Flying ad-hoc network (FANET) is a special class of MANET that provides the communication among small flying drone called UAVs (unmanned aerial vehicle) enable with camera, sensor and communication system. FANET has wide area of applications like reconnaissance and surveillance for military and civil purposes. FANETs along with its special features have several challenges and issues those need to be considered. Routing in FANETs is one such issue because all the information exchanging process is done by the Routing protocol. In this experiment, the performance of OLSR and AODV routing protocols are analyzed for 3 D FANET environment by utilizing Gauss Markov Mobility Model. We have investigated the performance of protocols by varying group of UAVs and number of packets. Gauss Markov Mobility model has been used to produced 3 D cube area with dimension 1700x1700x1500 me...

With a widespread growth of the applications of WSN, the security mechanisms are also be a rising big issue. A lot of realworld applications have been already deployed and many of them will be based on wireless sensor networks. These applications include geographical monitoring, medical care, manufacturing, transportation, military operations, environmental monitoring, industrial machine monitoring, and surveillance systems. This paper discusses typical constraints, security goals, threat models and typical attacks on sensor networks and their defensive techniques or countermeasures relevant to the sensor networks, including security methods. The most critical area prone to attack is nearby the base station as the data is more aggregated, that should be kept secure using a number of defensive techniques as stated.

Recent worm and virus incidents such as Code Red, Nimda, and the Slammer worm have heightened security awareness. Also, numerous other threats have emerged recently that are particularly troublesome. Hence some solution must be provided to encounter the new generation of complex threats. Building up this solution requires the Integration of different security devices. Also system administrators, under the burden of rapidly increasing network activity, need the ability to rapidly understand what is happening on their networks. Hence Correlation of security events provide Security Engineers a better understanding of what is happening for enhanced security situational awareness. Visualization leverages human cognitive abilities and promotes quick mental connections between events that otherwise may be obscured in the volume of IDS alert messages. Keeping all these points i...

Because wireless sensor nodes are limited i n computing power, data storage and communication capabilities, any user authentication protocol must be designed to operate efficiently in a resource constrained en vironment. With a widespread growth in the potential applicati ons of WSN, the need for reliable security mechanisms for them has increased manifold. Security protocols in WSNs, unlike the traditional mechanisms, need special efforts and is sues to be addressed. The set of challenges in sensor networks are diverse, we focus on attacks on Wireless Sensor Net work in this paper.

Many applications were solved by such algorithms and are replacing the traditional classical optimization processes. A recent naked mole-rat algorithm (NMRA) was proposed based on the mating patterns of naked mole-rats. This algorithm proved its worth in terms of competitiveness and application to various domains of research. The aim was to propose an algorithm based on NMRA, named enhanced NMRA (ENMRA), by mitigating the problems that this algorithm suffers from: slow convergence, poor exploration, and local optima stagnation. To enhance the exploration capabilities of basic NMRA, grey wolf optimization (GWO)-based search equations were employed. Exploitation was improved using population division methods based on local neighborhood search (LNS) and differential evolution (DE) equations. To avoid the local stagnation problem, a neighborho...

Apart from these two problems, m-ACO has been experimentally evaluated using open source software JFreeChart. Methods: m-ACO finds the optimized solution to test suite prioritization by modifying the phenomenon used by natural ants to reach to its food source and select the food. This paper attempts to experimentally and comparatively evaluate the proposed m-ACO technique for test case prioritization against some contemporary meta-heuristic techniques using two well known software testing problems and open source problem. Performance evaluation has been measured using two metrics namely APFD (Average Percentage of Faults Detected) and PTR (Percentage of Test Suite Required for Complete Fault Coverage). Findings: The proposed technique m-ACO proves its efficiency on both the parameters. m-ACO achieves higher fault detection rate with minimized test suite as comparative to other meta-heuristic techniques for test case prioritization. Improvements: The proposed technique m-ACO basically works by modifying the food source searching and selection pattern of the real ants. Real ants grab every type food source it comes across; while modified ants evaluate the food fitness and uniqueness before selection. This phenomenon enhances the quality and diversity of deposited food source.

Frequent path breaking, multihop wireless link between mobile nodes, self organization and maintenance are such properties that makes difficult to provide trust in MANET. This paper proposes the new trust scheme, which provides malicious free atmosphere for mobile ad-hoc network. This model first check the authenticity of nodes through challenge response method and then PKI certificate will be given to only authenticated nodes so as to enable the trusted communication platform. At last this paper give the comparisons of ACTP model with other existing trust model.

This characteristic makes more MANET more vulnerable to attacks especially routing based attacked. There is a need for investigating the performance of attacks with respect to mobility. In this paper, we have investigated blackhole node attack in mobile adhoc networks. Blackhole node attack is the attack in which all traffic is redirected to a specific node, which may not forward any traffic to all other nodes. Here the test-bed is created and developed the system using AODV as a base routing protocol on the network simulator. Various network performance parameters i.e. throughput, packet delivery ratio, collisions etc. are analyzed before and after attack. On implementation of blackhole node attack the performance of the network reduces, on increasing mobility the performance of MANETs decreases sharply i.e. PDR decreases sharply, Number of collisions increases and Energy consumption increases in significance amount.
