A QoS oriented distributed routing protocol for Hybrid Wireless Network :First review ppt

This document presents an outline for a project on developing a QoS-oriented distributed routing protocol for hybrid wireless networks. It discusses existing work that suffers from overhead and scalability issues. The proposed work incorporates five algorithms to select neighbors, schedule packets, adjust segment size based on mobility, eliminate redundant traffic, and reduce redundant data to improve QoS metrics like transmission delay, throughput, and capacity while reducing overhead. It is claimed that using single-hop transmissions can improve performance by reducing overhead, link failures, and improving QoS.

1. A Lantern-Tree Based QoS on Demand Multicast Protocol for A wireless Ad hoc Networks  In this paper introduce for bandwidth routing protocol for QoS support in a multi-hop mobile network  The QoS on demand multicast protocol determines the end to end bandwidth calculation and bandwidth allocation from source to a group of destination  In this paper identify a lantern tree for developing the QoS multicast protocol to satisfy certain bandwidth requirement 7 SVS COLLEGE OF ENGINEERING 7-Oct-14
LTM: Lantern-Tree based QoS Multicasting protocol  The LTM protocol is achieved by the tree phases  Lantern identification  Lantern-tree construction  Lantern-tree maintaence 8 SVS COLLEGE OF ENGINEERING 7-Oct-14
Phase-1: Lantern Identification  To identify the lantern, local link state information collected fro each node in the MANET  The link state information includes all one-hop and two hop high boring nodes and corresponding free time slot list of these nodes  The lantern identification is dependent on the bandwidth is sufficient  a, b - nodes  Sn- shared time slot between nodes a and b n1(sn1) a : b nk(snk) 9 SVS COLLEGE OF ENGINEERING 7-Oct-14
Phase-2: Lantern-Tree construction  The lantern-tree construction phase in divided into two operation  The lantern-path search operation  Based on the identified lantern many lantern paths from a source to a given set of destinations are constructed  The lantern-path with a reliable mechanism  Based on the multiple lantern path a lantern-tree is constructed with a reliable mechanism is provided ni,1(sni,1) ai : bi ni,ki(sni,ki) 10 SVS COLLEGE OF ENGINEERING 7-Oct-14
Phase-3: Lantern-Tree maintaence  Lantern-path and sub-path fails then we try to search fro a backup sub-path to replace the failed sub-path  When the QoS requirement could not be satisfied even using the proposed LTM for they dynamical topology change, the lantern-tree maintaence phase will start its maintaence operation to maintain a lantern-tree structure  If it can maintain a lantern-tree structure, the real time data transmission will be continued and it cannot maintain transmission will be stopped 11 SVS COLLEGE OF ENGINEERING 7-Oct-14
Advantages  Using multiple paths provide high aggregate of the network bandwidth  High access rate and high stability due to using multiple path lantern –tree  Efficient utilization of the network bandwidth especially when the bandwidth is limited 12 SVS COLLEGE OF ENGINEERING 7-Oct-14
Disadvantages  Increasing the number of links increase the contention at the MAC layer  It takes a long time to find all the path and shares the time slots between the neighboring nodes  Node have to process and store more information about sub-path which wastes the resource 13 SVS COLLEGE OF ENGINEERING 7-Oct-14
2. A QoS-Aware Multicast Routing Protocol  In this paper introduced for QoS multicast routing protocols are pivotal in enabling new receivers to join a multicast group.  QMRP achieves a scalability by significantly reducing the communication overhead of constructing a multicast tree  This is achieved by switching between single-path routing And multiple-path routing according to the current network conditions. 14 SVS COLLEGE OF ENGINEERING 7-Oct-14
QMPR: QoS-Aware Multicast Routing Protocol  QMRP implements a five-state state machine at every node ,such as  Initial state  Single path state  Multiple path state  Failure state  Success state 15 SVS COLLEGE OF ENGINEERING 7-Oct-14
QMRP parameters  Maximum Branching Level(MBL)  Maximum Branching Degree(MBD)  The overhead can be controlled by these two parameters MDL=m, MBD=X, The maximum number of nodes allowed to enter the MP states is 16 SVS COLLEGE OF ENGINEERING 7-Oct-14
Advantages  Using on-demand maintenance reduces the control overhead by starting from a node that the link failure occurs  The packet delivery ratio is high because of using forwarding nodes as ODMRP  The protocol is loop free  Limiting periodic maintenance to mesh nodes and neighbor nodes reduce the control overhead 17 SVS COLLEGE OF ENGINEERING 7-Oct-14
Disadvantages  The network bandwidth is not efficiently utilized because it use only routes that support the require bandwidth  Collecting the bandwidth information of the nodes periodically introduce extra processing overhead and contention on the wireless medium  Flooding the network with control packets consumes the limited network bandwidth especially for non-participating nodes 18 SVS COLLEGE OF ENGINEERING 7-Oct-14
Existing system  Reference paper-1  Overhead  Scalability  Reference paper-2  Overhead  Transmission delay 19 SVS COLLEGE OF ENGINEERING 7-Oct-14
Proposed system  This paper proposed to it can provide the high QoS performance such as  Overhead  Transmission delay  Mobility-resilience  Scalability 20 SVS COLLEGE OF ENGINEERING 7-Oct-14
Algorithms  It incorporates the five algorithm  1. Neighbor Selection Algorithm : To meet the transmission delay requirement  2. Distributed Packet Scheduling Algorithm: Reduce the transmission delay  3. Mobility based Segment Resizing Algorithm: Adjusts segment size according to node mobility in order to reduce the transmission time. 21 SVS COLLEGE OF ENGINEERING 7-Oct-14
Algorithms (cont..)  4. Traffic Redundant elimination Algorithm: To increase the transmission throughput.  5. Data redundancy elimination based transmission Algorithm: To Eliminate the redundant data to improve the transmission QOS 22 SVS COLLEGE OF ENGINEERING 7-Oct-14
Solution Methodology  Single hop reduce the overhead, link failure  By monitoring the Energy level, solve the energy harvesting problem.  Improve the QOS level by modifying the multi hop as single hop. 23 SVS COLLEGE OF ENGINEERING 7-Oct-14
Advantages  The QOD Protocol chooses qualified neighbors for forward the packet, Schedules the packet transmission, resizes the packet and increase the transmission throughput.  By using the Single hop, the overhead, collisions, collusion, traffic , link failure will be reduced and also the QOS will be increased 24 SVS COLLEGE OF ENGINEERING 7-Oct-14
