In data center networks, many network-intensive applications leverage large fan-in and many-to-one communication to achieve high performance. However, the special traffic patterns, such as micro-burst and high concurrency, easily cause TCP Incast problem and seriously degrade the application performance. To address the TCP Incast problem, we first reveal theoretically and empirically that alleviating...
In heterogeneous sensor networks (HSNs), which use existing key predistribution schemes, network security will significantly decline with time. In this paper, a continuous secure scheme is proposed based on two-dimensional backward key chains. In the scheme, powerful sensors do not need to be equipped with tamper-resistant hardware. Analysis and simulations indicate that the proposed scheme can significantly...
In this paper we perform some probabilistic analysis on state reachabilities of wireless lossy channel systems (WLCS) using Continuous Stochastic Logic (CSL) for Quasi Birth-Death model (QBD). To study WLCS in a continuous time setting, we first extend Probabilistic Lossy Channel Systems (PLCS) towards WLCS. We show that the state set S0 is an attractor of WLCS model, and discuss the accumulated steady-state...
In wireless LAN connected with Internet, the anomaly of wireless channel and the greedy nature of closed loop control in TCP lead to the congestion problem and significant unfair bandwidth distribution between TCP flows. In this paper, an ECN-based access point congestion control algorithm called APCC (AP congestion control) is proposed. The main properties of APCC are: (1) Using both wireless channel...
Many of packet loss as a result of factors other than congestion impact the performance of TCP in wired/wirelss hybrid networks. Firstly, this paper proposes one concept of congestion probability (CP) and analyzes the correlation of CP and network state. Then a transport control protocol named as TCP-PCP is proposed, which is based on the prediction of congestion probability instead of single loss...
A distributed algorithm called P-REMiT is proposed for building an energy-efficient multicast tree in ad hoc networks. The P-REMiT uses the probability method to balance the total energy consumption (TEC) and system lifetime (SL) of multicast tree. It gets the better performance than S-REMiT on metrics about system life and also obtains the better performance than L-REMiT on metrics about TEC. It...
