Recently, the availability of numerous low-cost robotic units (e.g., Packbot, Robomote, and Khepera) has made it possible to massively deploy mobile sensors in a network and use them in a disposable manner. It has been shown that the controlled mobility offered by sensors can be exploited to improve the energy efficiency of a network. In this paper, we study a new problem called max-data mobile relay...
Clustering offers a kind of hierarchical organization to provide scalability and basic performance guarantee by partitioning the network into disjoint groups of nodes. In this paper an energy efficient clustering algorithm is proposed under large-scale mobile sensor networks scenario. In the initial cluster formation phase, our proposed scheme features a simple execution process, which has a time...
In autonomous ad hoc networks, nodes may act in their self-interest to improve their performance, perhaps at the expense of other nodes', or even the overall network's, performance. Besides, nodes are often mobile and must contend with limited and obsolete information about the operating state of network during their decision-making. We examine topology control of ad hoc networks and analyze the impact...
The problem of topology control is to assign per-node transmission power such that the resulting topology is energy efficient and satisfies certain global properties such as connectivity. The conventional approach to achieve these objectives is based on the fundamental assumption that nodes are socially responsible. We examine the following question: if nodes behave in a selfish manner, how does it...
