Abstract:
1. A method for discovering a path between a source node and a destination node in mesh wireless media (WiMedia) based networks, wherein the path has sufficient medium time to enable efficient data transfers over the path, the method comprising: upon receiving a route request (RREQ), computing a number of available medium access slots (MAS) of a wireless link between a node receiving the RREQ and a node transmitting the RREQ; computing a number of required MAS to deliver data over the wireless link in an upstream direction, wherein the computation of the number of required MAS is based on a bandwidth requirement and effective channel rates of the path; updating a local neighbor link (LNL) list when the number of required MAS is not above the number of available MAS; computing an upper bound value and a lower bound value of a sufficient medium time coefficient (C NMASr(i) is the number of required MAS for a wireless link (i) and NMASa(i) is the number of available MAS for a wireless link (i) out of ‘m’ links; and selecting the path based on at least the upper and lower bound C
