Environment monitoring is key for multiple applications and requires that devices used in acquiring environment data to be scattered over a wide area, but at the same time maintain accessibility of information from all sensor nodes. Although many Wireless Sensor Networks are based on the IEEE 802.15.4 standard for low-power, Wi-Fi networks offer the most accessibility and interoperability with other...
Unmanned aerial vehicles (UAVs) can be used as aerial wireless base stations when cellular networks go down. Prior studies on UAV-based wireless coverage typically consider an Air-to-Ground path loss model, which assumes that the users are outdoor and they are located on a 2D plane. In this paper, we propose using a single UAV to provide wireless coverage for indoor users inside a high-rise building...
Among the mobile applications contributing to the surging Internet traffic, video applications are some of the biggest contributors. Most of these video applications use HTTP/HTTPS tunneling making it difficult to apply port based or packet data based identification of flows. This makes it challenging for network operators to enforce bandwidth regulation policies for app based service differentiation...
To address the challenge arising from mobile users' increasing demands for multimedia services, applying content caching in heterogeneous networks (HetNets) is regarded as an effective way to offload traffic and improve the capacity of mobile networks. In this paper, we aim at designing novel content caching strategies in HetNets to offload the network traffic and support users' requests locally....
This paper proposes a dynamic channel utilization method to minimize transmission delay by considering radio interference and wireless link rate for software defined multi-channel wireless mesh networks (SD-WMN). The OpenFlow technology, which enables us to control flows by programming, is employed to effectively utilize multiple channels in SD-WMN for traffic balancing. Existing methods assume fixed...
The paper considers the problem of proactive caching (or replication) of content in a collection of caches which can form a group and collectively satisfy content requests of their users (clientele); such caches can be the ones associated with close-by base stations. Under significant user similarity, avoiding caching the same content in multiple locations within the group and leaving room for more...
Internet Protocol version 6 (IPv6) is presently gaining demand in almost every region of the world. In near future, IPv6 would be the key area of research and expansion in the internet protocol standards. IPv6 was built with the aim of improving the mobility and communications among these devices. Mobile IPv6 is becoming a highly demanding research area under which a lot of investigations are yet...
During a disaster incident, existing network infrastructures might either be damaged or overloaded. However, disaster operations require real-time and low latency data communication, especially live video and audio streaming, as well as in integration with social networks. Thus, deployed tactical networks face several challenges to connect intervening teams. To date, there is still a lack of routing...
In these days, the Internet is growing and the amount of user to use network increases rapidly. The mesh(ad-hoc) network has studied for many areas where people can't use the Internet. Also, mesh(ad-hoc) network is used for special purposes, and it expands its domain recently. However, low transfer rate and small coverage are a critical issue in mesh(ad-hoc) network. In this paper, it suggests improving...
Real-time video communications has been incorporated into many instant communication tools such as ichat, Skype, QQ, etc. Real-time video communications has low delivery delay requirement, which imposes great challenge to the provisioning of such services. To address this problem, in this paper, we propose a selective redundant transmission mechanism to support real-time streaming on multi-interface...
In this paper, we propose an improved MANET gateway selection scheme suitable for disaster recovery applications. Having an infrastructure less and decentralize features, MANET is well suited to bring the network back that has been collapse after a disaster. In this paper, we focus on improving throughput performance of MANET by designing a better gateway selection scheme. The key idea is to eliminate...
Internet of Vehicles requires reliable Inter-Vehicular communications. Such a requirement is challenging since the wireless communication channel is very erroneous and lossy in city environments. A lot of solutions for connecting vehicles to the internet have been proposed. However, existing multi-hop gateway discovery solutions do not consider, a key issue, the unreliability of broadcast in city...
Named Data Networking (NDN) has emerged as a new and promising information-centric architecture for the future Internet that is also gaining momentum in Wireless Sensors Networks (WSNs) as an alternative paradigm to traditional IP. However, the main solutions in current works lack energy efficient design to meet the severely limited energy resources in WSNs. Moreover, the NDN architecture cannot natively...
The urban road traffic congestion is becoming a serious problem. The number of vehicles waiting to be processed at the intersection is rising sharply with the increase of the traffic flow, and it cannot be effectively scheduled by the traditional traffic lights. A real-time vehicle scheduling algorithm based on the traffic flow to improve the vehicle scheduling ability of the intersection and reduce...
Free open wireless Internet access is a complimentary Wi-Fi service offered by most coffee shops, fast food restaurants and airports to their customers. For ease of access, these Wi-Fi networks are inherently insecure where no authentication/ encryption is used to protect customers wireless data. An attacker can easily deceive a wireless customer (WC) by setting up a rogue access point (RAP) impersonating...
Rateless erasure code (REC) is an erasure code, where the encoder generates a potentially infinite number of encoded symbols and the original message can be reconstructed from a sufficient number of correctly received packets. Many REC-based transmission protocols have been proposed for improving network throughput in lossy channel. However, state-of-the-art RECs (such as LT code and Raptor code)...
In the high-speed train, passengers want infotainment services which provide users with useful information about the area they are passing by, or information about their destination. This paper introduces dynamic SNS for train application which enriches user experiences with ad-hoc group chatting, contents sharing, recommendation based on user preference and location, and train environment information...
After a disaster, it is unlikely to expect current terrestrial infrastructures to provide the coverage and the Quality of Service required by emergency operators. Currently, PPDR operators go towards a portable LTE infrastructure that provides an access network to field operators, backhauled by a wireless mesh network that can route traffic from and towards Internet through a satellite gateway. We...
