access time due to page faults.
2. Copy-on-write shares pages between processes until a page is modified, then it is copied to avoid overwriting another process's page.
3. Page replacement algorithms select victim pages to remove from memory and write to disk when new pages are needed. Least recently used is commonly used but not optimal.

Fault tolerance in distributed systems
Fault tolerance is important for distributed systems to continue functioning in the event of partial failures. There are several phases to achieving fault tolerance: fault detection, diagnosis, evidence generation, assessment, and recovery. Common techniques include replication, where multiple copies of data are stored at different sites to increase availability if one site fails, and check pointing, where a system's state is periodically saved to stable storage so the system can be restored to a previous consistent state if a failure occurs. Both techniques have limitations around managing consistency with replication and overhead from checkpointing communications and storage requirements.
Hardware multithreading
This document discusses three types of hardware multithreading: coarse-grained, fine-grained, and simultaneous multithreading (SMT). Coarse-grained multithreading allows another thread to run during long stalls of the first thread. Fine-grained multithreading interleaves instructions from multiple threads in a round-robin fashion to hide stalls. SMT issues instructions from multiple threads in the same cycle by using register renaming and dynamic scheduling to maximize utilization.

Register allocation and assignment
This document discusses various strategies for register allocation and assignment in compiler design. It notes that assigning values to specific registers simplifies compiler design but can result in inefficient register usage. Global register allocation aims to assign frequently used values to registers for the duration of a single block. Usage counts provide an estimate of how many loads/stores could be saved by assigning a value to a register. Graph coloring is presented as a technique where an interference graph is constructed and coloring aims to assign registers efficiently despite interference between values.
Broadcast Models
There are 4 types of broadcast models: flat model, circular multi disk model, multi disk model, and skewed model. The flat model broadcasts data cyclically without considering subscriber numbers. The circular multi disk model repeats blocks proportionally to hierarchy and broadcasts blocks in a cycle. The multi disk model structures broadcast across multiple disks that spin at different rates. The skewed model clusters and organizes more important data together based on access frequency, placing most accessed data on the fastest disks.

Performance Analysis of TCP and SCTP For Congestion Losses In Manet
Transmission control protocols have been used for data transmission process. TCP has been pre-owned for data transmission over wired communication having different bandwidths and message delays over the network. TCP provides communication using 3-handshake which sends RTS and ACK comes from server end and data message has been transmitted over the bandwidth provided. This does not provide security over flooding attack occurred on the network. TCP provides communication between different nodes of the wired communication but when multi-streaming occurs in a network TCP does not provides proper throughput of the system which is major problem that occurred in the previous system. In the proposed work, to overcome this problem SCTP transmission control protocol has been implemented for the system performance of the system. SCTP provides 4-handshake communication in the message transmit due to which security factor get increases and this also provides communication services over multi-streaming and multi-homing. Multiple sender and receivers can communicate over wired network using various approaches of communication through same routers, which degrades in the TCP protocol. In final we evaluate parameters for performance evaluation. Here, we designed and implemented our test bed using Network Simulator (NS-2.35) to test the performance of both Routing protocols.

A Machine Learning based Network Sharing System Design with MPTCP
The information and communication technologies (ICT) integrate different types of wireless communication to
provide IT-enabled services and applications. The great majority end devices are equipped with multiple network
interfaces such as Wi-Fi and 4G. Our goal is to integrate the available network interfaces and technologies to
enhance seamless communication efficiency and increase resources utilization. We proposed a heterogeneous
network management algorithm based on machine learning methods which includes roaming and sharing
functions. The roaming function provides the multiple network resources in physical and media access control
layers. The sharing function supports multiple network resources allocation and the service handover process
based on the Multi-Path TCP protocol. The simulation result also shows that the proposed scheme can increase
the network bandwidth utilization effectively. The sharing system could be used in home, mobile and vehicular
environments to realize ubiquitous social sharing networks.

The document summarizes a proposed scheduling technique called Real Time Conflict-free Query Scheduling (RTCQS) for wireless sensor networks. RTCQS aims to increase throughput for high data rate sensor applications while supporting real-time queries. It uses a query planner to construct transmission plans for queries as sequential conflict-free steps. A query scheduler then schedules the query instances, using preemption for higher priority queries or concurrent execution when no conflicts exist. The goal is high throughput, low latency, and adaptability to varying workloads.

