MANET in Mobile Computing
MANET is a type of mobile ad hoc network that is self-configuring and infrastructureless, allowing mobile devices to connect without wires. Nodes in a MANET can join or leave the network freely, making the network topology dynamic. Each node acts as both a host and router to forward data. MANETs support multi-hop routing to allow communication between nodes out of direct wireless range. They offer advantages like scalability, low cost, and access to information anywhere but also face challenges like variable wireless link quality, low data rates, and partitioned networks due to node movement.
AODV routing protocol
The document discusses several routing protocols for mobile ad hoc networks:
- DSR allows nodes to cache and share routing information for more efficient routing but has larger packet headers due to source routing. AODV uses only next hop information, keeping routing tables smaller.
- Both protocols use route discovery and maintenance, but AODV proactively refreshes routes while DSR reacts to failures. AODV also uses sequence numbers to prevent loops and choose fresher routes.
- Overall, DSR is better for networks where routes change infrequently while AODV scales better and maintains only active routes, at the cost of higher routing overhead during route discovery. Security remains a challenge for both protocols.

DPRoPHET in Delay Tolerant Network
PRoPHET uses its delivery predictability of node encounters and transitivity to forward bundles to its neighbor node. Regardless of their distance, it faces delivery dilemmas in a source node and drawbacks of low delivery ratio and high delay in case two or more neighbor nodes carry equal delivery predictability. To solve such consequences, we propose a Distance and Probabilistic Routing Protocol using History of Encounters and Transitivity (DPRoPHET) with the use of cross layer implementation for distance value retrieval. Our simulation results show that, by adding distance metric to the existing delivery predictability vector, DPRoPHET outperforms PRoPHET.

VCN: Vehicular Cloud Network Using RBMR Protocol for Efficient Link Stability...
VCN is Vehicular Cloud Network which is the combination of VANET and cloud. Vehicular ad hoc networks (VANETs) technology has been used in many of the applications such as avoiding traffic jam on roadways and airways, preventing the vehicles from accidents and so on. It serve as one of the best platform to meet with group-oriented services which comes under one of the primary application classes. Multicast routing is used to support such services. In such cases one must have to ensure better packet delivery ratio, lower delays and reduced control overheads. Thus, there is a need to design stable and reliable multicast routing protocols for VANETs. In this paper, we proposed a Receiver Based Multicast Routing Protocol that finds a best way to perform the multicast traffic. RBMulticast stores destination list inside the packet header, this destination list provides information on all multicast members to which this packet is targeted .And it stores the traced information or data in the cloud for given period of time. Thus, the multicast tree is not required for this process and therefore no tree state stored at the intermediate nodes.

However, designing reliable VANETs presents challenges related to security, scalability, high mobility, and environmental factors that affect wireless communication. Recent research focuses on developing intelligent transportation systems using VANETs to assist drivers with safety and provide applications for traffic efficiency and infotainment.

A Survey on Vehicular Ad hoc Networks
Abstract: Vehicular Ad hoc Networks (VANETs), a subclass of mobile ad hoc network (MANET), is a
promising approach for the intelligent transport system (ITS). VANET allows vehicles to form a self-organized
network without the need for a permanent infrastructure. As the VANET has a potential in improving road
safety, real time traffic update and other travel comforts, it turns attention of the researcher. Though VANET
and MANET shares some common characteristics like self-organized network, dynamic topology, ad hoc nature
etc, VANET differs from MANET by challenges, application, architecture, power constraint and mobility
patterns, so routing protocols used in MANET are not applicable with VANET. New routing strategy for VANET
has been proposed by many researchers in recent year. This paper provides focus on the various aspects of
VANET like architecture, characteristic, challenges, glimpse of routing protocols, and simulation models used
for VANET.

