In this paper, we introduce the stable path topology control problem for link-state routing in mobile multi-hop networks. We formulate the topology control problem of selective link-state broadcast as a graph pruning problem with restricted local neighborhood information. We develop a multi-agent optimization framework where the decision policies of each agent are restricted to local policies on incident...
This paper proposes a topology control method based on formation maintenance and nodes in different groups, which mainly involves issues on the network topology variation caused by the inconsistent velocities of all nodes and communication failure between local nodes and different groups in mobile robot team. It embodies the important role of formation maintenance associated with making groups when...
We describe and verify convergence properties of our forced-based genetic algorithm (FGA) as a decentralized topology control mechanism distributed among software agents. FGA uses local information to guide autonomous mobile nodes over an unknown geographical terrain to obtain a uniform node distribution. Analyzing the convergence characteristics of FGA is difficult due to the stochastic nature of...
Topology control aims to provide more spatial reuse and power conservation while keeping network's connectivity. However just a few number of efforts focused on the issue of topology control with mobility. Some of topology control algorithms (e.g. CEC) try to provide more energy conservation by sleeping the redundant nodes. This paper presents a sleep-based topology control algorithm, which is in...
There is great interest in using mobile adhoc networks (MANETs) for military and civilian applications. There are still a lot of interesting problems investigating the capacity and the optimal design of these networks. This paper looks at one of these outstanding problems. Specifically the problem addressed is to determine how the capacity of a MANET can be increased by the optimal placement of an...
This paper presents two novel mechanisms for the OLSR routing protocol, aiming to improve its energy performance in Mobile ah-hoc Networks. Routing protocols over MANET are an important issue and many proposals have been addressed to efficiently manage topology information, to offer network scalability and to prolong network lifetime. However, few papers consider a proactive protocol (like OLSR) to...