Improved SCTP Scheme To Overcome Congestion Losses Over Manet
Transmission control conventions have been utilized for data transmission process. TCP has been pre-possessed
for information transmission over wired correspondence having diverse transfer speeds and message delays over
the system. TCP gives correspondence utilizing 3-handshake which sends RTS and ACK originate from server
end and information message has been transmitted over the data transmission gave. This does not give security
over flooding assault happened on the system. TCP gives correspondence between distinctive hubs of the wired
correspondence however when multi-spilling happens in a system TCP does not gives legitimate throughput of
the framework which is significant issue that happened in the past framework. In the proposed work, to beat this
issue SCTP and Improved SCTP transmission control convention has been executed for the framework
execution of the framework. SCTP gives 4-handshake correspondence in the message transmit and improved
SCTP gives the performance when the queue length comes to its full value then it divides the message to other
nodes because of which security element get expansions and this likewise gives correspondence administrations
over multi-spilling and multi-homing. Numerous sender and recipients can impart over wired system utilizing
different methodologies of correspondence through same routers, which debases in the TCP convention. In last
we assess parameters for execution assessment. Here, we composed and actualized our proving ground utilizing
Network Simulator (NS-2.35) to test the execution of both Routing conventions.
REAL-TIME ROUTING PROTOCOLS FOR WIRELESS SENSOR NETWORKS: A SURVEY
Wireless sensor networks can be termed as a new generation of distributed embedded systems
that has a capability of meeting broad range of real-time applications. Examples include
radiation monitoring, fire monitoring, border surveillance, and medical care to name but a few.
Wireless sensor networks that are deployed in time/mission-critical applications with highly
dynamic environments have to interact with the physical phenomenon under stringent timing
constraints and severe resource limitations. For such real-time wireless sensor networks,
designing and developing a real-time routing protocol that meets the required real-time
guarantee of data packets communication is a stimulating field of study that raised many
challenges and research issues. In this paper, we present a comprehensive survey of real-time
routing protocols in WSN, by discussing each protocol with its key features. Finally, we concluded this paper with open research issues and challenges of real-time routing in WSN.

Iaetsd an effective approach to eliminate tcp incast
This document proposes an Incast Congestion Control for TCP (ICTCP) scheme to eliminate TCP incast collapse in datacenter environments. TCP incast collapse occurs when multiple synchronized servers send data to the same receiver in parallel, overwhelming the switch buffer and causing packet loss. ICTCP is a receiver-side approach that proactively adjusts the TCP receive window size of connections to control their aggregate burstiness and prevent switch buffer overflow before packet loss occurs. It estimates available bandwidth and uses this as a quota to coordinate receive window increases. For each connection, the receive window is adjusted based on the ratio of the difference between measured and expected throughput. This allows adaptive tuning of receive windows to meet sender throughput needs while avoiding congest

The document provides information on various networking concepts:
- A switch connects multiple devices on a local network, while a router connects separate networks and forwards data between them. A firewall acts as a security barrier between a local network and the internet.
- DNS translates domain names to IP addresses so web browsers can load internet resources by interacting with DNS servers.
- An IP address is a unique string of numbers that identifies devices on a network or the internet.
- TCP is a connection-oriented protocol that provides reliable data delivery and error checking, while UDP is connectionless and does not guarantee delivery.
MANET, Unicast Routing Protocol, Multicast Routing Protocol.
In the last few years, video streaming facilities over TCP or UDP, such as YouTube, Facetime, Daily-motion, Mobile video calling have become more and more popular. The important
challenge in streaming broadcasting over the Internet is to spread the uppermost potential quality,
observe to the broadcasting play out time limitation, and efficiently and equally share the offered
bandwidth with TCP or UDP, and additional traffic types. This work familiarizes the Streaming
Media Data Congestion Control protocol (SMDCC), a new adaptive broadcasting streaming
congestion management protocol in which the connection’s data packets transmission frequency is
adjusted allowing to the dynamic bandwidth share of connection using SMDCC, the bandwidth share
of a connection is projected using algorithms similar to those introduced in TCP Westwood. SMDCC
avoids the Slow Jump phase in TCP. As a result, SMDCC does not show the pronounced rate
alternations distinguishing of modern TCP, so providing congestion control that is more appropriate
for streaming broadcasting applications. Besides, SMDCC is fair, sharing the bandwidth equitably
among a set of SMDCC connections. Main benefit is robustness when packet harms are due to
indiscriminate errors, which is typical of wireless links and is becoming an increasing concern due to
the emergence of wireless Internet access. In the presence of indiscriminate errors, SMDCC is also
approachable to TCP Tahoe and Reno (TTR). We provide simulation results using the ns3 simulator
for our protocol running together with TCP Tahoe and Reno.