Communications in Vehicular networks
Recent advances in wireless networks have led to the introduction of a new type of networks called Vehicular Networks. Vehicular Ad Hoc Network (VANET) is a form of Mobile Ad Hoc Networks (MANET). VANETs provide us with the infrastructure for developing new systems to enhance drivers’ and passengers’ safety and comfort. VANETs are distributed self organizing networks formed between moving vehicles equipped with wireless communication devices. This type of networks is developed as part of the Intelligent Transportation Systems (ITS) to bring significant improvement to the transportation systems performance. One of the main goals of the ITS is to improve safety on the roads, and reduce traffic congestion, waiting times, and fuel consumptions. The integration of the embedded computers, sensing devices, navigation systems (GPS), digital maps, and the wireless communication devices along with intelligent algorithms will help to develop numerous types of applications for the ITS to improve safety on the roads. The up to date information provided by the integration of all these systems helps drivers to acquire real-time information about road conditions allowing them to react on time. For example, warning messages sent by vehicles involved in an accident enhances traffic safety by helping the approaching drivers to take proper decisions before entering the crash dangerous zone (ElBatt et al., 2006) (Xu et al., 2007). And Information about the current transportation conditions facilitate driving by taking new routes in case of congestion, thus saving time and adjusting fuel consumption (Dashtinezhad et al., 2004) (Nadeem et al., 2004). In addition to safety concerns, VANET can also support other non-safety applications that require a Quality of Service (QoS) guarantee. This includes Multimedia (e.g., audio/video) and data (e.g., toll collection, internet access, weather/maps/ information) applications.
Vehicular networks are composed of mobile nodes, vehicles equipped with On Board Units (OBU), and stationary nodes called Road Side Units (RSU) attached to infrastructure that will be deployed along the roads.

Abstrct of ivc
Inter-vehicle communication enables intelligent transportation systems and provides driver assistance services by allowing vehicles to communicate with each other and with roadside equipment. Vehicular ad-hoc networks (VANETs) are a new type of wireless network that spontaneously forms between moving vehicles using short to medium range wireless communication. VANETs allow vehicles to share information to provide safety and convenience applications to drivers and passengers.
Cognitive Radio For Vehicular Adhoc Networks
Cognitive radio technology allows wireless devices to intelligently access and use available radio frequency spectrum. When applied to vehicular ad hoc networks (VANETs), cognitive radio can improve communication reliability and safety. By dynamically adapting to the changing radio environment, cognitive radio enables vehicles to communicate using available spectrum bands. This results in more efficient communication between vehicles and infrastructure, reducing collisions and improving traffic flow. However, challenges remain around efficient spectrum management, security, and standardization that researchers are working to address in order to fully realize the benefits of cognitive radio for VANETs.
VANET in Mobile Computing
Vehicular ad-hoc networks (VANETs) allow vehicles to communicate with each other using sensors, GPS, WiFi and other technologies. In a VANET, vehicles act as wireless routers to connect to other vehicles within 100-300 meters, creating a mobile internet. VANETs provide safety benefits by sharing information about location, speed and road conditions to warn of accidents and traffic. They can also notify drivers of nearby services. Inter-vehicle communication does not require infrastructure and allows real-time sharing of safety messages between any vehicles that are nearby.

