Abstract
This report evaluates the performance of a recently proposed protocol for simultaneously delivering broadcast situational awareness traffic and performing proactive routing in a Tactical Edge Mobile Ad Hoc Network (TEN). The proposed routing strategy—called SER-SA, for secure and efficient routing by leveraging situational awareness messages—takes advantage of the fact that nodes in future tactical networks are expected to periodically broadcast Situational Awareness (SA) messages to other nodes in the network, indicating their position and status. With simulations examining various scenarios such as different network size, radio transmission range, and mobility patterns, we compare the performance of SER-SA against other popular Mobile Ad Hoc Network (MANET) routing protocols—specifically, Optimized Link State Routing (OLSR) and Ad Hoc On Demand Distance Vector Routing (AODV). When considering channel utilization and traffic delivery ratio as the performance metrics for our study, we observe that there is no “silver bullet,” i.e., there is no single best routing protocol for every considered TEN scenario. This report highlights the cases under which certain protocols offer benefits over others, and when a particular routing protocol is advantageous.
