Indian Institute of Science (IISc), Bangalore, India Selection Criteria and Distributed Selection Algorithms in Wireless Cellular and Sensor Networks Neelesh B. Mehta ECE Department, IISc New Project Proposal

Indian Institute of Science, Bangalore Outline Research problem and applications Proposed approach –Author ’ s previous work in this area Project milestones Budget estimates

Indian Institute of Science, Bangalore Research Problem Background Selection arises naturally in several wireless systems –Cooperative communications –Cellular communications Two key questions in selection –Whom to select? Selection criterion depends on system –How to select? Timer algorithm Fast, scalable, and distributed s r1r1 t r2r2 r3r3 h1h1 h2h2 h3h3 h4h4

Indian Institute of Science, Bangalore Proposed Approach Selection algorithm: Find optimal mapping –Maximize overall throughput for rate-adaptive systems –Minimize average BER for non- adaptive systems Selection metric –Determine how important it is to account for channel and battery states –Evaluate ‘dumb’ criteria –Propose new smart criteria Metric Timer Optimal mapping will look like
