Title:An Improved Ad-Hoc Routing Protocol for MANETs using Swarm Intelligence Technique
Author Name:P. Sarika and V. V. Rama Prasad 
Synopsis:

Mobile ad-hoc networks (MANET) are formed by a group of mobile nodes and does not have any fixed infrastructure. Due to the node mobility nature in MANETs, different routing challenges such as, power constraints, link failures, and path breakages occur. Many routing protocols both proactive and reactive have been implemented to solve the routing challenges, but these protocols cannot defeat these issues in a complete manner. Researchers made an attempt to research on swarm intelligence based nature inspired algorithms to defeat the routing problems faced by the mobile ad-hoc networks. In the existing approach, BAT optimization which is a swarm intelligence technique was used to find the best path for Ad-hoc On-demand Multipath Distance Vector (AOMDV) protocol based on link availability and neighbour node queuing delay. But, this approach does not maintain a balanced control packet overhead. So, in this paper Bee Inspired routing Protocol (BeeIP) is proposed to provide multipath routing for mobile ad-hoc networks. BeeIP is a swarm intelligence based routing technique, which uses the honey bee forager behavior. Simulation results show that, the proposed approach BeeIP outperforms the BAT-AOMDV in terms of network performance metrics such as, packet delivery ratio, control overhead, average end to end delay.

Title:Drivers and Barriers to the Internet of Things
Author Name:Thomas Page
Synopsis:

The aim of this research is to investigate the development and implications for applications and future directions of the Internet of Things (IoT). The current understanding of the Internet of Things is explored and discussed to understand, what is currently understood because IoT has been often considered a vague and relatively little understood concept. A range of users were asked to describe their understanding of the IoT and how they use IoT devices. A significant finding showed that although the term Internet of Things has been known for several years and is becoming increasingly more widespread. However, there are privacy concerns with regards to the large amounts of personal data, transferred between IoT devices.

Title:Implementation of All-In-One Instant Messaging Application
Author Name:Dipti Pawade, Ajay Mohandas, Vijay Yadav, Rajankumar Bhimprasad and Pradeep Bagrao
Synopsis:

In today's world, Instant Messaging applications like Whats App, Line, Viber have increased the social interaction among people. The purpose of such application is to keep friends and families connected no matter how far they are. Now we can chat with our near and dear ones easily and can see them even if they are a million miles away. Some of the applications gives us the provision for sending images and videos to others or call them and this is all possible just by a single click on our handset. This type of applications are cheaper to use and also user friendly. In spite of advent of such applications, people are demanding for those applications that are efficient and can ease their work. Thus, the authors have planned to create an instant messaging application similar to WhatsApp along with some added features. Some of the features added are built-in AppLock, reminder notification, offline messaging, etc. The other notable features added are Integration of the application with other applications, and secure communication. The main goal of the paper is to develop an application which is user friendly and efficient to use.

Title:Performance Evaluation of DYMO and FSR in the Presence of Wormhole Attack over MANET
Author Name:M. Dhivyaa and K.R. Deepak
Synopsis:

Mobile Ad-hoc Network (MANET) consists of a collection of wireless mobile nodes that are capable of communicating with each other. MANETs are infrastructure-less, lack of centralized monitoring and dynamic changing network topology. So, this network is highly vulnerable to attacks due to the open medium. Wormhole attack is difficult to detect because they do not create any separate packets. In this paper, performance of wormhole attack is analyzed using DYMO and FSR routing protocol. The result analysis shows the impact of wormhole attack on MANETs in terms of throughput, average end-to-end delay, average jitter and packet delivery ratio.

Title:Mobile Data Collection with Secure Multihop Routing Protocol using Dual Data Upload Clustering in Wireless Sensor Networks
Author Name:K. Papithasri and M. Babu
Synopsis:

Wireless Sensor Networks have begun as an effective solution for a wide range of applications. Mobile data gathering is an important operation in sensor network. Most of the traditional sensor network architectures consist of static nodes that are deployed over a sensing area. However, a location service is considered, where each sensor essentials to maintain its location information by normally updating its location information within its neighboring set of polling points in the network. There is a moving path planning with multihop relay networks. The source node and the sink node communicate with each other either in single hop or multi-hop network. The existing approaches fail to deliver a guaranteed reliable network in terms of traffic, end-to-end connection and mobility. To overcome the problem of these failures, a Delay Aware Secure Multihop Routing (DASMR) protocol is proposed. In this protocol, sensor networks are first defined with mobile sink and then an overview of the data gathering process is presented in such a scenario based on the role of a mobile sink. Data can be gathered by its own or neighboring node by visiting each polling point through the cluster heads. Here, mobile data gathering is mainly focused on path selection problem. The node is travelled through the path, which is dynamically gathering the information at each cluster head. This DASMR scheme achieves over 70 percent of energy saving per node and 80 percent of energy saving on cluster heads comparing with previous works. Although, the number of polling points are also minimized by visiting the new polling points, which also extends the network lifetime. DASMR reduces the overall energy consumption and optimize the data collection tour to minimize the delay by the sink. Simulation experiments based on GloMoSim is shown to validate the high efficiency of the presented formulations and algorithms.

Title:Hybrid Enhanced Adaptive ACK IDS Scheme for MANETs
Author Name:S.B. Ninu and S. Behin Sam
Synopsis:

Mobile Adhoc Network (MANET) is one of the most important and unique applications. When compared to traditional network architecture, MANET does not require a fixed network infrastructure instead dynamic and distributed in nature; every single node act as both a transmitter and a receiver. In same communication range, the nodes communicate directly with each other. For outer range, they rely on their trust based neighbors to relay messages. In this case, it is crucial to develop efficient intrusion-detection mechanisms to protect MANET from attacks. In this paper, the authors propose and implement a new intrusion detection system named Hybrid Enhanced Adaptive Acknowledgment (HEAACK) specially designed for MANETs. They extend their work with the introduction of Hybrid Crypto systems to prevent the attacker from forging acknowledgment packets and reduce the network overhead which is caused by Digital Signature. In order to obtain the optimal AESs in MANETs, the authors have implemented DSA, RSA and AES schemes in the simulation. Eventually, they arose to a conclusion that the AES scheme is more suitable to be implemented in the MANETs. Simulation results show that the proposed Hybrid cryptosystem method is a more desirable scheme under MANETs.
