Abstract
Wireless links are often asymmetric due to heterogeneity In the transmission power of devices, non-uniform environmental Noise and other signal propagation phenomenons. Unfortunately, routing protocols for mobile ad hoc networks typically Work well only in bidirectional networks. This paper first presents A simulation study quantifying the impact of asymmetric links on Network connectivity and routing performance. It then presents a Framework called BRA that provides a bidirectional abstraction of The asymmetric network to routing protocols. BRA works by maintaining Multi-hop reverse routes for unidirectional links and provides Three new abilities: improved connectivity by taking advantage Of the unidirectional links, reverse route forwarding of control Packets to enable off-the-shelf routing protocols, and detection Packet loss on unidirectional links. Extensive simulations of AODV Layered on BRA show that packet delivery increases substantially (two-fold in some instances) in asymmetric networks compared to Regular AODV, which only routes on bidirectional links. Index Terms—Ad hoc network, asymmetry, routing, unidirectional
Existing System:
The Data mining Algorithms can be categorized into the following:
– AODV Algorithm
– Classification
– Clustering Algorithm
Given databases of sufficient size and quality, data mining technology can generate new business opportunities by providing these capabilities:
-Automated prediction of trends and behavior.
-Automated discovery of previously unknown patterns.
Proposed System:
Here the system will take care of the scheduling of data packets between the source and destination computers.
-Job scheduling to route the packets at all the ports in the router.
-Maintaining queue of data packets and scheduling algorithm is implemented.
-FCFS scheduling and BRA scheduling is called for source and destination.
