A Reliability-Oriented Local-Area Model for Large-Scale Wireless Sensor Networks

摘要: Large-scale wireless sensor networks (WSNs) have demonstrated some complex features which are similar to those of other types networks, such as social networks. Based on these features, evolution process and characteristic WSNs, we represent a WSN topologically by building suitable model, is named the reliability-oriented local-area model (ROLM) aimed at improving performance WSNs. For analyzing ROLM, define reliability probability that relative error between measurement true value equal or less than proposed parameter measure network. them, use analyze influence network structure reliability, compared reliabilities ROLM existing Experiment results prove large-scale follows power-law distribution, it has scale-free small world characteristic. And also shows that, comparing with not only balances energy consumption limiting connectivity each node prolong lifetime network, but improves substantially. can be used express topology WSNs preferably.
