ACTS is a non-profit organization based in Norwich, Vermont. Since 1986 ACTS has partnered with rural villages in the mountainous Locomapa region of the Yoro district of Honduras with a focus on sustainable community development. In a region where a 6th grade education is the norm, a major initiative of ACTS has been improving educational opportunities. In 2008 ACTS helped the community of El Rosario...
Open Source Hardware is widely used as enterprise standard device because it has high performance for its price. Traditional enterprise Wireless Local Area Network has the limitation of functionality and scalability by the deployed network equipment. To solve this problem, we propose ‘Web of Place Access Point’ using raspberry pi that enable to manage the scale of the network and to provide enterprise...
With the development of cooperative robotic applications, variable kinds of communication method between robots are applied. The quality of communication has directly affect to the movement of each mobile robot in system. This paper proposes an approach to control the communication between 3 mobile robots by using wireless communication. In this paper, we focus on three main parts. In the first part,...
We argue that, a wireless sensor does not have to implement a full networking stack in order to be a part of an energy efficient sensing application as long as it can deliver its sensed data to an Internet connected device over a single hop. Current hardware industry trends indicate the possibility of implementing wireless sensors for a low cost with simple capabilities. This poster highlights our...
The Deterministic Networking paradigm, which is prevalent in Operational Technology (OT), is now getting traction at the IETF and the IEEE, to enable the convergence of OT with Information Technology (IT), and the Industrial Internet vision, whereby the automation world can leverage IT technology to optimize OT processes. New Working Groups (WGs) are now emerging at the IETF to develop new routing...
Internet connectivity in most rural African areas has been viewed as a major challenge due to lack of reliable power, scarcity of network expertise and expensive installation of network equipment. With the rapid development of wireless technologies, Wireless Mesh Network (WMN) has emerged as a promising networking infrastructure, bridging the digital divide between the urban and rural areas. However,...
Introducing an IP-based communication system into the mountain rescue domain would enable carrying out search and rescue missions in an effective way. With efficient mobility and multihoming support, a Mountain Rescue Team would be able to establish more effective and reliable Internet communication. In this paper, we present the Multihomed Mobile Network Architecture (MMNA), a comprehensive multihomed...
Wireless technologies and services in emerging markets have been central to enabling the communications explosion over the last decade that has, in many ways, revolutionized the lives and the economies of the people living there. The nature of the markets and the competitive dynamics in these regions are undergoing some delicate but very important shifts. This white paper analyzes the leading opportunities...
Over the past few years, there has been a trend of increasing demand for faster data rate and shorter delay in wireless communication. Because data rate and delay are both directly related to bandwidth consumption, the trend produces the imminent problem of reaching the bandwidth limit. The cap on available bandwidth forces allocation to be the focus of responses to the trend. In this article, the...
In this study, we present a lightweight context-aware security system for wireless Internet access. Our system consists of an Android mobile application and a web browser plug-in called G&ALF. Android application is used to retrieve the public configuration parameters of available wireless connections, evaluate the context and assess the security level of the wireless network. Then, the assessment...
Wireless Multi-hop Infrastructures (WMIs) enable mobile users to access the Internet through wireless multi-hop connections. Compared with conventional network infrastructures, WMIs have the low cost and flexible network deployment. The applications of WMI include smart cities, emergency responses and Internet of things. In emergency situations, WMI networks may have energy constraint. Furthermore,...
Social Networking Sites (SNS) require a centralized system accessible via Internet. SNS' owners are in control of user's data; this often leads to data theft, piracy and privacy issues. This paper proposes a way of socializing with people in surrounding places by using a ubiquitous social sensor network system (USSNS) where Wireless Sensor Node interact in a peer-to-peer mode without the need of Internet...
A key challenge in Internet access applications of Vehicular Ad Hoc Networks (VANETs) is the rapid distribution of Internet content to car users with low cost. The content distribution service among vehicles is free, but it is susceptible to frequent interruptions and failures because of the volatile and spotty vehicle-to-vehicle (V2V) channel. To make V2V communi-cations play a positive role in Internet...
The opportunistic utilization of third party WiFi access devices to offload customer traffic from the mobile network has recently gained momentum as a promising approach to increase the network capacity and simultaneously reduce the energy consumption of the radio access network (RAN) infrastructure. To foster the opportunistic utilization of unexploited Internet connections, we propose a new and...
Wireless standardization activities such as Bluetooth V4.x have led to an explosive growth in innovative short-range wireless devices capable of providing various services to assist everyday life. Allowing Machine-to-Machine (M2M) communication between these M2M devices also enable new commercial service opportunities. Typically, short range M2M devices need another capable device such as a smartphone...
Low power networks form a fundamental supporting communication platform for various "things" that help in realising the Internet-of-Things (IoT) vision of better, smarter, interconnected world. The IoT paradigm is an emerging area that comes with a number of challenges that requires rethinking of how conventional communication and computational mechanisms can be adapted for this new model...
Internet of Things (IoT) is becoming increasingly important for today's market and gained a lot of attentions both in academia and industry. IoT can be applied into wide range of application scenarios. In case of constrained environment, for communication, resource-constrained devices are expected to employ the lightweight mechanisms. In order to provide intelligent facilities for constrained IoT...
We propose a routing protocol for drive-thru Internet access in delay tolerant vehicular networks. The contribution of this paper is two-folds. First, we propose a new approach which utilizes the concept of delay tolerant network (DTN) to supplement the conventional communication approach. Second, we propose an algorithm to schedule DTN transmissions in order to maximize the system throughput. The...
Distributed and cooperative caches (DCCs) enabled small-cell network (SCN) has been a common approach for improving QoE perceived by mobile users (UEs) and reducing backhaul traffic load. In this paper, we propose a joint wireless and backhaul load balancing (JWBLB) framework for DCCs enabled SCNs with the objective to minimizing the system content transmission delay. The JWBLB is achieved through...
The main node (router, coordinator, gateway) of ZigBee based wireless sensor network enhanced by adoption of Bluetooth module is proposed in this paper to provide easy way for industrial field measurement with low-cost and portability. Only a Bluetooth module and basic circuits are required to be added to the original ZigBee network and a simplified physical model is designed and verified in wireless...
