In this paper, we design and implement a reliable data processing and analysis test bed (NESCTB) for wireless sensor networks (WSNs). It contains 36 wireless sensor nodes connected through Ethernet to a central server so that, with web interface, remote users are able to schedule tasks and monitor the nodes' operations online. In addition, reprogramming and data logging can also be provided via the wired network. Powerful data processing and analysis tools are developed for information searching and processing, real-time topology visualization, 2-D and 3-D viewing of statistical diagrams, snapshots and timing sequences. The tools can significantly improve user-friendliness and operability of the test bed. The application scenarios of the test bed are discussed and a validation experiment for the referred application case NESCSurge demonstrates the convenience and effectiveness of NESCTB. © 2011 IEEE.

In a heterogeneous network environment, constructing applications of remote distributed intelligent transportation system (ITS) are faced with complex communication problems proposed by online management, data acquisition and the coordination control of traffic node devices. Therefore, a framework based on SIP/ZigBee architecture is proposed. By using SIP and its extensions, a seamless convergence of traffic measurement and control network between the Internet and a short-range wireless sensor and actuator networks (WSAN) can be achieved. The application result shows that various remote communications and control operations of ITS distributed nodes can be unified and simplified. © 2011 IEEE.

Raptor code, a member of the rateless fountain codes family, has been a preferred technology for the forward error correction (FEC) at the application layer. It is used by the 3(rd) Generation Partnership Program (3GPP) Multimedia Broadcast/Multicast Service (MBMS) and Digital Video Broadcasting (DVB-H) standards for multimedia broadcast and content delivery. Currently, a next generation fountain code, called RaptorQ, is being proposed. It aims at reducing to a minimum the redundant FEC information, outperforming significantly Raptor code. The improved coding performance comes at the expense of increased encoding and decoding complexity. This paper compares the coding properties, the decoding performance and the energy efficiency of the two codes on embedded system. Furthermore, simulations are performed for a practical MBMS scenario. Finally, conclusions are drawn with respect to the applicability of the new code for realtime multimedia broadcasting and content delivery.

sensor networks are a sensing, computing and communication infrastructure that are able to observe and respond to phenomena in the natural environment and in our physical and cyber infrastructure. In this paper, we propose a sensor network with mobile and static sensor nodes set-up for performing tasks like sensing a phenomenon or monitoring a region. We investigate how the sensor network performs in the case when the sensor nodes move. We compare the simulation results for two cases: the sensor network with stationary sensor nodes and multi mobile sensor nodes. The simulation results have shown that for the multi mobile sensors, the goodput is unstable. The goodput of stationary sensors is better than multi mobile sensors, but the consumed energy of multi mobile sensors is better than stationary sensors. © 2011 IEEE.

This paper works on the participatory sensing in the area of sensor network. One of the most important challenges in participatory sensing is selecting the participants to collect their sensed data to monitor the environment. The goal here is to obtain the data of high quality with low payment from a predefined number of participants. To achieve the goal, this paper proposes a novel approach using the techniques of evolutionary algorithm. It models the goal as a multi-objective Knapsack problem, which is resolved by the hybrid scheme of Univariate Model Distribution Algorithm (UDMA) and the enhanced Third Evolution step of Generalized Differential Evolution (EGDE3). The experiment results show the effectiveness of the proposed approach in terms of the ratio of the payment and data quality, and takeover time compared with the Genetic Algorithm (GA) and Reverse Auction based Dynamic Price (RADP) scheme. © 2011 IEEE.

Extensive data generated by peers of nodes in wireless sensor networks (WSNs) needs to be analysed and processed in order to extract information that is meaningful to the user. Data processing techniques that achieve this goal on sensor nodes are required to operate while meeting resource constraints such as memory and power to prolong a sensor network's lifetime. This survey serves to provide a comprehensive examination of such techniques, enabling developers of WSN applications to select and implement data processing techniques that perform efficiently for their intended WSN application. It presents a general analysis of the issue of energy conservation in sensor networks and an up-to-date classification and evaluation of data processing techniques that have factored in energy constraints of sensors. © 2011 Springer-Verlag Berlin Heidelberg.

This paper presented a fast fasten control algorithm (2FCA) in wireless sensor networks for information processing and transmitting. Using anycast technology, 2FCA can fast fasten broken routing path, which will decrease failure delay and increase packets' success rate. In the algorithm, it restricts participant nodes to save scarce energy and bandwidth resource, and then prolongs network's lifetime and improve the networks' performance. The paper also proposed the mathematical analysis and get the conclusion that 2FCA has a lower message complexity than AODV. Finally, in computer simulation, rerouting overhead and delay are computed with different algorithm, the results congruously showed that 2FCA algorithm is feasible and preferable in wireless sensor networks.
