The Kinesin superfamily proteins (KIFs) are major molecular motors that transport diverse set of cargoes along microtubules to both the axon and dendrite of a neuron. Much of our knowledge about kinesin function is obtained from studies on axonal transport. Emerging evidence reveals how specific kinesin motor proteins carry cargoes to dendrites, including proteins, mRNAs and organelles that are crucial...
Underwater Wireless Networking (UWN) schemes and applications have been attracting considerable interest with both industry and the research community. The nature of water, as a carrier medium, imposes very significant constraints on the both the characteristics and information carrying capacity of underwater communication channels. Currently, acoustic and optical are the two main physical platform/channel...
Efficient data communication among autonomous under-water vehicles (AUVs) is difficult. Challenges include the long propagation delays arising with acoustic communication solutions, and line-of-sight requirements for optical transceivers. Existing multi-hop routing approaches are not always appropriate due to node mobility. This work presents a centralized approach to network control, exploiting the...
Satellite systems such as Low Earth Orbiting (LEO) networks play an important role in the next generation 5G networks. To facilitate the integration of satellite and terrestrial networks, software-defined networking (SDN) is embraced which brings flexibility, user-customized services and reduces the cost of network configurations. However, it has been long known that communications via LEO satellite...
While geo-routing is a promising routing algorithm in urban vehicular ad-hoc networks (VANETs), there is still much work to be done for it to become truly usable for such environments. One of the biggest obstacles to this goal is the intermittent nature of VANETs due to mobility. Traditional geo-routing algorithms do not perform well in these conditions because they drop packets whenever they cannot...
Neighbor discovery plays a crucial role in the formation of wireless sensor networks and mobile networks where the power of sensors (or mobile devices) is constrained. Due to the difficulty of clock synchronization, many asynchronous protocols based on wake-up scheduling have been developed over the years in order to enable timely neighbor discovery between neighboring sensors while saving energy...
This paper proposes a network-aware resource management scheme that improves the quality of experience (QoE) for adaptive video streaming in CDNs and Information-Centric Networks (ICN) in general, and Dynamic Adaptive Streaming over HTTP (DASH) in particular. By utilizing the DASH manifest, the network (by way of a logically centralized controller) computes the available link resources and schedules...
Recently, Information-Centric Network (ICN) has been attracting much attention with its promising future as next-generation Internet architecture. While ICN is scalable and efficient in Internet, concerns are raised when ICN is deployed in frequently-disruptive vehicular ad-hoc networks. In this paper, we introduce DT-ICAN, which provides low-cost, bandwidth efficient network operations to conquer...
With the spread of mobile Internet, users have increased opportunities to retrieve content from the content producer via the application in mobile information-centric network. For security consideration, the content data must be encrypted and the content producer must be authenticated. Content data is signed by the producer and delivered to the requester via the public-key cryptography. A Certificate...
Indoor localization with conventional GPS devices is too difficult because the satellite signals are too weak. Several alternate schemes have been proposed, from RF signal strength to radio signatures. In this paper we consider the indoor localization of a wheelchair. This is important to guide the handicapped on predefined wheelchair-friendly routes in a building, for example. For indoor wheelchair...
