Local Area Network Dynamic (LANDY) routing protocol: A position based routing protocol for MANET

The issue of routing and maintaining packets between mobile nodes (MNs) in the mobile ad hoc networks (MANETs) has always been a challenge; i.e. encountering broadcast storm under high node density, geographically constrained broadcasting of a service discovery message and local maximum problem under low node density. This requires an efficient design and development of a ‘light-weight’ routing algorithm which can be handled by those GPS equipped devices. Our proposed protocol, Local Area Network Dynamic routing (LANDY) uses a localized routing technique which combines an unique locomotion prediction method and velocity information of MNs to route packets, which is capable of improving the routing performance in advanced mobility scenarios by reducing the control overhead. Simulations have been carried out with randomising the mobility speed and number of nodes and the preliminary results illustrate that LANDY's performance is better compared to other position based routing protocols.
