Conventionally, diplexers are designed by connecting two filters of different frequencies using a transmission T-line junction which acts as distribution network serving the individual filters. Here, novel diplexer has been proposed and to utilize directly coupled resonator network. The is square open-loop resonators same resonant frequency 1.95 GHz. Coupling achieved ?/4 line couple them. This...

IEEE802.11s draft proposes a new medium access control (MAC) function-mesh deterministic access (MDA), which is mainly used for single-channel wireless mesh local area network (LAN). In single-channel environment, collisions between control packets and data packets may occur very often. In order to provide higher performance and network capacity for wireless mesh LAN, this article develops an a...

Channel assignment has been extensively studied in wireless network such as cellular network, with the appearance of the new multi-radio multi-channel network such as wireless mesh network and cognitive radio network, channel assignment in such network has been a hot research topic again. In this paper, we use game theory to study the channel assignment problem, we model channel assignment in m...

Consumer behaviour at pure Internet players has been analysed thoroughly in earlier work. When it comes to retailers with multiple distribution channels, however, new behaviour patterns can be observed. Given the fact that multi-channel retailing is much more common than Internet-only, the analysis of consumer behaviour in a multi-channel context constitutes a challenge for the deeper understan...

The use of multiple channels for transmissions has raised several challenges, for example, multi-channel hidden terminal problem, channel switching delay, and control channel saturation problem. Dedicated control channel techniques simplify channel coordination by eliminating the need for synchronization, however the control channel may become the bottleneck for the performance of the network. ...

Medium Access Control(MAC) protocol is quite important to the performance of underwater sensor networks(UWSNs). Recently, much research work has been done on the design of new MAC protocols for UWSNs to improve throughput and energy efficiency [1]–[3]. All these work is for the singlechannel network scenario. However, the fast development of underwater acoustic communication technologies enable...
