    Abstract: Wireless sensor nodes are battery-powered devices with limited processing and transmission power, energy-efficient configuration has become a major design goal to improve the lifetime of the network. A cluster-based network topology can increase the scalability and lifetime, the classical clustering solutions elect the cluster head according the nodes’ residential energy in homogeneous networks, and however, the network is mostly inhomogeneous in practical application. In this paper, a cluster head election mechanism is proposed in a network which deploys the nodes with non-uniform energy and data gathering rates. This protocol is able to distribute energy consumption more reasonable among the sensors in the network, and make each node lifetime more similar.

    A Hybrid Transmitting Algorithm for Unequal Cluster-Based Routing Wireless Sensor Networks
    Trans Tech Publications, Ltd. ; 2014

    Abstract: A cluster-based network topology enables the efficient utilization of the limited energy resources in network; based on multi-hop clustering model, the unequal routing protocol can lead to uniform energy dissipation among the cluster head and achieves some improvement on the network lifetime. However, the bottleneck zone, where the energy of the nodes closer to the Sink is depleted quickly, still limits the network lifetime in some cases; especially the collecting data cant be compressed. In this paper, a Hybrid transmitting protocol for Unequal Cluster-based Routing WSN(H-UCR) was proposed, which combined single-hop and multi-hop transmission is implemented to balance the energy dissipation among the entire network. Simulation results demonstrate that our proposed approach is effective in balancing the energy consumption and prolonging the network lifetime.

    Abstract: Wireless Sensor Networks (WSNs) allows users to accurately monitor a environment by intelligently combining the data from the distributed nodes. A cluster-based network topology can increase the scalability and lifetime, the cluster head gathering the data and transmitting them to Sink with single hop or multi-hop communication. In this paper, the energy consumption model for clustering networks were analyzed and an adaptive energy-efficient routing approach was given, then the hop mode selection condition was analyzed and simulated.

    An Unequal Fan-Shaped Cluster Routing Protocol for Wireless Sensor Networks

    Abstract: A cluster-based network topology can increase the scalability and lifetime. However, the area around the Sink node forms a bottleneck zone due to heavy traffic-flow, which limits the network lifetime in WSN, the energy of the nodes closer to the sink node is depleted very quickly and the network die early, so it is important to ensure that the network energy dissipation is balanced. In this paper, an unequal fan-shaped clustering (UFC) model was proposed, which can lead to more uniform energy dissipation among the entire network, thus increasing network lifetime. The results show that UFC can lead to more uniform energy dissipation in a homogeneous network and prolong network lifetime.
