SDTMRP (Software Defined Traffic Management Routing Protocol) for Efficient and Reliable Communication in Vehicular Networks

In the challenging infrastructure of Vehicular Ad-hoc Networks (VANET), researchers incorporated an emerging network paradigm called Software Defined VANET (SDVANET) which provided a safe and secure infrastructure for Intelligent Transportation System (ITS). To manage the traffic on a random route, researchers of this article have designed a novel, safe and secure routing protocol named as: Software Defined Traffic Management Routing Protocol (SDTMRP). SDTMRP has been suggested for VANETs that use node allocation, speed of vehicles, surveying and mapping. SDTMRP consists of the three processes listed below: (i) Route Accumulation Process, (ii) Query Control Mechanism, (iii) Route Maintenance. SDTMRP is transferring data between vehicular nodes using the strategy of Inter-zone Routing Protocol (IERP) and Intra-zone Routing Protocol (IARP) protocols. Also, validated and compared the performance of SDTMRP in variation of number of nodes (100, 150, 200, 250, 300, 350, 400, 450, 500) and speed is 50 km/hr with existing topology based routing protocol (Optimized Link State Routing Protocol (OLSR), Destination-Sequenced Distance-Vector (DSDV), Dynamic Source Routing (DSR), Ad Hoc on-Demand Distance Vector (AODV) and Zone Routing Protocol (ZRP)) using parameters: End-to-End Delay (EED), Throughput Ratio (TR), Packet Delivery Ratio (PDR), Overhead (OH). The work is implemented and modelled in NS3.33 and SUMO as mobility and network simulators. According to simulation data, SDTMRP outperformed all existing routing protocols in terms of every parameter, and it gave the transportation industry a more efficient and secure protocol.
