Application which combines intelligent terminals based on Android platform with sensor network is developing faster and faster. In order to achieve the Android terminal's controlling hardware sensors through wireless net, the subject realizes a USB Accessory Mode + ZigBee data communication mode by the way of research, comparison and scientific experiment of combining Android platform with wireless...
Many existing routing protocols for wireless mesh networks (WMNs) are based on minimal hop counts and cannot fit WMNs because they did not take into account congestions in networks. Although other multipath routing protocols use node- or link-disjoint routes, they are still based on minimal hop counts and may even cause extra congestion into networks. This is because a node-disjoint path may contain...
WiMedia ultra wideband (UWB) MAC consists of distributed reservation protocol (DRP) and prioritized contention access (PCA), where DRP is used to reserve the medium for time division multiple access for isochronous and other traffic. This paper proposes an improved service interval-based medium access slot (MAS) allocation (ISIMA) algorithm for MAS allocation to support the quality of service (QoS)...
Capacity based topology management is essential for a wireless ad hoc network due to its limited capacity so that topology control becomes indispensable to deploy large wireless ad hoc networks. This paper discusses the impact of topology control on network capacity by introducing a new definition of the expected capacity that is first analyzed in the perspective of cross layer optimization. Based...
