End-to-End Average BER in Multihop Wireless Networks over Fading Channels

Estimating Average End-to-End Delays in IEEE 802.11 Multihop Wireless Networks

In this paper, we present a new analytic model for evaluating average end-to-end delay in IEEE 802.11 multihop wireless networks. Our model gives closed expressions for the end-to-end delay in function of arrivals and service time patterns. Each node is modeled as a M/M/1/K queue from which we can derive expressions for service time via queueing theory. By combining this delay evaluation with d...

End-to-end energy-bandwidth tradeoff in multihop wireless networks

In this paper, energy-constrained wireless multi-hop networks with a single source-destination pair are considered. A network model that incorporates both the energy radiated by the transmitter and the energy consumed by the circuits that process the signals is proposed. The rate of communication is the number of information bits transmitted (end-to-end) per coded symbol transmitted by any node...

Cognitive Multihop Wireless Sensor Networks over Nakagami-m Fading Channels

Upperbounding End-to-End Throughput of Multihop Wireless Networks

In this paper, we propose efficient algorithms to compute the upperbound of end to end throughput that are both theoretically and practically tight in multihop wireless networks.

Providing End-to-End Delay Guarantees for Multi-hop Wireless Sensor Networks over Unreliable Channels

Wireless sensor networks have been increasingly used for real-time surveillance over large areas. In such applications, it is important to support end-toend delay constraints for packet deliveries even when the corresponding flows require multi-hop transmissions. In addition to delay constraints, each flow of real-time surveillance may require some guarantees on throughput of packets that meet ...
