The evaluation of QoS requirements is one of the critical functions that span both the design and the run-time phases of QoS management. This paper presents an architecture for Qo...
Some sensor applications are interested in collecting data from multiple regions. For supporting such applications with multiple target regions, most conventional protocols are bas...
Sensor networks have recently gained popularity for a wide spectrum of applications. When performing monitoring tasks in hostile environments, security requirements become critical...
In this paper we develop an analytical threshold-based bandwidth allocation policy for 3G multi-class cellular networks. We consider the effects of user mobility when the cellular...
Multicast/broadcast is an important service primitive in networks. The IEEE 802.11 multicast/broadcast protocol is based on the basic access procedure of Carrier Sense Multiple Ac...
