CALL ADMISSION CONTROL IN AN AD HOC NETWORK

A wireless node (n5) can control its admission as an incoming node to a network in which communication takes place between nodes (n1, n2, n3 etc) over wireless links (m). The incoming node (n5) monitors transmissions of transmitter nodes in the network to provide location data corresponding to their...

description A wireless node (n5) can control its admission as an incoming node to a network in which communication takes place between nodes (n1, n2, n3 etc) over wireless links (m). The incoming node (n5) monitors transmissions of transmitter nodes in the network to provide location data corresponding to their respective locations. The node (n5) has a controller (7) that develops simulated location data corresponding to the locations of receiver nodes in the network using the location data for the transmitter nodes. The controller constructs a link gain matrix using the location data for the transmitter nodes and the simulated location data for the receiver nodes, and processes the matrix to compute the maximum achievable value of the signal to interference relationship (SIR) for the network when the incoming is assumed to have joined the network, and the incoming node is admitted to the network if the maximum value exceeds a threshold. The accuracy of the simulated receiver location data is tested by analysis of the link gain matrix without including the incoming node.
