Location-Based Flooding Techniques for Vehicular Emergency Messaging

Overview This paper analyzes the scalability of message flooding protocols in networks with various node densities, which can be expected in vehicular scenarios. Vehicle safety applications require reliable delivery of warning messages to nearby and approaching vehicles. Due to potentially large distances and shadowing the delivery protocol must forward messages over multiple hops, thereby increasing network congestion and packet collisions. In addition to application-layer backoff delay and duplicate message suppression mechanisms, location-based backoff techniques have been proposed for vehicular networks. The paper proposes a new hybrid method of location-based and counter-based method, and study several variants through simulations.

What are IP VPNs good for?

Because IPSec encrypts data before forwarding it over the IP VPN and then decrypting it, there's a delay that makes using these apps together tough, and practically prohibits voice packets. Infonet is now saying that businesses can buy packet...
