In this paper, we first challenge the accuracy of the so-called innovative assumption that is widely adopted in delay performance analysis of network-coding-based epidemic routing (NCER) in delay-tolerant networks (DTNs). We demonstrate that this optimistic assumption severely underestimates data delivery delay and solves this problem successfully by introducing an extra encounter factor $\delta$...
Wireless sensor networks (WSNs) may consist of hundreds or thousands of low-cost sensors, which makes it difficult for a central fusion center to oversee every sensor node. In this paper, we are interested in the problem of signal detection using WSNs. We propose a distributed framework for cross-layer design which is not only suitable to such application, but scalable with respect to the network...
