Peer-to-peer (P2P) data networks dominate Internet traffic. In this work, we study the problems that arise when mobile hosts participate in P2P networks. We primarily focus on the performance issues as experienced by the mobile host, but also study the impact on other fixed peers. Using Bit Torrent as a key example, we identify several unique problems that(More)
In this paper we present a new approach called cue-based networking that uses hints or cues about the physical environment to optimize networked application behavior. We define the notion of cues and describe how cues can be obtained using a wireless sensor network as the underlying platform. We identify both the research and system challenges that need to(More)
For large-scale Wireless Sensor Networks(WSNs), cluster-based architecture is desirable. Conventional short range sensor radio, however, is often inefficient for the inter-cluster communication due to the large distance between cluster heads. One solution is to use a longer range radio for inter-cluster head communication. In this paper, we consider a(More)
