We propose using the predictability of human motion to eliminate the overhead of distributed location services in human-carried MANETs, dubbing the technique location profile routing. This method outperforms the Geographic Hashing Location Service when nodes change locations 2×more frequently than they initiate connections (e.g., start new TCP streams), as in applications like textand instant-m...

We introduce the concept of ”On Demand Connectivity Sharing”, which we build on top of User-Provided Networks (UPNs). UPNs were recently proposed as a new connectivity paradigm, according to which home-users share their broadband Internet connection with roaming guests. We enhance this paradigm with incentives, rules and policies, based on which: (i) home-users provide ondemand connectivity onl...

Remote homolog detection is one of the main issues in bioinformatics, and the profile-profile comparison is one of the most effective approaches. Recently, we have proposed a novel profile, match-node profile, constructed via profile HMM [6]. To evaluate the performance of match-node profile, we construct the profile by two popular HMM packages, HMMER [2] and SAM [4], and compared the performan...
