Abnormal traffic detection is important to network management. This paper aims at the characteristic of multi-hop network, and defines abnormity that traffic-burst after failure. Then the paper presents a fast auto-adaptive traffic-aware abnormal detection method. This method compresses data via efficient histogram, and detects double-size bursts via congregate function. We analyze the status of links...
Multihop wireless backhual networks are emerging as a cost-effective solution to provide ubiquitous and broadband access to meet the rapidly increasing demands of multimedia applications. In this paper, we consider the joint optimal design of routing, medium access control (MAC) scheduling and physical layer resource allocation for such networks, where beamforming antenna arrays are equipped at the...
The IEEE 802.16 standard, also known as WiMax, provides a mechanism for deploying high-speed wireless mesh network in metropolitan areas. In this paper, we propose an algorithm for the data sub-channel allocation, i.e., transmission scheduling, of WiMax based mesh networks. The goal is to increase spatial reuse, achieve high system throughput, and provide fair access for the subscriber stations. In...
