Scalability of Modified Aodv-Uu Routing Protocol for Smart Grid : 9783659465611 : 22 Jan 2014 : Smart grid (SG) is said to be the grid of the 21st century. In SG, networking and communication facilities are included with the conventional grid system, and it allows the flexibilities of distributed control, power generation and load management. All of these issues can suitably be controlled by the efficient design of SG. The success of SG depends on the success of efficient networking of connected nodes and loads. In this work, wireless sensors have been considered as SG sensing nodes, and adhoc on demand distance vector (AODV) routing has been considered as the networking protocol for SG. The scalability of AODV has been studied in the simulation environment. We have proposed a modified AODV protocol for the SG application which is based on the concept of making some nodes more intelligent than others. The obtained simulation result shows a significant reduction of delays in the propose
