Routing is one of the most challenging open problems in disruption-tolerant networks (DTNs) because of the shortlived wireless connectivity environment. To deal with this issue, r...
Wireless Sensor Networks (WSNs) provide an important means of monitoring the physical world, but their ons present challenges to fundamental network services such as routing. In t...

Routing in multi-hop wireless networks is typically greedy, with every connection attempting to establish a path that minimizes its number of hops. However, interference plays a m...
Using directional antennas in wireless ad hoc networks is an attractive issue due to its potential advantages such as spatial reuse, low power consumption and low chance of interfe...
—Spatial query execution is an essential functionality of a sensor network. Redundancy within a sensor network can be exploited to reduce the communication cost incurred in execu...
