Abstract:
In the context of Wireless Sensor Networks (WSNs), where sensors have limited energy power, it is necessary to carefully manage this scarce resource by saving communications. Clustering is considered as an effective scheme in increasing the scalability and lifetime of wireless sensor networks. We propose an energy-aware distributed self-stabilizing clustering protocol based on message-passing for heterogeneous wireless sensor networks. This protocol optimizes energy consumption and prolongs the network lifetime by minimizing the number of messages involved in the construction of clusters and by minimizing stabilization time. Our generic clustering protocol can be easily used for constructing clusters according to multiple criteria in the election of cluster-heads, such as nodes' identity, residual energy or degree. We propose to validate our approach under the different election metrics by evaluating its communication cost in terms of messages, stabilization time, energy consumption and number of clusters. Simulation results show that in terms of number of messages and energy consumption, it is better to use the Highest-ID metric for electing CHs. However, the criterion of energy provides a better distribution of clusters.
