A peer-to-peer(P2P) system comprises a network of nodes that are capable of sharing and exchanging resources with one another. Recent studies of P2P networks show that many resour...
Abstract—We target a two-tier sensor network with resourcerich master nodes at the upper tier and resource-poor sensor nodes at the lower tier. Master nodes collect data from sen...
Abstract. The event-condition-action (ECA) paradigm holds enormous potential in pervasive computing environments. However, the problem of reliable delivery of event data, generated...
Mobile ad-hoc networks (MANETs) are failure-prone environments; it is common for mobile wireless nodes to intermittently disconnect from the network, e.g., due to signal blockage....
— In reliable multicast, data packets can be cached at some nodes such as repair servers for future possible retransmission in loss recovery schemes. How to cache packets to opti...
