In this paper, we study the problem of supporting multicast traffic in wireless sensor networks with network coding. On one hand, coding operations can reduce power consumption and consequently improve the network lifetime. On the other hand, performing network coding requires the use of the limited resources of the sensor nodes such as memory and energy. We study the tradeoff between maximizing the...
In wireless networks, transmissions can generally be overheard by unintended nodes in the vicinity of the sender and receiver, potentially causing interference to their own communications. Much of the related research has considered this as a nuisance and resulted in various proposals for overcoming the interference using scheduling, channel assignment, and many other mechanisms. In recent years,...
The following topics are dealt with: OFDM/MIMO; multimedia networking and broadband access; traffic modeling and analysis; network design and localization; radio resource management and QoS provisioning; wireless networks; ad hoc networks; hardware design and coding; network security and cognitive radios; sensor networks.
We devise an adaptive fault-tolerant scheme based on the exponentially weighted moving average (EWMA) which can provide fault tolerant in sensor networks and balance between traffic overhead and transmission failure. We use the multipath routing to transmit packets, and according to wireless network environments we adaptively change the required number of paths for transmission. So it can achieve...
Due to the limitation of wireless communication capacity, a camera sensor network will be easily congested and the perceived video quality considerably deteriorates, when all nodes generate and transmit high-quality video data. To tackle this problem, taking into account that not all video data are equally important from a viewpoint of surveillance or observation applications, our research group proposes...
