Query: A Novel Grid Based Dynamic Energy Efficient Routing Approach for Highly
  Dense Mobile Ad Hoc Networks   We have proposed a novel Grid Based Dynamic Energy Efficient Routing (GBDEER)
approach which is aimed to construct an energy efficient path from source to
destination based on grid area, where each grid will have three deferent levels
of transmission power.
