Abstract:
Good connectivity helps in reducing the number of packet drop and improve network efficiency. Vehicular networks have a pattern of flow and a defined heading. Connectivity break occurs due to insufficient radio range. Dynamic coverage modulation varies the range to maintain coverage. In areas of high vehicle traffic, data packet loss would increase due to packet collision. To avoid this the coverage of node could be reduced and data handoff would be activated for maintaining connectivity. Shorter coverage in dense areas allows multiple nodes to communicate with minimal interfer- ence. Unnecessary transmissions lead to network congestion, adaptive sampling collects route information to determine its suitability for establishing communication. This work attempts at minimizing network congestion and reduce breaks in con- nectivity through dynamically modulated coverage, direction dependent data handoff and adaptive sampling. The algorithm has been simulated using OPNET and results reflect reduced packet drop.
