Qos Provisioning for Energy Efficiency in Mobile Ad-Hoc Network

In mobile ad-hoc networks Quality of Service QoS of a multicast routing protocol is one of the most key performance metrics Slotconditions and network topology frequently change Topology dynamic and in order to achieve a certain level of QoS complexalgorithms and protocols are needed Network graph conditionsare neglected during the design of aexisting multicast protocol However vulnerability against network graph errors can severely affect theperformance of a multicast protocol To address this here the author proposesanenergy efficient network graph pre-processing approach to enable traffic engineering and enhance the performance of energy efficiency in terms of network efficiency by QoSprovisioning to cater the multicast routing issue in MANETS In this approach prioritized admission control PAC scheme is implemented to improvise D2D Device to Device communications into cellular network to overcome the limitations of MANET

A Multirate MAC Protocol for Reliable Multicast in Multihop Wireless Networks

Many multicast applications, such as audio/video streaming, file sharing or emergency reporting, are becoming quite common in wireless mobile environment, through the widespread deployment of 802.11-based wirelessnetworks. However, despite the growing interest in the above applications, the current IEEE 802.11 standard does not offer any medium access control (MAC) layer support to the efficient and reliable provision of multicast services. It does not provide any MAC-layer recovery mechanism for unsuccessful multicast transmissions. Consequently, lost frames cannot be detected, hence retransmitted, causing a significant quality of service degradation. In addition, 802.11 multicast traffic is sent at the basic data rate, often resulting in severe throughput reduction. In this work, we address these issues by presenting areliablemulticastMACprotocol for wirelessmultihopnetworks, which is coupled with a lightweight rate adaptation scheme. Simulation results show that our schemes provide high packet delivery ratio and when compared with other state-of-the-art solutions, they also provide reduced control overhead and data delivery dela

A PROPOSED SOLUTION TO THE BOTTLENECK AND CAPACITY PROBLEM FOR DATA TRANSFER

There is increased need for solution to communicate larger data over the PON network. In this study, two problems including bottleneck and the capacity load problem were investigated and based on this, a solution is proposed. For methodology, N number of Nodes is used for ringbased architecture which represent the complete PON system. The nodes are the save points are created for monitoring the nodes and tracking their network faults. The distance from each node is equal and there are N number of checkpoints. The source and receiver node are selected dynamically. A ring-based network model is proposed with the optimized solution, less data loss and higher speed. The proposed work sets a scenario which is based on ring topology with 08 number of nodes with same number of save points. 800 m * 800 m is the dimension of the topography. We found that time it took to transfer a packet is about 1.01 second.  For solving the bottleneck problem, the tree-based network model is used and accordingly, 4 sub-networks are taken in a hierarchal way.  Comparison of results based on packet delivery shows that proposed model has better time factor in terms of sending data compared to the existing system.
