A Mobile ad-Hoc Network is an anthology of nodes which is an infrastructure less network and hence can be easily established and deployed instantly. In addition to their normal operation, the entir...

Vehicular ad hoc Network (VANET) are a class of ad hoc systems work to guarantee the safety and security of traffic. An important point in VANET is the manner by which to believe the data transmitted when the neighboring vehicles are quickly changing and moving all through range. The fundamental point of this paper is to distinguish Sybil attack in VANET. A two phase security based mechanism is proposed to give reliable solution in identifying and blocking the Sybil attacked nodes to secure the information and providing safety and trust on the application. In the first phase Public Key Infrastructure (PKI) is taken and in the second phase hash function is considered. In this way to defeat Sybil attack we can easily recognizing Sybil attacks in VANET with much accurate.

Green building is a critical research zone in IoT. The energy productivity in green structures is a key for worldwide supportability. However, many elements influence energy utilization by the gadget and a large portion of the green structures are not by any stretch of the imagination green because of static energy supply and concentrated control on gadgets. Here, we propose a plan utilizing LEDs to influence utilization of dynamic energy to supply to build energy proficiency and circulated bunching of gadgets for shrewd programmed control.

There were many challenges existed in the area of MANET environment to do research and innovation. Some of the main areas are routing, data transfer, data acknowledgement, protocol implementation, multi casting, delay management and security etc. Efficient routing protocol is the backbone of MANET to achieve the scalability, reliability and security. Since last decade, many routing protocols and network topologies were introduced in MANETs to improve the efficiency. Earlier researches were concentrated on designing new protocols or updating the existing protocols to made MANET routing more efficient. Keeping in mind the end goal to address the issues in multicasting over MANETs, this theory proposed an Upgraded Scalable Virtual structures based Geographic Multicasting (USVGM) Protocol, which would extent be able to an expansive gathering size and substantial system size and this convention will give effective multicast parcel transmissions in a dynamic versatile specially appointed system condition. USVGM convention is actualized with the two layer design to dodge the participation administration problem. In this paper we propose USVGM prototcol which successfully handles the administration issues in MANETS.

Cloud Computing became an optimal solution for business customers to maintain and promote their business needs to clients via cloud services like IaaS, SaaS, and PaaS. On-Demand and pay-per-use scale up methodologies attracted organizations for cloud adoption and migration. Due to the increased demand for cloud services from users, Efficient Resource Management in cloud computing become an important task. In order to achieve resource multiplexing in cloud computing, recent researches were introduced dynamic resource allocation through virtual machines. Existing dynamic approaches followed un-evenness procedures to allocate the available resources based on current workload of systems. Unexpected demand for huge amount of resources in future may cause allocation failure or system hang problem. In this paper we present a new systematic approach to predict the future resource demands of cloud from past usage. This approach analyzes the resource allocation logs of virtual server, SLA agreements and follows the resource prediction algorithm to estimate future needs to avoid allocation failure problem in cloud resource management. Experimental results are supporting our strategy is more scalable and reliable than existing approaches.

Traditional communication networks can be leveraged by separating controlling functions from forwarding functions using emerging technology known as Software Defined Networking (SDN). Though SDN has been around for some years, it was mostly limited to wired networks. Of late, it is being adapted to wireless networks. The programmable interface with decoupled controller can be used with MANET to integrate with other networks besides controlling it well. Both control and security are inevitable for the successful implementation of SDN in wireless networks. Towards this end, in this paper we implemented SDN based MANET for secure routing. Open Flow is used for implementing SDN controller while IDC is used for securing communications. Our framework is evaluated with NS3 simulations that reveal significant performance improvement when compared with traditional ad hoc networks that do not use SDN. This is achieved as SDN controller can quickly adapt to changed topologies due to node mobility.