An improved modulation technique suitable for a three level flying capacitor ...
This research paper introduces an innovative modulation technique for controlling a 3-level flying capacitor multilevel inverter (FCMLI), aiming to streamline the modulation process in contrast to conventional methods. The proposed
simplified modulation technique paves the way for more straightforward and
efficient control of multilevel inverters, enabling their widespread adoption and
integration into modern power electronic systems. Through the amalgamation of
sinusoidal pulse width modulation (SPWM) with a high-frequency square wave
pulse, this controlling technique attains energy equilibrium across the coupling
capacitor. The modulation scheme incorporates a simplified switching pattern
and a decreased count of voltage references, thereby simplifying the control
algorithm.

Comparative analysis between traditional aquaponics and reconstructed aquapon...
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

- 2. INTRODUCTION Real time system is one in which the correctness of the computations not only depends on their logical correctness but also on the time on which the result is produced. Real-time communications (RTC) is a term used to refer to any live telecommunications that occur without transmission delays. RTC is nearly instant with minimal latency. Basic concepts: Jitter Timeliness Bandwidth Loss rate
- 3. TYPES OF NETWORK In real time communication three types of networks are important: Controller Area Network Local Area Network Internet
- 4. CONTROLLER AREA NETWORK CANs are very small networks. These are typically used to connects the different components of embedded controllers. The end-to-end length of a CAN is usually less than 50 meters. LOCAL AREA NETWORK LAN is a network within a building or a campus and is usually privately owned. A LAN is used to connect a number of computers within an organization to share data and other resources such as a printer, file etc. INTERNET The Internet is a worldwide system of computer networks
- 5. TOPOLOGY Network topology is the topological structure of a network and may be depicted physically or logically. There are following topologies Bus TOPOLOGY In local area networks where bus topology is used, each node is connected to a single cable, by the help of interface connectors.
- 6. STAR TOPOLOGY In local area networks with a star topology, each network host is connected to a central hub with a point-to-point connection. So it can be said that every computer is indirectly connected to every other node with the help of the hub. MESH TOPOLOGY Every device has a dedicated point to point link to every other device.
- 7. HARD AND SOFT REAL TIME COMMUNICATION Hard Real Time Communication Hard real time system is a real time system that must meet its deadlines. Hard real-time systems, the level of tolerance for a missed deadline is extremely small or zero tolerance. Soft Real Time Communication In soft real time system, missed deadline does not result in a system failures but cost can rise in proportion to the delay depending on the application. the level of tolerance is non-zero
- 8. RESOURSE RESERVATION PROTOCOL The Resource Reservation Protocol (RSVP) is a transport layer protocol designed to reserve resources across a network for quality of service (QoS) using the integrated services model. RSVP operates over an IPv4 or IPv6 and provides receiver-initiated setup of resource reservations for multicast or unicast data flows. RSVP can be used by hosts and routers to request or deliver specific levels of QoS for application data streams or flows.
- 9. MODE OF REAL TIME COMMUNICATION HALF DUPLEX In half-duplex RTC, data can be transmitted in both directions on a single carrier or circuit but not at the same time. Example : CB Radio, Walkie-takie FULL DUPLEX In full-duplex RTC, data can be transmitted in both directions simultaneously on a single carrier or circuit. Example: telephone, Social networking, video conffrencing
