Optimal Clustering Architecture to Maximize Sensor Network Lifetime
نویسندگان
چکیده
Wireless Sensor Networks have been widely used in many domains, such as scientific explorations, industrial applications etc. Sensor nodes are dedicated to perform functionalities such as relaying, sensing and aggregation, which quickly drain energy of the node. Due to relay traffic, nodes closest to sink tends to deplete energy faster than others due to heavier relay traffic. Thus UnEven energy depletion phenomenon is defined as energy hole problem. Clustering enhances network lifetime but achieving even energy depletion is challenging. Energy-aware head rotation is used to balance energy depletion and more clusters are constructed with each cluster being smaller, towards the sink.

LEACH is the most popular clastering algorithm in Wireless Sensor Networks (WSNs). However, it has two main drawbacks, including random selection of cluster heads, and direct communication of cluster heads with the sink. This paper aims to introduce a new centralized cluster-based routing protocol named LEACH-AEC (LEACH with Adaptive Energy Consumption), which guarantees to generate balanced cl...

One of the main challenges in Wireless Sensor Networks is the limited energy of nodes which can cause to reduce the lifetime of nodes and whole network respectively. Transmissions between the nodes consumes most of the nodes' energy so minimization of unnecessary transmissions can led to reduction of energy consumption. Therefor routing protocols designed based on optimal energy consumption are...

متن کاملCOCA: Constructing optimal clustering architecture to maximize sensor network lifetime
In wireless sensor networks, clustering is an effective technique to extend the network lifetime. However, in the multi-hop clustering model, if the nodes are uniformly distributed and the clusters are of equal size, the cluster heads closer to the sink have to relay much heavier traffic, leading to the ‘‘energy hole’’ problem. Unequal clustering structures have been proposed to mitigate the ‘‘...
