Performance Analysis of AODV, DSR and CGSR Routing Protocol in MANET based on Energy Consumption
Abstract: Mobile Ad-hoc networks (MANET) have gained lots of attention in researches in recentyears, especially in routing protocols due to their dynamic nature. There are number ofrouting protocols in MANET networks and performance of these routing protocolshave been evaluated focusing on metrics such as delay, packet delivery, routingoverhead, throughput. However, not much work has been done to evaluate energyaspect of these routing protocols. Design new energy efficient routing algorithms arebased on …

Flooding Techniques in Wireless Sensor Networks: A Review
Abstract: Intended for network-wide dissemination of commands, configurations and code binaries, flooding has been investigated extensively in wireless networks. However, little work has yet been done on low-duty-cycle wireless sensor networks in which nodes stay asleep most of time and wake up asynchronously. In this type of network, a broadcasting packet is rarely received by multiple nodes simultaneously, a unique constraining feature that makes existing solutions unsuitable. Combined with unreliable links, …

A Threshold Based Scheme to Detect Black Hole Attack in DTN
Abstract: Security in DTN is a challenging task. Numbers of misbehaving attacks are present in the network. In this paper we focus on Black Hole attack with the problem of misbehaving and propose a solution based on the concept of threshold and validation. Each node maintains a local value called status of node. A node “status” is the delivery probability of nodes so doing, a misbehaving node is not chosen even …

A Reputation based Scheme to Detect a Black Hole Attack in MANET
Abstract: MANET is wireless network in which an end to end path is present between Network Security to MANET is wide problem. A black hole attack is an attack which drops the packets or provides wrong routing information to disturb routing process. In this paper we propose a new reputation based scheme to detect a black hole attack in MANET. In this scheme with the help of reputation of node we …

A Grade Based Scheme to Detect Malicious Nodes in Delay Tolerant Networks
Abstract: DTN is a network in which no direct contacts are present between network nodes. For data packet transmission in network, concept of intermediate nodes is used. Data transmission through intermediate nodes is not secure because unfortunately some intermediate nodes behave as malicious nodes. So security in DTN is a challenging task. Different types of malicious nodes perform different kind of attacks during data transmission. In this paper, present a grade …

A Comparative Analysis of Sleep Deprivation Attack in AODV
Abstract: Mobile ad-hoc networks (MANETs) are collection of wireless mobile computers (or nodes) having no pre-existing infrastructure or centralized management and which are connected by wireless links automatically. They are one of the most commonly used network services these days. They play a great role in tactical situations such as disaster relief or battlefields, making it an important area for research. But, unfortunately, the many factors that make MANETs successful (fluidity, …

Performance Analysis of Clustering Network Using Enhanced DEC Protocol for WSN
Abstract: Each node of a wireless sensor network (WSN) is connected to several other sensors. These sensor nodes can be deployed in dense for monitoring variety and wide range of applications. There are different types of protocols in WSN used to route the packets from source to destination. They are data-centric, hierarchical, and location-based and network flow and quality of service. To manage the energy consumption of WSN, one of the …

A Game Theory Approach to Enhance Routing and Security in MANET
Abstract: Mobile ad hoc network (MANET) is a collection of mobile nodes, which forms a temporary network without the aid of centralized administration. To create and maintain communication between nodes, the nodes dynamically establish paths among one another. The nature and structure of such networks makes it attractive to various types of attackers. Security in ad-hoc network is an essential component for basic network functions like packet forwarding and routing. These …

Detection and Prevention of Sybil Attack using Artificial Bee Colony Algorithm in Proximity of Closeness Centrality
Abstract: AbstractVehicular ad-hoc networks (VANETs) are the wireless network in which vehicles are equippedwith devices that communicates with each other via data packets. VANETs are mainlyadvocated for applications such as traffic collision detection, toll collection, controlling trafficcongestion, weather forecasting, road diversion warning, car maintenance etc. Security ofVANETs are vulnerable to various attacks such as Denial of Service (DoS), GPS spoofing,message alteration, black hole, wormhole attack, spamming attack, node impersonationattack, Sybil attack, …

Bandwidth Management in WSN Through Discrete Fourier Transform
Abstract: In wireless sensor network, bandwidth and energy is the major consideration. In WSN, there are various protocols and management techniques which are involved in the bandwidth utilization and minimization of energy used in the data communication. The most common problem in WSN is of traffic congestion which results in loss of packets hence wastage of bandwidth and energy used to transfer the data is also increased. The technique discussed in …

Implementation and Analysis of Internet Protocol TV Content Distribution Network Traffic Modeling in NS2
Abstract: Traffic analysis and modeling is an important approach to study network applications. In the past decade, numerous types of Internet and multimedia application traffic have been extensively studied and the result of this research shows that such traffic has the feature of self-similarity. Contrasted and these customary applications, IPTV has an alternate construction modeling and client practices. Thus, the attributes of IPTV movement vary from those of conventional applications and, …

Exploring Qualte-k-nology for a Breakthrough Tomorrow (Quality of, say, Particulate Technology Knowledge)
Abstract: Quality, knowledge and technology are synonyms which need the fourth wheel, of human intervention of an innovative mind. Technology-wise, the erstwhile powder metallurgy (PM) process evolved at the stance of lower heat and temperatures (call it energy) required for component development. With every increase in such costs, the PM components can only emerge as more competitive. From charting the past and future developments, this work attempts to journey through a …

Coordinated Checkpointing Algorithms: A Comparative Analysis
Abstract: In distributed system collection of independent computers appear to the users as a single computer. The property of fault tolerance is that it enables a system to continue operating properly if the failure occurs in the event of some of the components. Minimum process coordinated checkpointing is an appropriate approach to initiate fault tolerance in mobile distributed systems. Checkpoint-based rollback recovery restores the system state to the most recent reliable …
