Summary: Real-time video streaming is delay sensitive. It has minimum bandwidth and QoS requirements. Achieving target QoS for video streaming is challenging in a decentralized and self-organized MANET. Cryptography algorithms offer confidentiality of shared data, but they have computation cost. Our work addresses the issue of delay overhead caused by the introduction of cryptography that directly affects video streaming performance. Our proposal is motivated by possibilities of adaptive security and multimedia service. We make an effort to identify why, when and how to deploy adaptation. We propose QaASs (QoS aware adaptive security scheme), an adaptive mechanism that counters the effect of delay overhead by adapting cryptography and multimedia properties, providing QoS while maintaining a required level of security. We evaluate our proposal through implementation and simulation.
