In mobile distributed networks, there may be possibility of unreliable communications and lack of flexibility in storing the data. In this paper, authors have proposed a distributed-based caching technique and error-free communication in mobile distributed networks. For every mobile host of the multicast tree, a mobile is placed to monitor the failure and to initiate failure recovery technique. Then the data storage is performed by selecting the caching policy based on game theory. The simulation result shows that this proposed technique enhances the reliability and reduces the communication failures. © Springer Science+Business Media Singapore 2017.

Vehicle to Vehicle communication is comes under ehicular ad-hoc network (VANET). VANET uses the concept of mobile ad-hoc network. VANET gives flexibility to communicate between high speeds vehicles and create a network. VANET classification is done in three different category such as Vehicle to Infrastructure (V2I), Vehicle to Vehicle (V2V) and Hybrid network which is a combination of V2V and V2I network. VANET can be very effective in road safety communication, at the time of network congestion or entertainment purpose. But as services is increases QoS providing to the end user is a challenging task for service provider because of wireless medium and nature of node (vehicle ) is mobile with very high speed. The existing protocol proposed till today's date does not consider network initialization advertisement, periodic beaconing factor which are necessary to provide effective V2V. Due to which the broadcasted packets are neither acknowledged nor it is retransmitted which in turn increases the frame loss due to channel error. To cater this in work the author propose an Adaptive Medium Access Control (AMAC) Scheduler for prioritized multi-channel Dedicated Short Range Communication (DSRC) based V2V communication in IEEE 802.11pMAC protocol. The simulation is conducted for collision, packet transmission and throughput efficiency for varied vehicle. The experimental result shows the proposed AMAC scheduler, performs better than existing Non Cooperative Cognitive Multiple Access (NCCMA) in term of collision, successful packet transmission and throughput efficiency for varied no. of vehicle and thus helps improving QoS for DSRC based V2V communication for different application like safety and non-safety related application. © 2016 IEEE.

An enhanced and robust transreceiver model is proposed here which controls the power consumption dynamically and improve overall sumrate over k-client MIMO scenario. In order to reduce the interference, pairing system among transmitter and receiver is proposed in such a way that local optimal point matches the most, the communication will established at that point only. Every information stream is encoded at a various data rate, though diverse streams can be encoded at different rates. We assume that the transmitter or local channel data could be obtained by that very transmitter terminal. We propose an enhancement approach to improvise sumrate overall, power control and transceiver architecture. The beamforming technique is incorporated at transmitter side and at the receiver end antennas are incorporated with different angels to amplify the signal in a better way. By this technique signal to noise ration could be improved and at the same time power consumption is minimized. Experimental evaluation shows that the result accomplished with proposed method is having better performance when compared to other existing techniques in MIMO/OFDM system. © 2016 IEEE.

The emergence of the Smart Transportation System (STS) has given new way to think and give number of benefits to the transportation industry. Vehicular Ad-hoc Network (VANET) is a conception like MANET (Mobile ad-hoc network) but in VANET moving vehicle inter connected and communicate with each other wirelessly. Wireless communication technologies play a very important role in both type of communication Vehicle to Infrastructure (V2I) and Vehicle to Vehicle (V2V) in VANET. The existing model suffers from throughput efficiency due to improper channel modeling which does not consider environmental factor. To cater this in this work the author proposed an environmental model for varied scenario such as City, Expressway and Village (CER) to sturdy the impact of throughput performance and packet drop considering environmental factor for DSRC based V2V communication in IEEE 802.11p mac protocol. The experiment result conducted shows the effectiveness of throughput and collision for varied environmental model. © 2016 IEEE.

