Performance Analysis of Various Routing Protocols for Motorway Surveillance System Cameras' Network

The Motorway Surveillance System (MSS) is one of the most important technologies used to collect information about road conditions and then provide that collected information to motorway users. The routing in networks used by these systems is a critical task due to the highly dynamic environments. This paper presents performance evaluations, comparisons, and analysis for three routing protocols (AODV, DSR, and OLSR) on a selected MSS scenario. The evaluation and analysis were performed for several different performance metrics and under varying network conditions. The results demonstrate that, under various vehicle speeds and several different traffic loads, AODV outperforms DSR and OLSR protocols, with respect to network throughput (by 36.7% and 9.1%, respectively) and protocol overhead (by 23% and 45.2%, respectively). In contrast, the packet transmission delay when using DSR is shorter than when using AODV (by 26.7%) and OLSR (by 17.1%). The conclusions of this study are important to provide a qualitative assessment of the applicability of these protocols to real-world motorway surveillance systems, and also as a basis for developing new ways to improve routing performance in this type of systems.
