Spatial query execution is an essential functionality of a sensor network, where a query gathers sensor data within a specific geographic region. Redundancy within a sensor networ...
To achieve required sensing coverage for a very long period of time is an important and challenging problem in sensor network design. Recently, Tong et al. have proposed a node rep...
Abstract— Due to the rapid growth of personal communications, it is now believed that multi-hop topologies will certainly play a key role in forthcoming wireless communications s...
