                                      In the area of 
                                      algorithms for efficient Web design and 
                                      performance evaluation, we studied the 
                                      optimal hotlink assignment problem. We 
                                      proposed new algorithms which are capable 
                                      of obtaining considerable savings on the 
                                      access cost of the web site. We also built 
                                      the hotlink optimizer (HotOpt), a new 
                                      software tool that helps administrators 
                                      and designers to structure their web sites 
                                      efficiently. In rendezvous and exploration 
                                      problems in peer-to-peer computing, we 
                                      developed several new efficient algorithms 
                                      to enable a mobile agent to explore a 
                                      network with low memory. We also developed 
                                      a new set of algorithms (both randomized 
                                      and deterministic) for the mobile agent 
                                      rendezvous problem with tokens. The first 
                                      step in forming an ad-hoc network is the 
                                      discovery of other nodes. This procedure, 
                                      called node discovery, involves two or 
                                      more nodes in an ad-hoc, multichannel 
                                      broadcast system that want to establish a 
                                      common communication channel. Our 
                                      contribution in this area concerns new 
                                      algorithms for access control in Bluetooth 
                                      networks. In the area of connectivity in 
                                      wireless and sensor networks, and 
                                      computing with location awareness we 
                                      studied how evolving wireless networks (adhoc, 
                                      sensor) take advantage of location 
                                      awareness of the hosts and do not need any 
                                      infrastructure to maintain efficiently 
                                      connectivity, routing information and 
                                      other communication primitives.
