In this paper, we explore the use of partially overlapped channels in wireless mesh networks that consist of multiple 802.11-based access points. We propose novel channel allocation and link scheduling algorithms in the MAC layer to enhance network performance. Due to different traffic characteristics in multi-hop WMNs compared to those in one-hop 802.11 networks, we perform our optimization based...
In this paper, we propose an improved resource reservation algorithm ESRPT (enhanced shortest remaining processing time) for bursty traffic based on IEEE 802.15.3 standard. In this algorithm, each transmitter reports current fragments number of the first MSDU (MAC service data unit) and all of the fragments number of the remainder MSDUs in the pending transmission queue to PNC (piconet coordinator)...
IEEE 802.15.3 high-rate wireless personal area network (WPAN) has been emerged in order to support quality of service (QoS) for real-time multimedia traffic and high data rate wireless connectivity. In IEEE 802.15.3 MAC, TDMA is used to achieve channel scheduling. It's a crucial issue to effectively allocate channel time for each stream during every superframe for multimedia services. This paper proposes...
