Fog Computing
The term “fog computing” or “edge computing” means that rather than hosting and working from a centralized cloud, fog systems operate on network ends. It is a term for placing some processes and resources at the edge of the cloud, instead of establishing channels for cloud storage and utilization.
wireless sensor networks & application :forest fire detection
With the advancements in wireless technology and digital electronics, some tiny devices have started to be used in numerous areas in daily life. These devices are capable of sensing, computation and communicating. They are generally composed of low power radios, several smart sensors and embedded CPUs (Central Processing Units). These devices are used to form wireless sensor network (WSN) which is necessary to provide sensing services and to monitor environmental conditions. In parallel to WSNs, the idea of internet of things (IoT) is developed where IoT can be defined as an interconnection between identifiable devices within the internet connection in sensing and monitoring processes. This paper presents detailed overview of WSNs. It also assesses the technology and characteristics of WSNs. Moreover, it provides a review of WSN applications and IoT applications.

2.INTRODUCTION
Android is a Linux-based operating system designed primarily for touchscreen mobile devices such as smartphones and tablet computers.
Initially developed by Android, Inc., which Google backed financially and later bought in 2005, Android was unveiled in 2007 along with the founding of the Open Handset Alliance: a consortium of hardware, software, and telecommunication companies devoted to advancing open standards for mobile devices. The first Android-powered phone was sold in October 2008.
3.ARCHITECTURE
4.Android consists of a kernel based on Linux kernel version 2.6 and, from Android 4.0 Ice Cream Sandwich onwards, version 3.x, with middleware, libraries and APIs written in C, and application software running on an application framework which includes Java-compatible libraries based on Apache Harmony.
Android uses the Dalvik virtual machine with just-in-time compilation to run Dalvik 'dex-code' (Dalvik Executable), which is usually translated from Java bytecode.The main hardware platform for Android is the ARM architecture.
5.APPLICATIONS
Android has a growing selection of third party applications, which can be acquired by users either through an app store such as Google Play or the Amazon Appstore, or by downloading and installing the application's APK file from a third-party site.
The Play Store application allows users to browse, download and update apps published by Google and third-party developers, and is pre-installed on devices that comply with Google's compatibility requirements.
6.APPLICATIONS
The app filters the list of available applications to those that are compatible with the user's device, and developers may restrict their applications to particular carriers or countries for business reasons. Purchases of unwanted applications can be refunded within 15 minutes of the time of download, and some carriers offer direct carrier billing for Google Play application purchases, where the cost of the application is added to the user's monthly bill.
As of September 2012, there were more than 675,000 apps available for Android, and the estimated number of applications downloaded from the Play Store was 25 billion.
7.SECURITY & PRIVACY
Android applications run in a sandbox, an isolated area of the system that does not have access to the rest of the system's resources, unless access permissions are explicitly granted by the user when the application is installed. Before installing an application, the Play Store displays all required permissions: a game may need to enable vibration or save data to an SD card, for example, but should not need to read SMS messages or access the phonebook. After reviewing these permissions, the user can choose to accept or refuse them, installing the application only if they accept.

ABSTRACT
Cloud computing promises to significantly change the way we use computers and access and store our personal and business information. With these new computing and communications paradigms arise new data security challenges. Existing data protection mechanisms such as encryption have failed in preventing data theft attacks, especially those perpetrated by an insider to the cloud provider. For securing user data from such attacks a new paradigm called fog computing can be used. Fog Computing is a paradigm that extends Cloud computing and services to the edge of the network. Similar to Cloud, Fog provides data, compute, storage, and application services to end-users. The motivation of Fog computing lies in a series of real scenarios, such as Smart Grid, smart traffic lights in vehicular networks and software defined network .This technique can monitor the user activity to identify the legitimacy and prevent from any unauthorized user access. Here we have discussed this paradigm for preventing misuse of user data and securing information.

Google cloud messaging
Google Cloud Messaging (GCM) allows Android developers to send data from servers to their apps and receive messages from apps to servers. It uses lightweight messages up to 4kb that are authenticated. Third party servers can send messages to Android apps registered with the Google Cloud Server. GCM supports sending single messages to multiple devices simultaneously. Setting up GCM requires configuring the Android app, third party application server, and Google Cloud Server which handles message delivery between the other two.
google cloud messaging
Google Cloud Messaging (GCM) is a service that allows servers to send messages to Android applications. It is a replacement for an older service called C2DM that had limitations. GCM handles message delivery more efficiently by using existing Google services and allows for features like message multicasting to multiple devices, multiple senders, messages with payloads, and setting time to live for messages. Developers can use GCM to more easily send various types of messages and updates to Android applications from their servers without frequent syncing.

secure data retrieval for decentralized disruption-tolerant military networks
The document proposes a secure data retrieval scheme using ciphertext-policy attribute-based encryption (CP-ABE) for decentralized disruption-tolerant military networks. Existing CP-ABE schemes have challenges including attribute revocation, key escrow, and coordination of attributes from different authorities. The proposed scheme addresses these by enabling immediate attribute revocation, defining access policies over attributes from multiple authorities, and resolving the key escrow problem through an escrow-free key issuing protocol. This allows encryptors to define access policies and securely share encrypted data in disruption-tolerant military networks.

