In this paper, we introduce a priority based SIP server scheduling mechanism in which the original incoming SIP requests have strict priority over the retransmitted requests. The proposed mechanism provides the network administrator with the ability to configure the buffer size of a SIP server to a moderately high value without causing the server crash due to retransmissions. A new field on the SIP...
WSNs hold the promise of many new applications that require the network to handle traffic with different priority levels and QoS requirement in an energy efficient way while avoiding collisions and interference. In this paper, we investigate several aspects related to the application requirements and the network states and resources in order to provide multi-QoS routing protocol for WSNs. We propose...
A distinguishing feature of the universal mobile telecommunications system (UMTS) is the support of different levels of quality of service (QoS) as required by subscribers and their applications. To provide QoS, the UMTS backbone network needs an efficient QoS mechanism to provide the demanded level of services on UMTS network. A model to investigate end-to-end quality of service (QoS) provisioning...
