Researchers at Chiba University introduced 'Dual Perigee,' a decentralized algorithm that helps IoT devices prefer faster network peers, featuring passive latency measurements that trim slow connections. The team, led by Associate Professor Kien Nguyen and published in IEEE Transactions on Network and Service Management, designed the method for lightweight deployment on constrained devices.
Dual Perigee evaluates incoming transaction and block delivery speeds, dropping consistently slow neighbors and reconnecting to better-performing nodes so the network self-optimizes. In simulations of a 50-node IoT blockchain, the approach reduced block delays by about 48.5% versus Ethereum’s standard propagation and outperformed prior Perigee variants; the algorithm uses existing traffic data and minimal processing, avoiding extra device load.
For consumers and operators, faster confirmation and lower latency mean blockchain can support real-time IoT use cases like smart cities and industrial monitoring. By reorganizing peer links without central control, Dual Perigee makes secure, decentralized IoT systems more practical and responsive.
