“…For the second perspective, Lu et al [16] try to arrange the wake-up time of nodes and introduce different heuristic algorithms to reduce transmission delay. The LETED approach is proposed to solve the clock drift problem of nodes in [20], in which the nodes on the path can arrange their own transceiver time slots according to the schedules of the last hop and the next hop. The research [10] constructs broadcast tree from sink to each node and schedules the state of nodes to reduce the transmission delay.…”

To achieve the purpose of energy conservation, various sleep scheduling approaches, such as duty cycle, are applied in wireless sensor networks (WSN). However, the duty-cycle mechanism results in data delivery latency, which is critical to monitor applications. To minimize the delay caused by sleeping nodes in the transmission path, we propose to "hop over" the sleeping nodes based on the range extension of cooperative transmission (CT). The transmission delay models for the random duty-cycled WSN and optimized fixed duty-cycled WSN under cooperative operation are formulated, and an algorithm named (delay-tolerant cooperative transmission DTCT) is presented for the selection of transmission modes to avoid waiting for the sleeping nodes to wake up. The energy consumption model under direct transmission (DT) and CT mode is also presented. Theoretical analysis shows that sleep latency can be greatly reduced in the cooperative scheme, and it is validated by simulations that it outperforms the traditional store-and-forward (DT) mode in delivery latency. Especially, CT reduces 67% and 14.3% of the transmission delay in random and optimized fixed low duty-cycled WSN, respectively, and DTCT algorithm saves energy by 11.29% in random low duty-cycled WSN.

This work addresses a tough challenge of achieving two opposing goals: ensuring long lifetimes and supporting short end-to-end delays in sensor networks. Obviously, sensor nodes must wake up often to support short delays in multi-hop networks. As event occurs seldom in common applications, most wake-up are useless: nodes waste energy due to idle listening. We introduce a set of solutions, referred to as LETED (limiting end-to-end delays), which shorten the wake-up periods, reduce idle listening, and save energy. We exploit hardware features of available transceivers that allow early detection of idle wake-up periods. This feature is introduced on top of our approach to reduce idle listening stemming from clock drift owing to the estimation of run-time drift. To evaluate LETED and other MAC protocols that support short end-to-end delays we present an analytical model, which considers almost 30 hardware and software parameters. Our evaluation revealed that LETED reduces idle listening by 15x and more against similar solutions. Also, LETED outperforms other protocols and provides significant longer lifetimes. For example, nodes with LETED work 8x longer than those with a common TDMA and 2x-3x longer than with protocols based on preamble sampling, like B-MAC.

“…By controlling maximum burst transfer delay parameters of constant bit rate (CBR), hybrid offset‐time and burst assembly algorithm can effectively reduced the delay for CBR traffic .

SUMMARYThe common QoS metrics include delay, delay jitter, bandwidth guarantee, and so forth. Furthermore, the higher bandwidth requirement is also very important for some web applications, for instance, video on demand. Although QoS in networks has been well investigated during the past two decades, the existing QoS schemes usually aimed to satisfy only one QoS requirement for a particular web application. These schemes lack universality.Efficient and Fair eXplicit Congestion control Protocol (EFXCP) can achieve good network performance while maintaining low and stable queue length, which means low delay and delay jitter. In this paper, a new universal QoS scheme, E 2 FXCP, was proposed by extending EFXCP. Firstly, by utilizing the type of service field in the IP header to classify web applications into different priorities, a priority-based bandwidth allocation is implemented in E 2 FXCP, which can satisfy higher bandwidth requirement of some web applications. Secondly, by utilizing three bits in EFXCP header to mark different states of a web application with bandwidth guarantee requirement, E 2 FXCP can provide bandwidth guarantee to the web application. Simulations in Network Simulator 2 (NS2) have validated that E 2 FXCP is a universal QoS scheme, which can simultaneously satisfy multiple common QoS metrics for various web applications while maintaining good network performance.
