In a heterogeneous wireless network, multiple networks are available to provide seamless connectivity. In this environment, the terminal has the ability to connect to most efficient network as per users requirements. This is known as network selection. This selection is done by assigning weightage to network attributes on the basis of users preference. In(More)
Wireless Sensor Network platforms are less expensive and more powerful having tiny electronic devices called Motes (sensor nodes). Wireless sensor networks enhance its popularity in military and health centric research areas; now it is also popular in industrial area. This paper describes the security requirements as WSNs are easily prone to more attacks(More)
An optimum DFT-modulated filter bank with sharp transition band as a non-linear optimization has been formulated .The design of this filter is very expensive by the standard method ,and hence the frequency response masking(FRM) technique is developed so as to reduce the complexity in the design process. An effective approach is proposed to solve this(More)
Interest in adaptive filters endures to produce as they onset to find useful real-time requests in spans such as channel equalization, echo cancellation, sound cancellation and countless supplementary adaptive gesture processing applications. The key to prosperous adaptive gesture processing understands the frank properties of adaptive algorithms such as(More)
In the presence of heterogeneous wireless network the selection of optimal network for transferring data and telephony is an important task. The selection of optimal network is done either at user terminal or at service provider terminal or at both terminals. This selection is done by some advancement in the mobile terminal. Therefore, the main challenge in(More)
