This paper considers theoretical issues regarding reconstruction errors and conditions for perfect reconstruction (PR) of the input signal for a 2-channel multirate quadrature mirror filter (QMF) bank. The main emphasis is on the application of genetic algorithms in the optimisation process of a new design technique for a perfect reconstruction QMF bank(More)
This paper considers theoretical issues concerning reconstruction errors and conditions for perfect reconstruction (PR) of the input signal for a 2-channel multirate quadrature mirror filter (QMF) bank. The main emphasis is on the optimisation of a new design of a perfect reconstruction QMF bank using infinite impulse response (IIR) filters based on(More)
WSNs plays an important role in many of the applications like patient health monitoring, battlefields surveillance, traffic control, environmental observation, home automation and building intrusion surveillance. WSNs are convenient, cost effective, and give ease of integration with other networks and their components. However, wireless technology also(More)
Transport layer protocols of Wireless sensor networks, plays an important role in the achievement of high performance and the long life time of the network. This layer is specifically needed when a system is organized to access other networks. Two functions provided by this layer are; reliability and the congestion control. Many numbers of protocols are(More)
Node localization in wireless sensor networks (WSNs) is one of the most important primary requisite that needs to be resolved efficiently as it plays a significant role in many applications namely environmental monitoring, routing and target tracking which is location dependent. Localization is defined as finding the physical co-ordinates of a group of(More)
