A metric for routing in delay-sensitive wireless sensor networks
Abstract--We present a new scheme to reduce the end-toend routing delay in the mission-critical applications of the wireless sensor networks (WSNs) under the duty cycle model. Whil...

Impact of Upper Layer Adaptation on End-to-end Delay Management in Wireless Ad Hoc Networks
A good amount of research has been developed to support QoS issues in IEEE 802.11 ad hoc networks, such as QoS routing, MAC layer QoS support, and cross-layer QoS design. However,...

Relay vs. User Cooperation in Time-Duplexed Multiaccess Networks
The performance of user-cooperation in a multi-access network is compared to that of using a wireless relay. Using the total transmit and processing power consumed at all nodes as...
