Optimized Geographic Routing in Mobile Ad Hoc Network Using Gray Wolf Optimization

EAI Endorsed Transactions on Energy Web, 2020
The geographic routing protocol (GRP) in general seeks the location of sensor nodes to decide the routing path in mobile ad hoc network. This increases the routing overhead while finding the location of nodes.
