Fair resource allocation is usually studied in a static context, in which a fixed amount of resources is to be shared. In dynamic resource allocation one usually tries to assign resources instantaneously so that the average share of each user is split fairly. The exact definition of the average share may depend on the application, as different applications may require averaging over different time...
In this paper, we present fast converging algorithms that fit well WiMAX mesh networks. First, a centralized scheduling algorithm is presented. It calculates schedules by transforming the multi-hop tree into a single hop, and then repartitioning the different schedules in the multi-hop tree. Second, a routing metric called Multiple Channel One Pass (MCOP) is introduced. MCOP chooses routes by explicitly...
Orthogonal Frequency Division Multiple Access (OFDMA) is one of the most promising, demanded and researched modulation and access methods for future mobile wireless networks. Emerging technologies, like Worldwide Interoperability for Microwave Access (WiMAX) or Long Term Evolution (LTE), are adopting OFDMA due to its high spectral efficiency, scalability for high amounts of users and mobility support...
Providing end-to-end delay bound for real-time applications is a major challenge in wireless mesh networks (WMNs) because the bandwidth requirements of flows are time-varied and the channel condition is unstable due to the wireless interference between the links. In this paper, we present a two-stage slot allocation mechanism in TDMA-based WMNs. First, we assume that the bandwidth requirement of each...
