ABSTRACT
Resources are scheduled dynamically for the relay based OFDMA wireless network.
Relay station perform network coding with uplink and downlink sessions of a mobile station.
To improve the flexibility for resource allocation dynamic TDD technique is used.
Resource scheduling algorithm is used to opportunistically schedule the subchannel, transmission power, network coding and time duration of each phase in each time slot.
EXISTING SYSTEM
Subchannels are allocated with equal power distribution .
Failed to provide optimal solutions for joint subchannel and power allocation problems.
PROPOSED SYSTEM
Resource allocation problem is solved for OFDMA based wireless network.
Optimal opportunistic resource scheduling algorithm utilize two techniques,
1.Network coding
2.Dynamic TDD
Quality of Service required by each mobile station is satisfied by maximizing the average weighted-sum rate for both uplink and downlink sessions of all mobile station.
SOFTWARE REQUIREMENTS
The software requirements are as follows,
Operating system : Windows XP
Simulation Tool : MATLAB 7.0
CONCLUSION
From this, it is expected that performance improvement is better compared with other algorithms that do not consider network coding and dynamic TDD.
