摘要：Adhoc On-demand Distance Vector (AODV) is a routing schema for delivering messages in a connected Mobile Adhoc Network (MANET). In MANETs, a set of nodes are used to route the data from source to destination and it is assumed that nodes are distributed over the entire region. Connectivity between any sources to destination pair in the network exists when they are in radio range of each other. The technique used to deal with the issues called Local Repair. Local Repair is an important issue in routing protocol which is needed for minimizing flooding and performance improvement. Local Repair is one of the major issues in the protocol; routes can be locally repaired by the node that detects the link break along the end to end path. Local Repair will increase the routing protocol performance. In this paper, the existing Local Repair Trial method in AODV is extended to achieve broadcasting and minimizing the flooding. The Enhanced protocol first creates the group of mobile nodes then broadcasting can be done and if the link breaks then local repair technique can be applied. In the network the numbers of intermediate nodes are increased by using Diameter Perimeter Model. Enhanced AODV-Local Repair Trial (EAODVLRT) protocol is implemented on NS2 network simulator. Simulations are performed to analyze and compare the behavior of proposed protocol (EAODVLRT) for varying parameters such as size of network, node load etc. Proposed protocol has been compared with the existing AODV-LRT in terms of routing load, Data delivery ratio.
