Abstract

This paper presents a technique that uses a family of Reed-Solomon (RS) code for the assured delivery of short, high-importance messages over IP-based military wireless networks with encryption. Encryption devices drop malformed packets upon receipt, assuming that they may be the result of enemy attacks. To the session layer on the plain-text side, encryption devices introduce packet loss. The presented technique attempts to ensure the delivery of short, high- importance messages while optimizing for Speed Of Service (SOS) requirements and network throughput (i.e., the minimum number of redundancy packets is added to assure delivery within the SOS requirements). As a result, high-importance messages such as a call for fire are delivered in time over the encrypted wireless network, even if the network suffers from attacks or fading.