multi threaded and distributed algorithms
The document discusses multithreaded and distributed algorithms. It describes multithreaded algorithms as having concurrent execution of parts of a program to maximize CPU utilization. Key aspects include communication models, types of threading, and performance measures. Distributed algorithms do not assume a central coordinator and are run across distributed systems without shared memory. Examples of distributed algorithms provided are breadth-first search, minimum spanning tree, naive string matching, and Rabin-Karp string matching.
Amortized analysis
Amortized analysis gives the average performance of algorithms over many operations, rather than analyzing each operation individually. There are three main methods: aggregate analysis assigns costs to operations to find an upper bound cost; accounting assigns costs but allows "credits" from low-cost operations to pay for high-cost ones; potential assigns costs and uses potential energy differences rather than credits. Examples discussed include binary and binomial heaps, randomized quicksort, and approximation algorithms for NP-complete problems that provide fast, near-optimal solutions.
Complexity theory
This document provides an overview of complexity theory concepts including:
- Asymptotic notation like Big-O, Big-Omega, and Big-Theta for analyzing algorithm runtime.
- The difference between deterministic and non-deterministic algorithms, with deterministic algorithms always providing the same output for a given input, and non-deterministic algorithms possibly providing different outputs.
- The classes P and NP, with P containing problems solvable in polynomial time by a deterministic algorithm, and NP containing problems verifiable in polynomial time by a non-deterministic algorithm.
- NP-complete problems being the hardest problems in NP, with examples like the knapsack problem, Hamiltonian path problem, and Boolean satisfiability problem.
Divide and Conquer
The document discusses the divide and conquer algorithm design paradigm. It begins by defining divide and conquer as recursively breaking down a problem into smaller sub-problems, solving the sub-problems, and then combining the solutions to solve the original problem. Some examples of problems that can be solved using divide and conquer include binary search, quicksort, merge sort, and the fast Fourier transform algorithm. The document then discusses control abstraction, efficiency analysis, and uses divide and conquer to provide algorithms for large integer multiplication and merge sort. It concludes by defining the convex hull problem and providing an example input and output.
Model and Design

