Low power fir filter using low power multiplier an
4.5
This paper presents the methods to reduce dynamic power consumption of a digital Finite Imppulse Respanse (FIR) filter these methods include low power serial multiplier and serial adder, combinational booth multiplier, shift/add multipliers, folding transformation in linear phase architecture and applied to fir filters to reduce power consumption due to this glitching is also reduced. The minimum power achieved is 110mw in fir filter based on shift/add multiplier in 100MHZ to 8taps and 8bits inputs and 8bits coefficients. The proposed FIR filters were synthesized implemented using Xilinx ISE Spartan 3E FPGA and power is analized using Xilinx XPower analyzer.

Energy efficient ROUTING PROTOCOLS FOR WSN
4.0
The typical routing protocol of wireless sensor network is Low Energy Adaptive Clustering Hierarchy (LEACH) protocol, which uses self organizing and dynamic cluster formation, so it has a problem that more or less cluster headers may have a bad effect on the network. This article will discuss that the quality of network can be optimized through controlling the number of cluster headers in LEACH protocol via the NS2 simulation, and then illustrate that setting optimal

Self organized tree based energy balance routing p
4.0
Modified Leach (low energy adaptive clustering hierarchy). We extend Leach's random cluster head selection algorithm by a deterministic component. Depending on the network configuration, it is possible to increase the lifetime of the network by about 30%. In addition, we propose a new method to define the lifetime of micro sensor networks using three new metrics: the national defense force (the first node mold), HNA (half of the nodes are alive) and lymphadenectomy (the last node mold).

Performance Evaluation of LTE Physical Layer Using
no vote
Since past few decades different types of cellular networks were launched and went successful on the radio links such as
WiMAX, that became very popular because of its high data rate (70Mbps) and support for providing wireless internet services
over 50km distance. The UMTS Long Term Evolution (LTE) is an emerging technology in the evolution of 3G cellular services.
LTE runs on an evolution of the existing UMTS infrastructure already used by over 80 percent of mobile subscribers globally.
We have very limited resources in cellular technologies and it is important to utilize them with high efficiency.
