In wireless sensor network, energy utilization is one of the most important parameter to be discussed. While doing communication, nodes are interconnected to create a network and sinks are placed on a board to carry the information to the base end also called sink. Maximum energy is being used for transmission of information. For increasing the lifetime of the network of WSN, we need to use lesser...
Today mobile ad-hoc network is become more popular and demanding in various applications such as emergency search operation, batter field areas etc. The reason is its economic configuration cost and infrastructure less characteristics. Additionally mobile ad-hoc network also has dynamic topology in which devices move frequently. Due to dynamic connectivity of nodes, routing operation require more...
Fountain Codes are referred to as a class of rateless codes'41 which efficaciously improves the performance of systems used for wireless data transmission. In this paper, we present a quantitative analysis of Fountain Coded Multiple Input Multiple Output (MIMO) — Orthogonal Frequency Division Multiplexing (OFDM) systems over Rician faded channel. Bit Error Rate (BER) performance evaluation and comparison...
Fountain Codes belongs to the class of rateless codes[4] which effectively improves the performance of systems used for wireless data transmission. In this paper, we present a quantitative analysis of Fountain Coded Orthogonal Frequency Division Multiplexing (OFDM) systems over Rician faded channel. Bit Error Rate (BER) performance evaluation and comparison is carried out for Fountain Coded and Convolution...
Software effort estimation requires high accuracy, but accurate estimations are difficult to achieve. Increasingly, datamining is used to improve an organization's software process quality, e.g. the accuracy of effort estimations. There are a large number of different method combination exists for software effort estimation, selecting the most suitable combination becomes the subject of research in...
