This paper considers a multi-tier architecture for cloud-integrated body sensor networks (BSNs), called Body-inthe-Cloud (BitC), which is designed for home healthcare with onbody physiological and activity monitoring sensors. This paper formulates an optimization problem to integrate BSNs with a cloud in BitC and approaches the problem with an evolutionary game theoretic algorithm. BitC allows BSNs...
This paper proposes a novel system model where the concept of Cognitive Radio is introduced alongside conventional sensor network framework operating within the unlicensed ISM frequency band. The sensor nodes with channel sensing capacity are considered to be cognitive secondary user (SU) and the one without channel sensing feature are designated to be as the primary user (PU). Under the premise of...
This letter focuses on an energy-efficient hybrid spectrum access scheme in a vehicle-to-infrastructure uplink communication scenario in cognitive vehicular ad hoc networks (cognitive VANETs). Considering path loss exponent of the channel between a vehicle and an access point, a constrained optimization problem is formulated to minimize the overall energy consumption. Meanwhile, the quality of service...
Recently, Cognitive network is growing more and more attractive due to its capability of dynamic spectrum usage. When the dynamic spectrum is wideband, a sequential sensing scheme is proposed to sense the spectrum with low system complexity. Conventionally, parameters of sequential sensing are optimized subject to sensing time and detection performance constraints, such as false alarm and miss detection...
