Energy Analysis of Confidentiality-Enhanced Multipath Streaming in Multi-Hop Wireless Networks

High security and low energy consumption are two of the most important features in implementing today´s wireless network systems and applications. They are not totally unrelated in terms of system design. In fact, there is a tradeoff relationship between security and energy. Generally the more secure a system is, the more energy it consumes. In this paper, we integrate a confidentiality (security) enhancement technique with an energy-saving scheme together, and analyze its power consumption. The multipath data allocation improves confidentiality, and the interference-aware minimum energy routing preserves transmission power. Based on our investigation, low density wireless networks can provide both enhanced security and reduced energy consumption at a reasonable level.
