The coverage problem in a wireless sensor network
One fundamental issue in sensor networks is the coverage problem, which reflects how well a sensor network is monitored or tracked by sensors. In this paper, we formulate this pr...

A link-indexed statistical traffic prediction approach to improving IEEE 802.11 PSM
Power management is an important technique to prolong the lifetime of battery-powered wireless ad hoc networks. The fact that the energy consumed in the idle state dominates the t...

PreDA: Predicate Routing for DTN Architectures over MANET
—We consider a Delay Tolerant Network (DTN) whose users (nodes) are connected by an underlying Mobile Ad hoc Network (MANET) substrate. Users can declaratively express high-level...

SECTOR: secure tracking of node encounters in multi-hop wireless networks
In this paper we present SECTOR, a set of mechanisms for the secure verification of the time of encounters between nodes in multi-hop wireless networks. This information can be u...

Exploiting heterogeneity in sensor networks
—The presence of heterogeneous nodes (i.e., nodes with an enhanced energy capacity or communication capability) in a sensor network is known to increase network reliability and l...
