In this paper we investigate a practical routing solution for a new class of wireless sensor networks where any node can be mobile anytime. Assuming GPS-enabled sensor nodes we pro...
To allow for an efficient usage of a device in pervasive computing environments, reliable and yet convenient user access is an important requirement. The problem becomes more comp...
One of the challenges in pervasive computing is communication between a mobile user's terminal and the continuously changing local environment. Bluetooth is one potential opt...
Abstract—Recent advances in the technology of wireless electronic devices have made possible to build ad–hoc Wireless Sensor Networks (WSNs) using inexpensive nodes consisting ...
