Crowd sensing exploits users' smart devices and human mobility to collect information on a large scale. To realize a crowd sensing campaign, sensing tasks with spatio-temporal requirements are distributed to the devices that can provide the requested information. Typically, the distribution of sensing tasks relies on a centralized communication infrastructure such as cloud servers. However, such an...
This paper presents an IoT (Internet of Things) system designed to allow the monitoring and control of parameters of the users' vehicles, anytime and anywhere in the world, through the Internet. The system prototype was developed and tested using an electric vehicle (EV) and the respective sensor systems. The main components of the proposed IoT system are: a Bluetooth Low Energy (BLE) intra-vehicular...
This paper discusses the challenges in developing an IoT platform for registering, discovering and composing heterogeneous services from multiple provider types, viz., Wireless Sensor Networks (WSNs), Web Service Providers (WSPs), and Autonomous Service Providers (ASPs), without human intervention. The platform executes a service composition in a decentralised fashion, with a mechanism to detect service...
The near future Internet of Things (IoT) allows devices to discover and to establish cooperation autonomously in an opportunistic manner. While the incentive service is available, the front-end inter-organisational devices may help each other not only on sharing information, but they can also share their Internet connection towards saving energy. Considering that different devices may have been configured...
The article touches aspects of security in Wireless Sensor Networks. It begins with a review and classification of existing types of threats and protection methods. The main part of the paper presents the results obtained during development of a threat detection system for WSN network. The described approach is based on a mobile platform which allows separation of security mechanisms and the software...
With recent advancements of Information and Communication technologies (ICT), Internet of things (IoT) development has just started creating a significant value across people, processes and organizations. There are numbers of applications across energy, transportation and public safety sectors that have linked with economic growth in GDP and therefore, governments are taking serious actions to enhance...
This work focuses on mitigation of the network congestion in a Machine to Machine (M2M) cloud. Since the inception of M2M cloud communication technology, the number of M2M devices has radically increased. This has consequently increased the overall traffic of the network which, in turn, makes the entire network congestion prone. The work assumes an underlying clustered network topology of the M2M...
Due to wireless and decentralized nature, multi-hop wireless networks are attractive for variety of applications. These properties also pose significant challenges to their developers and so require new types of algorithms. In cases where traditional wired networks usually rely on some kind of centralized entity, in multihop wireless networks nodes have to cooperate in a distributed and self organizing...
This paper deals with the movement pattern of mobile sinks in Wireless Sensor Network for efficient collection of information by the mobile sinks. We propose a path determination algorithm for the sinks to move in the network and cover the whole network area as much as possible. Multiple mobile sinks will move in their defined path based on the path determination algorithm to collect data from static...
Efficient collection of urban solid waste is a growing problem for cities and urban areas. Optimizing service routes based on actual waste bin fill level information can result in significant cost savings, reduced emissions, and improved city image. Fill level sensor installation and networking at an urban scale poses unique challenges. We describe Dynacargo, an innovative smart city application that...

The Internet is smoothly migrating from an Internet of people towards an Internet of Things (IoT). By 2020, it is expected to have 50 billion things connected to the Internet. However, such a migration induces a strong level of complexity when handling interoperability between the heterogeneous Internet things, e.g., RFIDs (Radio Frequency Identification), mobile handheld devices, and wireless sensors...
This paper proposes an innovative Internet of Things (IoT) architecture that allows real time interaction between mobile clients and smart/legacy things (sensors and actuators) via a wireless gateway.

An integral aspect for designing any efficient wireless sensor network is the conservation of energy and the optimization of the power consumption. Continuous and prolonged availability of power plays a vital role in keeping the sensors energized. The power required by the sensors is largely dependent on their batteries which may require regular recharging and periodic replacement. But practically...
In Wireless sensor networks, existing energy efficient routing algorithms assumed that the sensor nodes are stationary. Some of the applications in WSN must combine with both mobile sensor nodes and fixed sensor nodes in the same networks. When mobility is functioned there should be performance degradation. Because these nodes are equipped with a lesser amount of memory, restricted battery power,...

In the convergence scenario of wireless sensor networks (WSNs) and cellular network, the mobile gateway UEs of cellular network need to provide service to larger numbers of sensor nodes, in order to reduce energy consumption and increase the network lifetime of WSNs. Nevertheless, the load balance of sensors among mobile gateways is a new- come research points in the convergence system. In this paper,...
A wireless sensor network (WSN) is a set of nodes communicating through wireless links to observe a given phenomenon. Once sensors are deployed they are considered autonomous. Their lifetime is limited by the lifetime of their batteries. Currently the mobility of sensor nodes poses the new challenges. Given the constraints of mobility and energy consumption, WSNs require the implementation of new...
This survey paper describes and classifies solutions/approaches that use Mobile Agents in Wireless Sensor Networks.