The combined effect of magnetic field dependent (MFD) viscosity and a local thermal non-equilibrium (LTNE) on the criterion for the onset of ferromagnetic convection in a ferrofluid saturated horizontal porous layer heated from below in the presence of a uniform vertical magnetic field is studied analytically using linear stability theory. A modified Darcy equation is used to describe the flow in the porous medium and a two-field model for temperature each representing the solid as well as fluid phases separately is used for energy equation. It is demonstrated that the principle of exchange of stability is valid. The results indicate that the onset of ferromagnetic convection is delayed with an increase in the MFD viscosity parameter but shows no influence on the critical wave number. Moreover, the system is found to be more stable when the magnetic forces alone are present. Asymptotic solutions for both small and large values of scaled interphase heat transfer coefficient Ht are presented and compared with those computed numerically. An excellent agreement is obtained between the asymptotic and the numerical results. Besides, the influence of magnetic and LTNE parameters on the stability characteristics of the system is also discussed. © 2011 Elsevier Ltd. All rights reserved.

Network is growing day by day. New devices are getting added into the network making it very difficult for an IT administrator to configure the ACLs and the other network parameters in the devices. Flexibility and programmability are the key factors in the present day scenario. Software Defined Networks (SDN) is the evolving network technology which provides the two factors mentioned. The latency in the packet delivery is less compared to the legacy Hardware Defined Networks (HDN) and in turn the throughput is also high. The work done in this paper provides a Proof of Concept (POC) for the better throughput of SDN-based routing. © Springer India 2016.

Due to explosive growth of traffic volume, it is hard to accumulate Internet traffic on a single machine. In this paper, a Hadoop-based traffic analysis system accepts input from multiple data traces. Hadoop facilitates scalable data processing and storage services on a distributed computing system. This system accepts input of large scales of trace file generated from traffic measurement tool like Wireshark– identifies flows running on the network from this trace file. Characteristics of flow describe the pattern of network traffic; it helps network operator understand network capacity planning, traffic engineering, and fault handling. The main objective is to design and implement a traffic flow identification system using Hadoop. The traffic flow identification system will be very useful for network administrator to monitor faults and also to plan for the future. © Springer India 2016.

Wireless Sensor Networks (WSNs) consist of small nodes with sensing, computation and wireless communications capabilities. These sensor networks interconnect a several other nodes when established in large and this opens up several technical challenges and immense application possibilities. These wireless sensor networks communicate using multi-hop wireless communications, regular ad hoc routing techniques cannot be directly applied to sensor networks domain due to the limited processing power and the finite power available to each sensor nodes hence recent advances in wireless sensor networks have developed many protocols depending on the application and network architecture and are specifically designed for sensor networks where energy awareness is an essential consideration. This paper surveys recent routing protocols for sensor networks and compares the routing protocols that are presently of increasing importance. Here three main categories of protocols, flat based, hierarchical and location based protocols are distinguished based on the way the next hop is selected on the route of a message and briefly describes the operation of a representative member from each group. Each routing protocol is described and discussed under the appropriate category. We also highlight the advantages and performance issues of each routing technique. The paper concludes with possible future research areas. © 2011 IEEE.

Measurement is fundamental to any engineering discipline. There is considerable evidence that object oriented design metrics can be used to make quality management decisions. This paper focuses on an empirical evaluation of object oriented metrics proposed by Chidamber and Kemerer across the two languages. Three projects in Java and two projects in C++ have been considered as input for the study. The resulting values have been analyzed to provide significant insight about the object oriented characteristics of the projects. © 2011 Springer-Verlag Berlin Heidelberg.

Metrics have been used to measure many attributes of software. For object oriented software, cohesion indicates the level of binding of the class elements. A class with high cohesion is one of the desirable properties of a good object oriented design. A highly cohesive class is less prone to faults and is easy to develop and maintain. Several object oriented cohesion metrics have been proposed in the literature. These metrics have provided a lot of valuable insight into the mechanism of cohesion and how best to capture it. However they do suffer from certain criticisms. In this paper, we propose a new cohesion metric named as High Precision Cohesion Metric (HPCM). HPCM addresses the drawbacks present in the existing cohesion metrics. We introduce two novel concepts - link strength and average attributes used in a class and apply them to arrive at the proposed metric. The metric is presented using the unified cohesion framework to avoid ambiguity. The metric is validated using theoretical approach suggested in the unified framework for cohesion metrics. Empirical validation is also carried out on this metric using data from open source Java projects. The newly proposed High Precision Cohesion Metric overcomes the shortfalls of the earlier proposed cohesion metrics.
