Route Optimization for Intra Communication of a Nested Mobile Network

Network mobility, i.e. Internet access services for a moving network as a single unit brings about new challenging issues. A nested mobile network is a hierarchical form of multiple mobile networks. Nested mobile networks suffer from a pinball routing problem. This problem becomes more serious in the case of a communication between any two nodes in the same nested mobile network. To solve this sub-optimality, we propose a nested NEMO route optimization (NNRO) protocol to retain the mobility transparency as the NEMO basic support protocol and to reduce the communication cost of any two nodes in a nested mobile network. The results of simulation reveal that the proposed NNRO protocol efficiently supports communication within a nested mobile network.
