In this paper, the author firstly analyzes the limitations of the existing short-range networks, and then proposes a new wireless network protocol and puts forward my own view on system architecture, network topology, wireless channel competition algorithm and multi-path selection algorithm, finally presents hardware and software design block diagram of wireless node. The application performances...
The capacity of wireless networks is greatly affected by the available information on network states, such as network topology, channel state, and traffic information. Previous research has estimated the capacity of wireless networks by assuming that each node in the network can obtain precise network information. However, in reality, precise network information may not be readily available, and it...
The receiver capacity model is a simple model to capture flow dynamics in a multi-hop wireless network, by presenting linear constraints to define the feasible rate region of the network, taking into account interference. The model associates with each receiver in the network a notion of constant receiver capacity. Receiver capacity is defined as the maximum possible sum rate of all flows that the...
IEEE 802.15.4 is a protocol for low-rate wireless personal area networks. It contains two topologies: the star topology and the peer-to-peer topology. It has good performances for the star topology. However, the beacon collisions with other beacons, data or control frames make the multi-hop beacon-enabled mode difficult to be built and maintained. Although nonbeacon-enabled has better performance,...
