  • A Cluster-Head Selection and Update Algorithm for Ad Hoc Networks
    2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010
    Co-Authors: Hao Wu, Zhangdui Zhong, Lajos Hanzo
    Abstract:

    A novel Cluster-Head selection and update algorithm "Type-based Cluster-forming Algorithm (TCA)" is proposed, which outperforms both the lowest node ID (LID) and the Weighted Clustering Algorithm (WCA) in the ad hoc network scenario considered. The system's performance is investigated in a scenario, when the 50 communicating nodes belong to three different groups, for example, a group of rescue workers, fire-fighters and paramedics. It is demonstrated that the carefully designed protocol is capable of outperforming the above-mentioned benchmarkers both in terms of a reduced number of Cluster-Head updates and Cluster-change events. Hence its quality-of-service may be deemed higher.

  • trust based Cluster Head selection algorithm for mobile ad hoc networks
    Trust Security And Privacy In Computing And Communications, 2011
    Co-Authors: Raihana Ferdous, Vallipuram Muthukkumarasamy, Elankayer Sithirasenan
    Abstract:

    Mobile Ad hoc Networks (MANETs) consist of a large number of relatively low-powered mobile nodes communicating in a network using radio signals. Clustering is one of the techniques used to manage data exchange amongst interacting nodes. Each group of nodes has one or more elected Cluster Head(s), where all Cluster Heads are interconnected for forming a communication backbone to transmit data. Moreover, Cluster Heads should be capable of sustaining communication with limited energy sources for longer period of time. Misbehaving nodes and Cluster Heads can drain energy rapidly and reduce the total life span of the network. In this context, selection of best Cluster Heads with trusted information becomes critical for the overall performance. In this paper, we propose Cluster Head(s) selection algorithm based on an efficient trust model. This algorithm aims to elect trustworthy stable Cluster Head(s) that can provide secure communication via cooperative nodes. Simulations were conducted to evaluate trusted Cluster Head(s) in terms of Clusters stability, longevity and throughput.

  • Assistant Cluster Head Clustering Algorithm Based on LEACH Protocol
    Computer Engineering, 2011
    Co-Authors: Li Fang
    Abstract:

    On the basis of LEACH,this paper proposes an assistant Cluster Head Clustering algorithm.In Wireless Sensor Network(WSN),according to the Cluster Head node's geographical location,remaining members of the Cluster energy and the number of nodes in the Cluster,the algorithm can dynamically determine whether to generate assistant Cluster Head and choose appropriate nodes in it,thus reducing the energy consumption of Cluster Head communication,while addressing some of the Cluster Head and base station communications.Simulation results show that this algorithm can effectively reduce the energy consumption,and extend the network lifetime.