CUDA allows developers to speed up applications by offloading work to the GPU. It provides a scalable parallel programming model that maps threads to GPU threads to express data-level parallelism across thousands of lightweight threads for applications like high-bandwidth computing and visual computing.
Parallel Algorithms- Sorting and Graph
This document discusses parallel algorithms for sorting and graph problems. It covers parallel implementations of sorting algorithms like bubble sort, quicksort, and parallel compare-exchange and compare-split operations. For graphs, it discusses parallel depth-first search by partitioning the search space, all-pairs shortest paths problems, and algorithms for sparse graphs. It also briefly mentions parallel breadth-first search and parallel best-first search.
Analytical Models of Parallel Programs
This document discusses analytical models for parallel programs. It covers sources of overhead in parallel programs like load imbalance and dependencies. It defines performance metrics like execution time and overhead functions. It discusses how granularity affects performance and the scalability of parallel systems. It provides examples of optimizing dense matrix algorithms like matrix-vector and matrix-matrix multiplication. The goal is to determine minimum execution times and costs by analyzing parallel runtimes as a function of problem size and number of processors.
Basic Communication
This document discusses various communication patterns in parallel and distributed systems including one-to-all broadcast, all-to-one reduction, all-to-all broadcast and reduction, all-reduce, prefix-sum, scatter, gather, and circular shift operations. It describes how to perform these operations efficiently using techniques like recursive doubling and message splitting. Improving the performance of common communication operations can be done by splitting large messages into smaller parts and combining different patterns like scatter, all-to-all, and gather.
Parallel Processing Concepts
This document discusses parallel programming and algorithm design. It covers principles of parallel algorithms like decomposing computations into simultaneous tasks. It describes task decomposition techniques like data, recursive, exploratory and speculative decomposition. It also discusses mapping techniques to distribute tasks across processes, characteristics of tasks, and parallel algorithm models like data-parallel, task graph, work pool, master-slave, and producer-consumer. Finally, it briefly introduces GPU computing and references.
Parallel Processing Concepts
This document discusses parallel processing concepts including:
1. Parallel computing involves simultaneously using multiple processing elements to solve problems faster than a single processor. Common parallel platforms include shared-memory and message-passing architectures.
2. Key considerations for parallel platforms include the control structure for specifying parallel tasks, communication models, and physical organization including interconnection networks.
3. Scalable design principles for parallel systems include avoiding single points of failure, pushing work away from the core, and designing for maintenance and automation. Common parallel architectures include N-wide superscalar, which can dispatch N instructions per cycle, and multi-core which places multiple cores on a single processor socket.
Dynamic programming
Dynamic programming is an algorithm design technique that solves problems by breaking them down into smaller subproblems. It is useful for problems that exhibit optimal substructure and overlapping subproblems. Some examples of problems solved using dynamic programming include the optimal binary search tree problem, the 0/1 knapsack problem, and matrix chain multiplication. Dynamic programming works by storing the results of subproblems to avoid recomputing them, building up to the overall optimal solution.
Parallel algorithms
This document discusses parallel algorithms and models of parallel computation. It begins with an overview of parallelism and the PRAM model of computation. It then discusses different models of concurrent versus exclusive access to shared memory. Several parallel algorithms are presented, including list ranking in O(log n) time using an EREW PRAM algorithm and finding the maximum of n elements in O(1) time using a CRCW PRAM algorithm. It analyzes the performance of EREW versus CRCW models and shows how to simulate a CRCW algorithm using EREW in O(log p) time using p processors.
Greedy method
The document discusses greedy algorithms and how they can be applied to solve optimization problems like the knapsack problem, activity selection problem, and job sequencing problem. It provides examples of greedy algorithms for each problem. A greedy algorithm works by making locally optimal choices at each step in the hope of finding a globally optimal solution. For the knapsack problem, the greedy approach sorts items by profit/weight ratio and fills the knapsack accordingly. For activity selection, it schedules activities based on earliest finish time. For job sequencing, it sorts jobs by profit and schedules the most profitable jobs that meet deadlines.
Divide and conquer
The document discusses divide and conquer algorithms. It describes divide and conquer as a design strategy that involves dividing a problem into smaller subproblems, solving the subproblems recursively, and combining the solutions. It provides examples of divide and conquer algorithms like merge sort, quicksort, and binary search. Merge sort works by recursively sorting halves of an array until it is fully sorted. Quicksort selects a pivot element and partitions the array into subarrays of smaller and larger elements, recursively sorting the subarrays. Binary search recursively searches half-intervals of a sorted array to find a target value.
Branch and bound
The branch-and-bound method is used to solve optimization problems by traversing a state space tree. It computes a bound at each node to determine if the node is promising. Better approaches traverse nodes breadth-first and choose the most promising node using a bounding heuristic. The traveling salesperson problem is solved using branch-and-bound by finding an initial tour, defining a bounding heuristic as the actual cost plus minimum remaining cost, and expanding promising nodes in best-first order until finding the minimal tour.
Asymptotic notation
This document discusses asymptotic notations that are used to characterize an algorithm's efficiency. It introduces Big-Oh, Big-Omega, and Theta notations. Big-Oh gives an upper bound on running time. Big-Omega gives a lower bound. Theta gives both upper and lower bounds, representing an algorithm's exact running time. Examples are provided for each notation. Time complexity is also introduced, which describes how the time to solve a problem changes with problem size. Worst-case time analysis provides an upper bound on runtime.
String matching algorithms
This document discusses and defines four common algorithms for string matching:
1. The naive algorithm compares characters one by one with a time complexity of O(MN).
2. The Knuth-Morris-Pratt (KMP) algorithm uses pattern preprocessing to skip previously checked characters, achieving linear time complexity of O(N+M).
3. The Boyer-Moore (BM) algorithm matches strings from right to left and uses pattern preprocessing tables to skip more characters than KMP, with sublinear worst-case time complexity of O(N/M).
4. The Rabin-Karp (RK) algorithm uses hashing techniques to find matches in text substrings, with time complexity of
Transport Layer
The document provides an overview of several transport layer protocols and concepts:
- TCP is a connection-oriented protocol that provides reliable, ordered delivery through the use of acknowledgments, flow control, and error control. UDP is a simpler connectionless protocol.
- Sockets provide an interface between applications and the network, allowing applications to build distributed client-server systems.
- Congestion control is important to prevent network congestion and ensure fair resource sharing between flows. TCP uses end-to-end congestion control while some protocols use network feedback.
- RTP and RTCP are used for real-time media delivery over UDP, providing sequencing, timing information, and quality monitoring without guarantees.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

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.
