Proportion based protocols for load balancing and lifetime maximization in wireless sensor networks

摘要: This paper presents the problem of minimizing energy consumption and maximizing lifetime in a many-to-one sensor network. In such network pattern, all nodes generate send data to single fixed base station (BS), via multi-hop transmissions. When have be forwarded BS routing, traffic pattern is highly non-uniform, putting high burden on close BS. Some strategies that balance ensure maximum by balancing load are proposed analyzed. The key element research use multiple transmission power levels. We studied an optimal solution for calculating hop-by-hop proportions particular case having just two levels, compared results given heuristics with those from analytical case. Another goal propose implement systematic approach construction based real nodes. neighbor discovery phase, way which finds out topology than impose strategy decide whether act locally or respect instruction sink part protocol described paper.
