Mobile Ad hoc NETwork (MANET) is a self-coordinated system which is intended through a group of mobile nodes with wireless links deprived of using any consolidated infrastructure. Communication between nodes occurs with the help of different routing protocol. The absence of centralized administration makes it vulnerable to various attacks. Worm hole attack is considered to ...

Wireless sensor network and its applications are intriguing research that has been concentrated as of late. Battery utilization of sensor nodes is the principle issue in the group of wireless sensor that ought to be sorted out. In this way, to expand the adaptability of the system, and to diminish the energy usage for general ...

Converge cast communication is used in many sensor applications. The flow of data in converge cast routing is from many to one i.e. many sensory nodes sense the data and send through parent child relation to the root node or sink node. Converge cast routing is always followed by broadcasting. In broadcast communication is from ...

Nodes in Mobile Ad hoc NETwork (MANET) are forming a dynamic topology by that the nodes are continuously change their location and also the nodes functioning is dependent on the limited battery capacity that is called energy. The dynamic behavior of network connection is not maintained for long time. All nodes in network are energy ...

MANET (Mobile Ad hoc NETwork) is an ad hoc network that can be formed on demand and allow nodes to communicate without any infrastructure. On demand set up of MANET makes it very popular as compared to the traditional wireless network. In traditional wireless network fixed point/central point is required for overall function of the ...

Antenna is one such device, which acts as both sensor and transducer that converts free space waves into electrical signal and vice versa. In the event there is a power failure the sensors will shut down a certain distribution system and restore power along an alternative route. To establish a direct line of sight high ...

Mobile Ad-hoc NETworks (MANETs) is self-organizing and self-configuring multichip wireless networks, where the structure of the network changes dynamically. This is mainly due to the mobility of the nodes. In static routing, the routes between the nodes are precomputed based on certain factors and are stored in routing table, all packets between any two nodes ...

In this paper, the authors investigate performance of a smart ESPAR (Electronically Steerable Passive Array Radiator) antenna with omni-directional and directional antennas. Performance of wireless network systems depends on the kind of antenna that is used. Every type of antenna has specific characteristics that determine gain, direction and bandwidth. Background of smart antennas has been ...

Smartphone has emerged as most popular gadget now-a-days offering most of functionalities of Personal computer as well as has developing features and applications based on internet, due to which smartphones become vulnerable to security threats similar to the personal computers. Smartphones have limited storage, computational power, processing so implementing intrusion detection and signature based attack ...

The booming demand in wireless communication system applications have caused microstrip patch antennas to attract much interest due to their light weight, comfortable to planar and non-planar surfaces, simple and inexpensive to manufacture using modern printed circuit technology, mechanically robust when mounted on rigid surfaces and when the particular patch shape and mode are selected, ...

A Mobile Ad-hoc NETwork (MANET) consists of wireless mobile nodes. The communication between these mobile nodes is carried out without any centralized control. MANET is a self-organized and self-configurable network where the mobile nodes move arbitrarily. The mobile nodes can receive and forward packets as a router. In this paper, the authors compared the performance ...

At actual, belabour handsets (reminiscent of resolution sensation) attack been hand-me-down far and dignified issues. Regardless, nearly the large-scale vicinity of the 0.33-stage changeable announcement methods and the manipulate development of eternal enlargement, the extremist LTE non-static terminals, exclusively for liquid ring up applications which grit be matter-of-definite factor publicly within the 3rd date and ...

In this paper, a novel double-printed trapezoidal patch dipole antenna compatible for UWB (Ultra-WideBand) functions with band-notched attribute is offered and investigated. The band-notched attribute is finished with the aid of inserting T-form slots on the trapezoidal radiating patches. The impedance characteristic, radiation patterns and the switch function are studied. Experimental results exhibit that the ...

A Mobile Ad-hoc NETwork (MANET) is a self-structure network of mobile routers connected by wireless link. The nodes are free to move randomly and independently. Ad-hoc networks suitable for emergency situations like natural or human made disasters, military conflicts, emergency medical situations etc. Major problem in a mobile ad-hoc network is constrains. In this paper, ...

In this paper, the authors introduce robust adaptive beamforming algorithm using novel antenna array geometry. The proposed array geometry consists of doubly crossed Uniform Linear Arrays (ULAs) which gives high accuracy beamforming and angular resolution as compared to conventional ULA. Furthermore, use of this geometry to adaptive beamforming algorithms namely LMS, NLMS and proposed Variable ...
