Traffic grooming issue is important to reduce the network design cost and improve network operational performance. In full grooming network services provided to users are costly due to their throughput; same nearly performance will be achieved by grooming some nodes called as "sparse grooming network". In this paper we design heuristic approach for selection of G-node based on Maxconnectivity nodes in Optical Mesh network. Our work mainly focus on dynamic traffic connection request .Simulation results show that blocking performance of Sparse Grooming Network similar with as full grooming Network.
