Spectrum Sensing over Rayleigh Fading in Mutihop Cooperative Networks
Abstract: This paper presents a novel cooperative spectrum sensing for the performance analysis of the multihop system model. In this paper, the performance of cooperative spectrum sensing is investigated through intensive simulation analysis by means of energy detection over Rayleigh fading distribution in multihop scenario. The closed form expressions for end-to-end SNR PDF of multihop networks over Rayleigh fading channels with different hard fusion methods are analyzed. Based on the framework …

Implementation of Floating Point Multiplier Using Dadda Algorithm
Abstract: Floating point multiplication is very useful in all the computation applications like in arithmetic operation, DSP application etc. To achieve higher speed of the mantissa, multiplication is done using Dadda multiplier which works on the basis of Dadda algorithm. Through this architecture we gain high speed with a maximum frequency and also reduce the number of gates compared to existing multipliers; and through floating point format it is possible to …

Base Station Based Clone Attack Detection & Prevention Technique in MANET
Abstract: Wireless sensor network (WSN) is a set of massive number of sensor nodes and its self configuring, multi hop network connection. Each node in the network communicates with another node if it lies within the transmission range. Each node acts as source and router in the sensor network. In WSN, security is key challenge due to different kinds of attacks i.e. node replication or clone attack. In wireless network, an …

Optimal Sensor Placement in Structures Using Improved Adaptive Genetic Algorithm with Modified Modal Assurance Criteria for SHM Systems
Abstract: With the growth of advanced constructive engineering technology, more and more large-scale structures, such as buildings, towers, wharfs, and so many other structures have been built all over the world. Due to uncontrolled environment, these civil infrastructures may be damaged severely by the natural disasters and the man made changes around the environment. To avoid this, monitoring of structure is necessary and it is done with the help of structural …

Sybil Defender: Defend Against Sybil Attacks in Networking
Abstract: Wireless sensor network is most popular now days in various places like defense, event sense, weather information and many more. Security is one of most concerning area for sensor network due to its infrastructure and flexibility to include other nodes in network. Sybil attack is the most sever attack in sensor network because in this attack, attacker node steals the identity of the node and then gets data of this …
