While a wireless sensor network is deployed to monitor certain events and pinpoint their locations, the location information is intended only for legitimate users. However, an eav...
We address the problem of estimating the remaining energy of a node battery in wireless sensor networks. To solve this issue, we provide an on-line battery model that requires lim...
This paper investigates the energy-saving organization of sensor nodes in large wireless sensor networks. Due to a random deployment used in many application scenarios, much more n...
