Human mobility is known to follow simple reproducible patterns, i.e., humans tend to travel a few known places. Early detection of those “significant journeys” has a prospect for emerging smart applications like real-time traffic route recommendation and automated HVAC (heating, ventilating, and air conditioning) systems. In this paper, we design, implement, and evaluate a mobile system that effectively...
Nowadays, vehicles have shown great potential in crowdsensing. To guarantee a good Quality of Service (QoS), stimulating enough vehicles to participate in crowdsensing is very necessary. In this paper, we focus on the incentive mechanism design in the vehicle-based nondeterministic crowdsensing. Different from existing works, we take into consideration that each vehicle performs sensing tasks along...
Below the Media Access Control (MAC) layer is the Physical (PHY) layer which deals with the actual transmission of the bits received from the MAC layer above into electromagnetic signals. This layer is optimized to implore power management in wireless networks. Power management is a crucial issue in wireless and mobile networks.

In order to roam in 3G/WiMAX networks seamlessly, a fuzzy neural network access selection algorithm optimized on the basis of ant colony optimization (ACO) algorithm is put forward. The proposed algorithm takes radio signal strength,...

In this article we propose a hybrid heuristic algorithm able...
Unconventional public transportations are quite different than those which are conventional, as the navigation routes and path finding algorithms may vary. In the case of mini buses in Indonesia, the current navigation system especially online and mobile-based has not been adequate. Therefore, this paper is proposed to introduce an algorithm design that illustrates and routes for a path based on best...

In this paper we present a set of activity recognition and localization algorithms that together assemble a large amount of information about activities on a parking lot. The aim is to detect and recognize events that may pose a threat to truck drivers and trucks. The algorithms perform zone-based activity learning, individual action recognition and group detection. Visual sensor data, from one camera,...
We consider the task of providing communication coverage to a group of sensing robots (sensors) moving independently to collect data. We provide communication via controlled placement of router vehicles that relay messages from any sensor to any other sensor in the system under the assumptions of 1) no cooperation from the sensors, and 2) only sensor-router or router-router communication over a maximum...
The forthcoming Intelligent Transportation System aims to achieve safety and productivity in transportation using vehicular ad hoc networks (VANETs) to support the communications system required. Currently, some clustering approaches have been proposed to improve the performance of VANETs due to their dynamic nature, high scalability and load balancing results. However, the host mobility and the constantly...
Efficient data delivery is a great challenge in vehicular networks because of frequent network disruption, fast topological change and mobility uncertainty. The vehicular trajectory knowledge plays a key role in data delivery. Existing algorithms have largely made predictions on the trajectory with coarse-grained patterns such as spatial distribution or/and the inter-meeting time distribution, which...
In this paper we propose a direction based clustering algorithm to disseminate the information amongst vehicles. This protocol can be used to realize efficiency applications in VANETs such as adaptive traffic signal control by estimating the density of vehicles on a given road. C-DRIVE uses the direction of the vehicle to optimize the data dissemination during the formation of the clusters and hence...

This protocol is used to estimate the density of vehicles on a given road. As in any clustering algorithm,...
Selecting optimal routes to reduce travel time has been an important research area for urban traffic network managements. Various parameters such as route length, average speed and event situations need to be considered in the design of a route guidance system. In this paper, we develop a new navigation system based on the combination of fastest path search algorithm and travel time prediction method...
A novel technique by which wireless devices such as sensor nodes can deduce their own mobility status,based on analysis of patterns in their local neighbourhood, is described.For many systems in which a neighbour table is maintained through regular status messages or other interaction, the technique incurs no additional communication overhead. The technique does not require that nodes have additional...
Wireless mesh network (WMN) has become a popular access network architecture. But because of its multi-hop nature, co-channel interference and contention, the attainable capacity of a wireless node in a WMN is significantly less than the radio capacity. We propose a overlay architecture for a WMN, where a wireless-ring (WRing) is deployed over the regular mesh for carrying wireless mesh traffic only...
