This paper studies the resource allocation in the heterogeneous wireless cognitive networks (HWCNs), and we used an end to end model to analyze the delay of the service of secondary users (SUs) in the HWCNs, and proposed a joint resource allocation algorithm based on convex optimization theory considering the arrival probability of the primary users (PUs) to minimize the delay of end-to-end communication...
Abstract-This paper deals with an efficient and energy-saving channel assignment scheme which is applicable to the Wireless Sensor Network (WSN). In actual application, there exist inevitably serious interference and conflict between nodes due to their large quantity and density in WSNs. Usually, the sensor nodes in WSNs rarely move and the their energy is also limited. So in this paper, we divide...
