Distributed Delay: Improving Network Throughput by Reducing Temporal Saturation

We present the distributed delay (DD) extension to the self-balancing supply/demand (SBSD) routing protocols for mobile ad hoc networks. SBSD controls flooding depth to limit network congestion and provides redundant broadcasts at each hop for reliable end-to-end delivery. In DD, the delay between a node´s successive broadcasts increases with that node´s one-hop density, to reduce broadcast redundancy. Simulations consider road-based mobility with varying densities and network traffic levels. Our results show SBSD extended by DD reduces network congestion such that end-to-end delivery for total network traffic is improved without greatly slowing response time.
