Understanding packet loss patterns in Internet Protocol (IP) networks is important for achieving the desired quality of service in multimedia transfers. In this paper, we study the loss patterns in video transfers using User Datagram Protocol (UDP) in a congested packet network. We use trace-driven ns-2 simulations to collect packet loss traces in networks, and we apply wavelet analysis to inve...

Congestions in wireless sensor networks (WSNs) could potentially cause packet loss, throughput impairment and energy waste. To address this issue, a hop-by-hop crosslayer congestion control scheme (HCCC) built on contention-based MAC protocol is proposed in this paper. According to MAC-layer channel information including buffer occupancy ratio and congestion degree of local node, HCCC dynamical...

Understanding packet loss patterns in IP networks is important for achieving the desired quality of service in multimedia transfers. In this paper, we study the loss patterns in video transfers over UDP in a congested packet network. We use wavelet analysis to investigate the behavior of packet loss on various timescales. We show that time scales are essential for understanding loss behavior an...

Many user applications (and the transport protocols that make them possible) require two-way communications. To assess this capability, and to achieve test system simplicity, round-trip loss measurements are frequently conducted in practice. The Two-Way Active Measurement Protocol specified in RFC 5357 establishes a round-trip loss measurement capability for the Internet. However, there is curr...

Generic purpose multi-core PC architectures are facing performance challenges of high rate packet reception on gigabit per second and higher speed network interfaces. In order to assign a CPU core to a networking softIRQ, the single input queue design of the low-level packet processing subsystem relies on the kernel's Symmetric Multiprocessing (SMP) scheduler, which does not perform load balanc...

The primary objective of event driven wireless sensor networks is to route the detected or monitored data at the earliest to the base station depending on their degree of priority since the data generated in a sensor network has different importance. In order to avoid indiscriminate dropping of data during congestion we propose a novel congestion protocol named priority based congestion detecti...

This paper proposes a transmission scheduling algorithm for interference management in broadband wireless access networks. The algorithm aims at minimizing the cochannel interference using basestation coordination while still maintaining the other quality of service (QoS) requirements such as packet delay, throughput, and packet loss. The interference reduction is achieved by avoiding (or minim...

a cochlear implant is an implanted electronic device used to provide a sensation of hearing to a person who is hard of hearing. the cochlear implant is often referred to as a bionic ear. this paper presents an undecimated wavelet‑based speech coding strategy for cochlear implants, which gives a novel speech processor. the undecimated wavelet packet transform (uwpt) is computed like the wavelet ...
