Acute direction route node selection multipath routing for VANET: Design approach

Vehicular Ad hoc Network (VANET) is the network of vehicles and road side units. The effective routing protocol is needed to route the data from source node to destination node in VANET. In available protocols, Directed Route Node Selection (DRNS) cannot detect the nodes movement in multiple directions for routing and in Ad hoc On-Demand Multipath Distance Vector (AOMDV) the route are not much stable. But DRNS is unable to detect nodes movement in other directions and specifically suited for the highway scenarios. A novel protocol, Acute direction Route Node Selection Multipath (ADRNSM) routing is proposed which is multipath protocol and adapt to 16 different directions of movement. This protocol is basically introduced to be aware of movement direction and engage nodes moving only in specific direction for routing to destination node. This protocol finds multiple paths to destination node and avoids engaging the nodes moving in other directions to increase the performance in urban scenario unlike DRNS protocol.
