1、ON THE RESEARCH 0F LABEL S、TCHBASEDMOBILE ADHOCNETWORK BASED,TIPATHAB STRACTAd。hoc network composed of mobile nodes with wireless communication device are typically characterized by their multihop, temporary and un-centerMPLS(Multiprotocol Label Switching)is a new network technology using label to i
2、nduct data fast transfer and switching on a open telecommunication networkImport MPLS into Adhoc network means combining switching of MPLS datalink layer and routing of Ad-hoc network layer,provide connectionoriented switching based on IP routing protoc01Doing this can improve the deficiency of the
3、Adhoc,provide huge advantage in fast switching,traffic engineering, Qos and virtual VPNFirstly,this paper introduces the concept and characteristic of Ad-hoc networks and MPLSThen introduces architecture and algorithm of label switch-based mobile Adhoc network based Multi-path,promote a network labe
4、l switching protocol AODLS(Ad-hoc On-demand Label Switching),also simulate the performance of this protocol in OPNETnetwork simulatorThis paper puts forward a new protocol in Adhoc network which based on multi-path label switchingThis protocol based on TRNDAODV multipath protocol,import label switch
5、ing of MPLS, realize the separation of routing and forwarding in Adhoc network Realizing label switching in Adhoc network also provides two advantagesFirst,using a fix and short label replaces traditional longestpacket matching,can obtain better forwarding performance,make the process of forwarding
6、easier,even can implement by hardwareSecond, separate routing and forwardingFor example,the same forwarding algorithm can support unicast and multicast,different routing function lieIlion the organization of output labelSo we do not need change forwarding mechanism when add a new routing or control
7、functionThis paper implements AODLS protocol in OPNET and compares its performance with AODV The result shows that AODLS decreases the end。toenddelay,increases the packet delivery,decreases the routing cost and increases the QoS of networkFinally the conclusions of this paper and suggestions for fut
