A Wireless Sensor Network (WSN) is a wireless network consisting of small sensor nodes. Sensors are used to monitor physical or environmental conditions. WSNs are particularly used in military and civilian applications. As WSNs are generally deployed in an unattended area, they are prone to various types of attacks. One of the harmful attacks is Sybil attack in which a node illegitimately claims multiple...
A Wireless Sensor Network (WSN) is a wireless network which contains small sensor nodes to monitor physical or environmental conditions. When WSNs are deployed in inaccessible areas, the probability of occurring different types of attacks is very high. So the security of WSN becomes extremely important. As sensors have limited processing power, limited storage, low bandwidth, and energy; traditional...
In this growing world, widespread and easily available use of mobile and portable devices such as, laptops, PDAs etc., the mobile ad hoc networks are receiving more attention for connectivity between these devices in real time. Ant Colony optimization routing is an adaptive and efficient for MANETs. Now a days, routing in mobile ad hoc networks (MANETs) is a very challenging and growing issue because...
Wireless Sensor Networks (WSNs) are most growing research area because of its low cost, infrastructure less, increase capabilities of nodes, real time and accurate. Localization is a major issue in the wireless sensor networks because it has a number of sensor nodes which are deployed at positions and they may not be fixed at their own position. In localization different techniques are used for distance...
A video texture is nothing but a continuous, infinitely varying stream of video images. It is a sequence of images with visual pattern repetition in spatial and time domain, like river flow, smoke, fire, clouds, water fall, and windy grass field etc. The simplest way of producing a video texture is to synthesize it from a finite set of images by randomly rearranging (and possibly blending) original...
