This paper presents a new routing protocol named RACE (network conditions Aware geographical forwarding protocol for real-time applications in mobile wireless sensor networks) that was developed to address the challenges found while using WSNs in a running competition scenario: QoS, mobility, and high workload. RACE aims to provide QoS requirements to the application layer by giving priority to real-time...
Alerts correlation techniques have been widely used to provide intelligent and stateful detection methodologies. This is to understand attack steps and predict the expected sequence of events. However, most of the proposed systems are based on rule - based mechanisms which are tedious and error prone. Other methods are based on statistical modeling, these are unable to identify causal relationships...
IEEE 802.15.4 is a global standard designed for emerging applications in low-rate wireless personal area networks (LR-WPANs). The standard provides nice features such as a beacon-enabled mode and guaranteed time slots for real-time data delivery. However, how to optimally operate those features is still an open issue. For the optimal operation of the features, this paper proposes a holistic optimization...
DCCP is proposed to replace UDP for its ability of congestion control while maintaining its promptness by ignoring lost packets as UDP does. The network would suffer less congestion. However, whether the applications that switch from UDP to DCCP can maintain their needed performance or not is a big question. This paper investigates this problem by evaluating DCCP based VoIP vs. a variety of TCPs using...
