The great diversity of mobile sensor networks (MSNs) has emerged in different networks, including vehicular ad-hoc networks (VANETs), underwater sensor networks (UWSNs), and wireless body area networks (WBANs), which provide ubiquitous solutions for real-time monitoring. To prolong the network lifetime of MSNs, energy conservation for mobile sensors needs to be taken into consideration while we design...
The mobile sensor networks (MSNs) have been widely deployed to provide an ubiquitous solution for time-sensitive applications in a specific area with low deployment cost. The monitoring area of an MSN can be divided into several sensing regions (SRs). In an SR, the mobile sensor (MS) is responsible for reporting the sensed data to the sink node. For the time-sensitive applications on MSN, the time...
We focus on the coverage problem in the mobile sensor network, where each node is capable of movement. Most of the prior schemes pursue coverage by uniformizing the node density or internodal distance over the area of interest. In this paper, we first argue that the uniformizing schemes are inefficient to achieve the multi-level coverage due to the phenomenon we call geometric anomaly, and that the...
We investigate reconfiguration in large-scale mobile wireless sensor networks. Consider a field of interest (FoI) divided into sub-regions, each of which has a distinct set of sensing requirements. Consider a mobile network consisting of nodes with heterogeneous sensing capabilities distributed within the FoI. We address the problem of reconfiguring the network at minimal cost so as to satisfy all...