GCM Technology for Android
This document provides an overview of push notification technologies poll and push, C2DM, and GCM. It discusses how poll notifications require devices to periodically check for new data, increasing network usage and reducing battery life, while push notifications allow servers to push new messages to devices. C2DM was retired and replaced by GCM, which allows application servers to send push messages to Android apps through Google servers. The document also outlines the basic components and process of how GCM works to deliver push notifications from servers to Android applications and devices.
GCM Android
Google Cloud Messaging (GCM) is a service that allows servers to send messages to Android devices. It handles message delivery and requires minimal battery consumption compared to regular polling. To use GCM, an Android app registers with the GCM server to receive a registration ID and the server sends messages addressed to that ID. When a device receives a message, the GCM service passes the data to the Android app via a intent. GCM supports unlimited messaging at no cost.
GCM with Pushbots
GCM stands for Google Cloud Messaging .
It is a free service that allows developers to send data from third party servers to their applications running on android devices.
Magda badita gcm
GCM (Google Cloud Messaging) is a free service that allows application servers to send lightweight messages to Android applications. It eliminates the need for continuous polling of a server for updates by allowing messages to be pushed to devices even when apps are not running. Developers must integrate the GCM client library into their Android apps, register their apps with the Google API console to obtain an API key, and handle incoming messages with a GCMIntentService. The GCM service replaces the deprecated C2DM service with easier setup and no quotas on messages.

GOOGLE CLOUD MESSAGING PPT 2017
ABSTRACT:-
Today Android is widely used operating system for smart phones, it is used as personal computer also. It contains a touch screen user interface, camera and network monitoring. The main purpose of this paper is to proposed a methodology to provide instant messaging over Google Cloud Messaging (GCM) and also we presents a survey on timing performance of GCM, our findings that the message delivery is uncertain , it does not guarantee to timely message arrival. Therefore is not applicable for time sensitive, but it may be good for application scenarios where random multicasting is sufficient.
This paper will help to learn Android device to device messaging (Instant Messaging) using Google Cloud Messaging (GCM). Communication flow arises from an Android device and the message to be communicated will be sent to GCM application server. From that server the message will be transfer to the Google Cloud Messaging server with the Reg Id of the device to send the notification. Then this message will be sent to another Android device by the Google Cloud Messaging server as a notification. It allows developers to send push messages to android device from the server. Google Cloud Messaging is a popular service as a client/server communication solution for android platform .
Keywords : Instant messaging, GCM, Timing performance of GCM.

Push-Notification
This document discusses push notifications from an application server to mobile devices using Google Cloud Messaging (GCM). It begins by explaining the drawbacks of traditional pull technology for mobile apps and how push notifications can address these issues. Next, it describes the system architecture involving an application server, GCM server, and Android app. The application server sends push messages to GCM which are then delivered to subscribed devices even if the app is not actively running. The Android app receives push messages from GCM and can create calendar events with configurable notifications. This system allows third parties to efficiently send notifications to registered customers on their mobile devices.
GCM aperitivo Android
Google Cloud Messaging (GCM) is a service that allows sending of push notifications from servers to Android devices. It uses an ID received during registration to send notifications even if the app is not active. Notifications are delivered near real-time with low battery usage. GCM requires Android 2.2+, Google Play Services, and a Google account on older devices. Developers must register their app project, get an API key, and handle registration and receiving of notifications within their app.

Android C2DM Presentation at O'Reilly AndroidOpen Conference
This document discusses push notifications on Android using Google Cloud to Device Messaging (C2DM). It explains that polling for updates consumes more battery life than push notifications, which allow a server to push new data to a device. The key components needed for C2DM are an Android app, Google's C2DM server, and an application server. It also discusses using Google App Engine to build the application server.
Android push-applications-android
This document discusses push notifications for Android applications. It describes how polling frequently to check for updates can drain a device's battery. The Android Cloud to Device Messaging (C2DM) API makes it easy for applications to use push notifications instead of polling. With C2DM, servers can send lightweight messages to Android apps through Google's infrastructure. When a message is received, the app is notified through a broadcast intent and can update from the cloud without polling. The document provides an overview of registering apps for C2DM, sending messages from servers, and receiving them on Android devices.

Future work could explore improving location accuracy and integrating payment systems.
Gcm tutorial
Google Cloud Messaging (GCM) is a free service that allows server apps to send small payload messages to Android apps running on devices. It handles message queueing and delivery. To use GCM, an app must register with the GCM connection servers to receive a registration ID, then send that ID to the app's server. The server can then send messages addressed to that registration ID via HTTP requests to GCM servers, which will deliver messages to the target app as a broadcast intent even if the app is not actively running.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
