The boost of wireless technology brings dramatic growth for Vehicular ad-hoc networks(VANETs). The effective routing and forwarding protocol is critical for the performance of VANETs thus influence the automatic driving and information distribution. The dynamic characteristic of vehicle to vehicle(V2V) communications makes it hard to maintain a reliable path between vehicles. In order to improve transmission...
Low-power Wireless Networks (LWNs) have become increasingly available for mission-critical applications such as security surveillance and disaster response. In particular, emerging low-power wireless audio platforms provide an economical solution for ad hoc voice communication in emergency scenarios. In this paper, we develop a system called Adaptive Stream Multicast (ASM) for voice communication...
In this paper, the performance of network coding in underwater acoustic networks is evaluated. The objective of this study is to determine the suitability of using network coding for error recovery in the high error rate underwater acoustic channel; and if so, what parameter settings should be used for a given network so that it can achieve the desired performance. Our study of network coding is conducted...
Providing efficient networking services in MANETs is very challenging in presence of mobility, unpredictable radio channel and interference: a significant number of packets can be corrupted and/or lost. To increase reliability, various measures have been proposed. A popular approach is to use multiple paths and transmit identical copies of the packet on each path (i.e., path redundancy). A more efficient...
We propose a protocol for a distributed sensor network of unreliable components that causes the network to behave collectively as a memory device. The reliability of this memory device is greater than that of the individual components. Nodes with redundant data are not spatially collocated, so the system is robust to spatially localized damage. Address-datum pairs are submitted to the network at a...
