Plan timing and location of marketing.
Measurements have been made for various frequency bandwidths, center frequencies, and locations of the point force.
Context information includes the network connectivity (such as bandwidth and delay), location, user preferences, time, etc.
Even if wireless errors disrupt the data transmissions or some mobile scenarios appear (so that the available bandwidth is changed), the framework can redistribute the current available bandwidth according to the service differentiation since it continuously keeps track of the current state of the network bandwidth and the current locations of the mobile nodes.
Besides the original fields in RREQ, the route request now also contains the bandwidth requirement of the new flow and the location of the source node.
Specifically, the amount of the required bandwidth is affected the location of the node, i.e., source, intermediate, and destination nodes require different local bandwidth for end-to-end bandwidth reservation.
Signal duration, bandwidth, and number of harmonics decreased, whereas the maximum, minimum and bandwidth of the fundamental, and peak spectral frequency all increased.
Evaluated by simulating wireless networks consisting of mobile hosts, the performance of the peer-tree based location lookup service exhibits high rates of successfully answering location queries, a low consumption on network bandwidth, and robustness to changes of network topology.
