We present a new type of monotone submodular functions: multi-peak submodular functions. Roughly speaking, given a family of sets F, we construct a monotone submodular function f ...
Abstract— We investigate the secure connectivity of wireless sensor networks under the pairwise key distribution scheme of Chan et al.. Unlike recent work which was carried out u...
Streaming media is pervasive on the Internet now and is continuing to grow rapidly. Most streaming media systems have adopted the model of broadcast. Unfortunately, the nature of ...
Abstract: Wireless sensor networks are often based on omni-sensing and communication models. In contrast, in this paper, we investigate sensor networks with directional sensing and...
Abstract. We present the discrete beeping communication model, which assumes nodes have minimal knowledge about their environment and severely limited communication capabilities. S...
There has been extensive research focused on maximizing the throughput of wireless networks in general and mesh networks in particular. Recently, techniques have been developed th...
The ability to incorporate low-power, wireless communication into embedded devices gives rise to a new genre of embedded software that is distributed, dynamic, and adaptive. This p...

This paper addresses the problem of pay-as-you-watch services over unicast and multicast communications. For each communication model, we present two solutions, non-verifiable and...
Abstract. HeteroMPI is an extension of MPI designed for high performance computing on heterogeneous networks of computers. The recent new feature of HeteroMPI is the optimized vers...
