Sandeep Kour Ahuja, Abishek Gopalan, Srinivasan Ramasubramanian
2008 2008 5th International Conference on Broadband Communications, Networks and Systems  
In such networks, given a source and destination, it is of interest to compute a path and channel assignment on every link in the path such that the path bandwidth is the same as that of the link bandwidth  ...  Such a path must satisfy the constraint that no two consecutive links on the path are assigned the same channel, referred to as "channel discontinuity constraint."  ...  JOINT ROUTING AND CHANNEL ASSIGNMENT Problem Statement: Given a multi-channel wireless network with no collinear interference, the set of available channels on every link, the cost of the links, and a  ...
