In survivable optical networks, wavelength assignment is a major concern than assigning routes to the light path requests. Earlier wavelength assignment algorithm suffers from unbalanced utilization of wavelengths that leads to blocking probability for any connection request. This paper analyzes the performance of the wavelength assignment strategies to(More)
The paper proposes an effective Traffic surveillance system for detecting and tracking moving vehicles in nighttime traffic. It identifies vehicles by detecting and locating vehicle headlights and taillights using image segmentation and pattern analysis technique. By preprocessing noise is removed using median filter. Morphological operation is used to(More)
Discovering the malicious or vulnerable anchor node is an essential problem in wireless sensor networks (WSNs). In wireless sensor networks, anchor nodes are the nodes that know its current location. Neighbouring nodes or non-anchor nodes calculate its location coordinate (or location reference) with the help of anchor nodes. Ingenuous localization is not(More)
The goal of the project is to promote the use of multi-clouds and which has the ability to reduce risk in secure services. The existing system problems like service availability failure can be reduced by using multi-clouds. The proposed system involves the third party auditor(TPA) which includes, multi-cloud server, public auditing, batch auditing, data(More)
Malicious anchor nodes will constantly hinder genuine and appropriate localization. Discovering the malicious or vulnerable anchor node is an essential problem in Wireless Sensor Networks (WSNs). In wireless sensor networks, anchor nodes are the nodes that know its current location. Neighbouring nodes or non-anchor nodes calculate its location (or its(More)
OFDM/OQAM is preferred as multicarrier system which operates over a multipath channel. By using the multipath channel the signal-to-noise ratio. In earlier, sub carriers are used to transmit the signals. Nowadays, FFT and DFT are used for transmitting the signals based upon the bit values. AWGN is a channel used to identify the noise produced at the output(More)
The main idea is to collect data faster using a Wireless Sensor Networks which is organised in a tree form.Wireless Sensor Networks (WSNs) consists of numerous small sensors. These sensors are wirelessly connected to each other for performing same task collectively such as monitoring weather conditions or specifically parameters like temperature, pressure,(More)
Recently, there has been a rapid growth in the wireless communication technique. Mobile sinks can be mounted upon urban vehicles with fixed trajectories provide the ideal infrastructure to effectively retrieve sensory data from such isolated WSN fields. Existing approaches uses either single-hop transfer of data from SNs that lie within the MS's range or(More)
