Creating a hierarchical structure by clustering has been considered an effective method to improve the performance of ad hoc networks, such as scalability and stability. This is particularly important for networks with mobile nodes, where the mobility can cause randomly and dynamically changed network topology. In this paper, we propose a mobility prediction-based clustering (MPBC) scheme for ad hoc...
This paper proposes an Energy Efficient Clustering Scheme for mobile ad hoc networks. In the initial clustering stage, a node's residual energy, nearby topology, relative location and relative mobility are used for determining whether the node is suitable for being a cluster head. In the cluster maintaining stage, a strategy called Distance Estimation Broadcasting is designed to help a cluster member...
This paper addresses the clustering problem for highly mobile ad hoc networks. In the proposed scheme, Doppler shifts associated with received signal are used to estimate the relative speed between cluster head and cluster members. With the estimated speed, a node can predict its stay time in every nearby cluster. In the initial clustering stage, a node joins a cluster that can provide it with the...
