With the popularization of human-carried devices, it is possible for Mobile Crowd Sensing (MCS) applications to perform large scale sensing with sensors embedded in these devices. Many incentive mechanisms for MCS applications have been proposed due to the importance of attracting more worker to participate. However, these mechanisms failed to consider situations where there are constraints on both...
Localization technology based on received signal strength indication (RSSI) is a low cost and low complexity technology, and it is widely applied in distance-based localization of wireless sensor networks (WSNs). The error of existed localization technologies is great. This paper presents an N-times trilateral centroid weighted localization algorithm (NTCWLA), which reduces the error greatly. Considering...
In the replacing market, diffusion of information product is influenced by users' interaction and cooperating function between the complementary software and hardware. Therefore, this paper creates the direct network effect function which is based on the interpersonal relationship, and the indirect network effect function which is composed by the utility of the software and hardware. Based on the...
This paper presents fundamental results for the problem of throughput optimization in heterogeneous mobile sensor networks by considering the penalty incurred when a mobile node switches to another receiver. We present online and offline algorithms determining which receiver each mobile node connects to at each time slot to maximize total throughput. We initially consider the network setup with a...
As sensor technology advances, the availability of high resolution data and complex sensor readings become more commonplace, and the range of potential sensor network applications, accuracy, and data collection efforts expands. As a result, there is an increased need for tiered sensor network architectures and energy efficient data collection mechanisms in order to maintain network feasibility and...
Resource replication has been emerging as one of the most widely studied phenomena in a distributed environment. In this paper, we propose a novel distributed approach, named MetroReplica, to achieve the global optimized resource replication. MetroReplica is a Markov Chain Mote Carlo sampling algorithm based on the metropolis-hastings algorithm, which never employ the global information but a replication...
In traditional routing protocols for mobile ad hoc networks (MANETs), it costs highly to rebuild routes by flooding query messages again and again over the whole network. A novel routing protocol for MANETs, incremental recoverable routing (IRR) Protocol, is proposed in this paper. Unlike the previous protocols, nodes in IRR perform routing discovery and maintenance based on the use of the process...
Due to the imitated power supply in MANETs, the power consumption must be taken into account for a design of the resource discovery approach. In this paper, we proposed a distributed energy-aware resource discover approach, named EaDiscovery, to perform energy-efficient resource discovery. The motivation of the proposed approach is to minimize the total power consumption to request a service or subscribe...
Due to high mobility, highly dynamic topology and unreliable communication medium of Mobile Ad Hoc Networks (MANETs), nodes mobility must be taken into account in design of a service discovery protocol for such environment. A novel approach, Mobility-aware Attenuated Bloom Filters (maBF), to perform effective and efficient service discovery in MANETs is proposed in this paper. In order to guarantee...
In this paper, we propose a hybrid mobile communication approach rendered for the use in remote monitoring system. Based on the various mature, commercial and low cost mobile communication networks, the proposed technique can scheme multiple mobile communication modes and links. Since the protocol is open, general and extensible, functions are divided into three layers, i.e., application layer, data...
