The use of sensor networks has increased rapidly over the last years. Due to their low resources, sensors come along with new issues regarding network security and energy consumption. Focusing on the network availability, previous studies proposed to protect the network against denial of service attacks with the use of traffic monitoring agents on some nodes. But if the control nodes go down or get...
Sensor networks are intended to provide continuous coverage to monitored areas and to communicate their sensed information back to designated gateway nodes. Since sensors are battery-powered and the lifetime of each node is finite, the monitoring and communication functions compete for the same energy resources. It has been established that for sensor networks the goal of coverage-aware (as distinct...
The need for high system reliability and platform availability in DoD assets is an increasing necessity with the continuing combat deployment of service personnel coupled with the high usage rates for the equipment that they rely upon to complete their mission. In general, reliability is obtained through a variety of measures including precision design, reduction in the number of parts required for...
