Distributed stream processing relies on in-network operator placement to achieve an optimal resource allocation which can use the pool of machines and network resource efficiently. Due to the QoS (Quality of Service) constraints imposed by the application, operator placement is usually treated as an optimization problem with constraints. Trying to get a global optimization is challenging since it's...
The latest version of IEEE 802.11s draft proposes a simple hop-by-hop congestion control framework without the specific algorithm for congestion detection and local rate control. This paper presents a dynamic pricing policy and new rate control model based congestion control scheme which works at the data link layer (DLL) over IEEE 802.11s draft. We introduce dynamic pricing function as one of the...
This paper presents a bandwidth occupied time proportion fair MAC algorithm (BOTP-FMAC) for WLAN and wireless mesh network (WMN). It aims to address the unfairness problem in enhanced distributed channel access (EDCA) mechanism, in which higher-priority streaming traffic flows intend to severely deprive the access opportunity of lower-priority traffic flows due to the capture effect, especially when...
