Recently, the vehicular sensor network (VSN) is emerging as an efficient solution for executing different sensing tasks in urban environments. However, due to the heterogeneity of vehicles in sensing capability and uncontrollable movement trajectory, it is a challenge to best provide the required quality of information (QoI) of the sensing task in VSNs. In this paper, we introduce a VSN architecture,...
This paper takes into consideration the problems related to monitoring a phenomenon of interest in an unknown and open environment using multiple mobile sensor (MS) nodes. We propose an environment learning-based phenomenon monitoring system that iteratively learns about the environment and relocates MS nodes to optimal positions, where MS nodes can attain a high weighted sensing coverage and maintain...
The task of monitoring a moving phenomenon in an unbounded area using a mobile sensor network (MSN) brings out several challenges due to the high movement speed of phenomenon, the limited sensing/communication capabilities of mobile sensor nodes. To address the challenges and achieve a high weighted sensing coverage, in this paper we propose a monitoring algorithm, namely VirFID-MP (Virtual Force...
In this paper, we study mobile sensor network (MSN) architectures and algorithms for monitoring a moving phenomenon in an unknown and open area using a group of autonomous mobile sensor (MS) nodes. Monitoring a moving phenomenon involves challenges due to limited communication/sensing ranges of MS nodes, the phenomenon’s unpredictable changes in distribution and position, and the lack of information...
In this paper, we study the problem of data gathering in wireless sensor networks using cooperative mobile elements. Due to the limit on the physical speed of mobile elements, the existing data gathering schemes that use mobile element can suffer from a high data gathering latency. To address this problem, this paper proposes a new hierarchical and cooperative data gathering architecture (HCDGA) which...
In ad hoc networks, wireless links are subject to a low quality due to time-varying channel properties, node mobility, and obstacles. Such low quality wireless links lead to the degraded performance of the end-to-end data transfer service, which also result in less applicability of ad hoc networks to practical deployment. In order to address the problem of low quality wireless links and provide a...
