Abstract— Health monitoring based on the internet of things (IoT) and cloud computing is regarded as a hot topic to research. However, such systems often face issues with delay throughput due large amount data that must be transmitted from sensors cloud. One important type for health Electrocardiogram (ECG) signals, which generate transmitted. This research treats this problem by modelling thes...

The demand for fast transfer of large volumes of data, and the deployment of the network infrastructures is ever increasing. However, the dominant transport protocol of today, TCP, does not meet this demand because it favors reliability over timeliness and fails to fully utilize the network capacity due to limitations of its conservative congestion control algorithm. The slow response of TCP in...

The quality of service limitation of today’s Internet is a major challenge for real-time voice communications. Excessive delay, packet loss, and high delay jitter all impair the communication quality. A new receiver-based playout scheduling scheme is proposed to improve the tradeoff between buffering delay and late loss for real-time voice communication over IP networks. In this scheme the netw...

VoIPs, emerging technologies, offer high-quality, real-time voice services over IP-based broadband networks. Perceived voice quality is a key metric for VoIP applications that is mainly affected by IP network impairments such as delay, jitter, and packet loss. Playout buffers at the receiving end can compensate for the effects of jitter based on a tradeoff between delay and loss. Adaptive smoot...

In order to transfer voice or some other application requiring real-time delivery over a packet network, we need a de-jitter buffer to eliminate delay jitters. An important design parameter is the depth of the de-jitter buffer since it influences two important parameters controlling voice quality, namely voice-path delay and packet loss probability. In this paper, we propose and study several s...

Advances in low-power electronics design and wireless communication have enabled the development of low cost, low power micro-sensor nodes. These sensor nodes are capable of sensing, processing and forwarding which have many applications such as underwater networks. In underwater wireless sensor networks (UWSNs) applications, sensors which are placed in underwater environments and predicted ena...
