LEACH (Low Energy Adaptive Clustering Hierarchy) is a clustering-based protocol that utilizes randomized rotation of the cluster-heads to evenly distribute the energy load among the sensor nodes in the network. This classical protocol has been widely used in wireless sensor network (WSN). However, it has the disadvantage of irrationality of electing cluster-head and of unbalanced energy consumption...
Monitoring grain storage situation is playing a very important role in grain storage safety. Traditional monitor system for grain depots has several drawbacks, such as large cable coverage, more interference and lighting strike, high maintenance cost and so on. To deal with these issues, a novel scheme of the monitor system for grain depots is proposed based on wireless sensor network (WSN). This...
The network routing could be simplified by clustering algorithm in wireless sensor network (WSN). Aimed at the occasion with a large amount of nodes but without whole-network time synchronization mechanism, a self-adaptive clustering algorithm for network topology control is proposed. In this algorithm, the cluster structure can be adjusted automatically according to the nodes distribution and network...
