Intercell interference is a major limiting factor in wireless multi-cell networks. Recently, it has been shown that significant performance gains can be achieved by cooperation between base stations. Different degrees of cooperation are possible: From full cooperation, where multiple base stations form a virtual antenna array, to weak cooperation, where base stations take into consideration the...

BACKGROUND In the early stages of Pandemic (H1N1) 2009, border control measures were taken by quarantine stations to block the entry of infected individuals into Japan and community containment measures were implemented to prevent the spreading. The objectives of this study were to describe these measures and the characteristics of infected individuals, and to assess the measures' effectiveness...

While fifth-generation (5G) cellular is meant to deliver gigabit peak data speeds, low latency, and connection billions of devices, 6G already on the way, half world population living in rural areas are still facing challenges connecting internet. Compared urban areas, users greatly impacted by income, high cost backhaul connectivity, limited resources, extreme weather, natural geographical lim...

We address the problem of detecting a rogue base station (BS) in WiMax/802.16 wireless access networks. A rogue BS is a malicious station that impersonates a legitimate access point (AP). The rogue BS attack represents a major denial-of-service threat against wireless networks. Our approach is based on the observation that inconsistencies in the signal strength reports received by the mobile st...

SkyNET is a stealth network that connects hosts to a botmaster through a mobile drone. The network is comprised of machines on home Wi-Fi networks in a proximal urban area, and one or more autonomous attack drones. The SkyNET is used by a botmaster to command their botnet(s) without using the Internet. The drones are programmed to scour an urban area and compromise wireless networks. Once compr...

This review considers how a honey bee colony optimally controls the timing and type of new comb construction. Optimal timing requires bees to balance the energy costs of construction with the opportunity costs of lacking storage space during nectar flows. They do so by conditioning the start of building on (1) the attainment of a fullness threshold, and (2) the availability of nectar. A dynamic...

BACKGROUND Honey bee (Apis mellifera) drones and workers show differences in morphology, physiology, and behavior. Because the functions of drones are more related to colony reproduction, and those of workers relate to both survival and reproduction, we hypothesize that the microclimate for worker brood is more precisely regulated than that of drone brood. METHODOLOGY/PRINCIPAL FINDINGS We as...

This paper addresses the problem of locating base stations in a certain area which is highly populated by mobile stations; each mobile station is assumed to select the closest base station. Base stations are modeled by players who choose their best location for maximizing their uplink throughput. The approach of this paper is to make some simplifying assumptions in order to get interpretable an...
