Abstract: This report presents the results of a power utilization and packet loss study for the Extremely Lightweight Intrusion Detection (ELIDe) algorithm on an Android-based mobile device. Our results show that the hashing and inner product operations performed by the core ELIDe program alone results in negligible additional power consumption. The bulk of the excess power consumption caused by the ELIDe program is attributable to the data capturing of the Libpcap library and the internal hardware of the device that performs data capturing based on the limitation of the mobile device. Power consumption is tightly linked to the total number of network packets processed by the device, but remains tractable within the operating range of ELIDe. Results also show that ELIDe is capable of handling throughput rates of up to approximately 2.5 megabits per second (assuming a normal distribution of packet sizes) with no significant packet loss.
