Abstract: In order to solve the problem that the capability of wireless Ad Hoc networks will decrease with the increase of the number of nodes,the use of multi-radio multi-channel (MR-MC) to distribute resources and reduce the interfe-rence among nodes has become an important technical for the wireless network performance optimization.Therefore,we proposed a zero-one integer programming network optimization model and a tree-based channel assignment & link scheduling approach to make that the limited available channels can optimally work and ensure higher capacity increase in wireless Ad hoc networks.Then,we implemented the algorithms in Matlab7.0.The results show that our method performs much better than CCAS and the algorithm which only use channel assignment.

Key words: 0-1 integer programming,Network optimization,Resource allocation,Channel assignment,Link scheduling
