Robotic sensor network (RSN) contains mobile sensors and robots provides feasible solution for many multiagent applications. One of the most critical issues in RSN and its application is how to effectively assign tasks. This paper presents a novel threshold-based task allocation strategy to answer the question particularly for RSN. Firstly, we model the task allocation in RSN to distinguish the discovering...
In dynamic network, including both the mobile ad-hoc network as well as the wireless sensor network, the services need to be provided putting into consideration the challenges of resource mobility and availability. Devices with a short switched-on period together with mobility and ad-hoc connections make the network connection highly unreliable. Mobility change not only brings with it a corresponding...
This paper studies the incentive mechanism for selfish nodes in Ad Hoc network. We propose a service negotiation mechanism based on WASP algorithm and genetic algorithm (GA). The mechanism has been improved in two areas, first it presents a filtering strategy to select the negotiation nodes, and in addition, it adopts an improved genetic algorithm to generate the offers. In filtering strategy, the...
Since there is no central management center in the MANETs, nodes need to self-manage service provided by other nodes. To pursue maximal utilities, they should be able to negotiate autonomously for services, e.g., packets transmission, information share. While some selfish mobile nodes in MANETs are unwilling to provide services for other users, it directly leads to serious decline in network performances...
Restoring connectivity subjected to the failure of mobile node(s) is an important research challenge in mobile ad hoc networks. To achieve this objective, a Connectivity Restoration Strategy (CRS) is developed, aiming at restoring the connectivity of mobile network whenever it is partitioned from multiple simultaneous node failures. The proposed strategy is fully distributed and requires only local...
Topology control serves as an important technique in dynamic networks for its capabilities of reducing energy consumption and radio interference. Additionally, the sparse network structure generated by topology control algorithms is beneficial for enhancing network coverage. In this paper, a local two-tier topology control method is developed to address the issues of topology control and coverage...
In a clustering-based MANETs, task allocation has posed increasing research challenges because the needs of management and coordination are accentuated by complicated demands of cluster members. A self-adaptive method of task allocation is designed to facilitate self-planning and self-negotiation for nodes during tasks being distributed and executed. The method is composed of two parts: for one part,...
Self-configuration management of mobile ad-hoc networks (MANETs) depends upon the hierarchical architecture and topology change of the network. By analyzing role shift and behavior changes of nodes in the clustering-based MANETs, a self-configuration management model is proposed in this paper. In view of unpredictability of the node behavior, a cluster unit provides the auto-configuration mechanisms...
