Laxmi Shrivastava,Sarita Singh Bhadouria,Amit kumar 보안공학연구지원센터 2015 International Journal of u- and e- Service, Scienc Vol.8 No.6
The Rectenna consisting of Radio Frequency to Direct Current conversion circuit with antenna for the reception of RF signal needs to be designed to realize efficient power transmission with high conversion efficiency. In this paper, main area of work is to design Rectenna using low pass filter circuit with different order of filters. The parameters of the complete system have been calculated by using Matlab. Simulated results using CST have been compared and analyzed for different orders of filters.
A Critical Analysis of Congestion Adaptive Routing Protocols for Mobile Ad-Hoc Networks
Laxmi Shrivastava,G. S. Tomar 보안공학연구지원센터 2016 International Journal of Future Generation Communi Vol.9 No.6
Congestion in mobile ad hoc networks leads to transmission delays and packet losses and causes wastage of time and energy on recovery. In the current designs, routing is not congestion adaptive. Routing may let a congestion happen which is detected by congestion control, but dealing with congestion in this reactive manner results in longer delay and unnecessary packet loss and requires significant overhead if a new route is needed. This problem becomes more visible especially in large-scale transmission of heavy traffic such as multimedia data, where congestion is more probable and the negative impact of packet loss on the service quality is of more significance. Routing should not only be aware of, but also be adaptive to, network congestion. Routing protocols which are adaptive to the congestion status of a mobile ad hoc network can greatly improve the network performance. Many protocols which are congestion aware and congestion adaptive have been proposed. In this paper, we present a survey of congestion adaptive routing protocols for mobile ad hoc networks.

The characteristic of changing topology without a fixed infrastructure and lacking of any centralization is mobile adhoc networking (MANET).The communication between mobile nodes uses multihop wireless links. In the network; nodes act as router and forwarding data packets to other nodes behaving as intermediate node. Routing protocols plays an important role to facilitate communication within the network. In this paper we have compared different transmission power by varying antenna height. Simulation results shown in AODV routing protocol in term of the metrics: Throughput, Average end to end delay, Average jitter. The results are showing various changes due to change in the selected parameters, which are performance parameters of the network.

The collection of the many mobile nodes forming a short lived infrastructure with the help of any centralized administration. Since there's a random and dynamic modification in topology due to the quality of host, so the requirement for a study dynamic routing protocol is needed. Mobile ad-hoc network have the attributes like wireless affiliation, continuously dynamic topology, distributed operation and simple deployment. It establishes a short lived affiliation wherever nodes will be part of or leave the network at any time. Communication takes place by routing protocols in effective and economical manner in wireless network. Economical protocols are accustomed forward information packets while not a lot of packet loss. The target of the present paper is to boost the performance of the reactive and hybrid routing protocols with different directional antenna i.e. Omni and Pattern antenna. The performance metrics in the research paper is PDR, NRL, Throughput and Routing Overhead.

Nodes Are Connected By A Wireless Channel. There Are Need Of Routing Protocols For Communication In Such Networks. The Work Of Routing Protocol Is Efficient And Timely Delivery of Message. MANET Offers Versatility for Certain Environments and Certain Applications. In This Paper The Comparison of AODV And DSR Has Analyzed At Different Transmission Power.
Performance Evaluation of AODV Using Fuzzy Logic to Reduce Congestion in MANET
Vikas Thakur,Laxmi Shrivastava,Sarita S.Bhadauria 사단법인 인문사회과학기술융합학회 2015 예술인문사회융합멀티미디어논문지 Vol.5 No.5
Mobile ad-hoc network is an infrastructure less network as it doesn’t follow any particular network topology. In MANET congestion is a major problem in small size networks congestion’s effect is low as compared to the large size networks. Congestion degrades the performance of overall network drastically. Many algorithms have been proposed to handle the congestion famous one are the active que management algorithms (AQMs). But still there is no universally accepted solution for it. In this paper a congestion control solution is devised using fuzzy logic controller. In this node density and load are taken as input and packet drop probability as output, which is effective to control congestion in large networks.
Performance Evaluation of Two Reactive Routing Protocols for RWP Mobility Model with Different Speed
Neelam Singh,Laxmi Shrivastava 보안공학연구지원센터 2015 International Journal of Future Generation Communi Vol.8 No.5
Wireless adhoc network are self creating self organizing and self administrating. The nodes within the network are free to move thus network do not rely on the preexisting infrastructure. Due to ease in deployment of mobile adhoc network wireless network are widely used. In the wireless network topology continuously changes according to the data packets to be sent at the destination path. With this so many best results in the wireless communication in this era wireless network over took wired network. In this paper we have compared the performance of two reactive MANET routing protocols AODV and DSR by using random way point mobility model. Both share similar On-Demand behavior, but the protocol's internal mechanism leads to significant performance difference. We have analyzed the performance of protocols by network load, mobility model and type of traffic (CBR). A detailed simulation has been carried out in QUALNET 6.1. The metrics used for performance analysis are Throughput, Average end-to-end Delay and Average jitter.

In today’s world, nothing seems to be impossible, due to the astonishing advancements in science and technology. Now days, many humans are dependent on internet for their daily chores. But, congestion is one of the major issues, which affects the performance of such data networks. Thus, in order to control congestion, various schemes have been developed. In this research paper, the active queue management (AQM) scheme i.e. random early detection (RED) AQM algorithm is modified using fuzzy logic MATLAB tool, in such a manner that the efficient and reliable performance of the network can be maintained and improved as well. The results are verified with the help of QualNet 6.1 network simulator.
