Packet level coding schemes are used to improve the transmission reliability and efficiency in data broadcasting applications, especially for wireless networks. However, existing coding schemes have large redundancy for packets are coded by a random way or some certain probability distributions. Although the Maximum Distance Separable (MDS) codes are designed without redundancy, they are not effective...
The link scheduling in wireless multi-hop networks is addressed. Different from most of work that adopt the protocol interference model which merely take consideration of packet collisions, our proposed algorithms use the physical interference model to reflect the aggregated signal to interference and noise ratio (SINR), which is a more accurate abstraction of the real scenario. We first propose a...
Many previous schemes of multi-node cooperation mimic the behavior of the multiple-antenna system, and the imitation usually causes extra overheads. In this paper, we propose a novel multi-node cooperation scheme to avoid the imitation. The basic idea is to take the wireless broadcast advantage in the whole procedure. As a result, each source could maintain a multihop diversity route to the destination...
Probe-vehicle technique is an effective method of collecting real-time traffic information on road networks. A technically feasible and cost-effective wireless communication network is in great demand so that large amounts of traffic data sampled by probe vehicles over a large geographical area can be sent to the traffic management center (TMC). However, how to design such a wireless network forms...
