           Appeal No. 2006-2754                                                                      
           Application No. 10/108,109                                                                
           1363, 63 USPQ2d 2002, 2008 (Fed. Cir. 2002).                                              
                 An obviousness analysis commences with a review and                                 
           consideration of all the pertinent evidence and arguments.  “In                           
           reviewing the [E]xaminer’s decision on appeal, the Board must                             
           necessarily weigh all of the evidence and argument.”  Oetiker,                            
           977 F.2d at 1445, 24 USPQ2d at 1444.  “[T]he Board must not only                          
           assure that the requisite findings are made, based on evidence of                         
           record, but must also explain the reasoning by which the findings                         
           are deemed to support the agency’s conclusion.”  In re Lee, 277                           
           F.3d 1338, 1344, 61 USPQ2d 1430, 1434 (Fed. Cir. 2002).                                   
                 With respect to claims 1 through 7, 9, 10 and 12 through 15,                        
           Appellants argue in the Appeal and Reply Briefs that Ramanathan                           
           does not teach the claimed invention.  Particularly, Appellants                           
           assert that Ramanathan does not teach the limitation of a node                            
           self-initiating a self-assessment of its ability level to serve                           
           as a cluster head based on a formula that assigns weights to at                           
           least two characteristics of the node.  We have already addressed                         
           this argument in the discussion of claim 8 above, and we agree                            
           with Appellants.  Further, Appellants argue that none of the                              
           secondary and tertiary references, Bak and Passman, cures the                             
           deficiencies of Flannery.  We agree with Appellants.  Our review                          
           of these references reveals that they do not cure Ramanathan’s                            

                                                 14
