Clustering is a method for hierarchical management of a network. Especially, clustering is often used in MANETs. Johnen et al. proposed a self-stabilizing clustering algorithm which treats a MANET as a vertex-weighted graph. The algorithm has autonomous adaptability against topology changes and weight changes, while it does not consider the stability of clusters. In this paper, we present a weight...
Mobile ad-hoc networks (MANET) are particularly vulnerable on account of its intrinsic characteristics of open medium, dynamic topology, absence of central authorities, distributed cooperation and constrained capability. These vulnerabilities create significant challenges for routing protocols operating in the entire network. In which, the reactive routing, i.e. AODV, bears the brunt of various kinds...
Emergency services and networks are an emerging area of scientific research. During an emergency scenario such as forest fires, earthquakes, tsunamis and terrorist attacks rescuers need to establish communication to coordinate their actions by using smart and lightweight mobile devices. To this end, autonomous networks should be utilised to support the afore communications. Mobile Ad-hoc Networks...
A mobile ad hoc network can be defined as a network that is spontaneously deployed and is independent of any static network. The network consists of mobile nodes with wireless interfaces and has an arbitrary dynamic topology. The networks suffers from frequent link formation and disruption due to the mobility of the nodes. A clustering method is used for obtaining a hierarchical organization for the...
This paper proposes a dynamic energy efficient clustering algorithm for mobile ad hoc networks (MANETs). The proposed algorithm elects first the nodes that have a higher energy and less mobility as cluster-heads, then periodically monitors the cluster-heads' energy and locally alters the network topology or the clusters to increase the network lifetime by reducing the energy consumption of the suffering...
