The scheduling based DTCAR (Dynamic Traffic congestion-aware routing) algorithm is to schedule the data deliver and its send the data from source to destination is queue based approaches. S-DTCAR routing data from the jamming areas and increase the intense packets along with several paths consisting of inactive and below loaded nodes and   considered as the most promising talented wireless technologies that can considerably improve transmission capacity and dependability in wireless mesh networks. Our existing DTCAR also avoid the traffic but it’s differing from DTCAR this is a queue based on sending the packets from source to end of their wireless mesh network. S-DTCAR based this traffic congestion and reduces packet delay, loss and delivery ratio then improve network performance and to mostly reduce the delay of their data transmission. We have proposed to Q-SCHED of their network on best routing to choose and efficient data delivering from the source. Scheduling mostly used for to split the data and transmission speed level to be increased of the network it’s useful for transmit the data quickly to reach the destination.

In this paper we created a new routing fabric for reducing power and delay. The power consumed in a FPGA core consists of both static and dynamic components. Static power contributes only 10% of the total power consumed in a FPGA. On the other hand, dynamic power contributes over 90% of the total power consumed and it is the main source for their power inefficiency. By reducing net length and /or programming overhead the power consumption reduced. Routed net length reduced by using short intersects segments in the routing channels. By decreasing the switch box and / or connection box flexibilities programming overhead reduced. In this work ,we concentrated on achieving 1.80 times lower consumption of dynamic power  and 1.50  times less significant average net delays by re-architecting the programmable routing fabrics such that both routed net lengths and programming overhead reduced without adversely affecting delay.

This paper deals to assess the performance of the Pelton wheel turbine with different range of rotational speeds and varying loads using surface response methodology software Design Expert DX6 and their results achieved from the present investigation are discussed. The test results reveals that the predicted value and the observed value for turbine shaft rotation in rpm are indicating a very good fit for the response function equation. Similarly the predicted values and the observed values for discharge, input and output power are found same. It is also found that the predicted value [29.46%] and the experimental value [29.52%] are very good fit for the efficiency of Pelton turbine.
