摘要: | Due to the great concerns of environmental protection and the high rising of prices in
oil, energy efficiency has become an important factor for designing network applications. In this
paper, we study an optimisation problem which is concerned about how to construct an Interferencefree
multicast tree subject to delay and energy constraints on a multi-channel multi-radio wireless
mesh network. Our objective is to maximise the number of mesh clients that can be included
in the multicast tree. This problem is referred as the EDMRM problem. To solve it, we first
propose an optimal algorithm on the basis of integer linear programming (ILP) for the EDMRM
problem. Since the ILP-based method is only feasible for small-scale networks, we also provide a
tabu-based heuristic algorithm for solving practical networks that consist of a large number of nodes.
The experimental results show that our tabu-based heuristic can outperform the other previously
proposed methods. |

摘要: | Given a sparse-splitting wavelength-division multiplexing network with no wavelength converter, we study a group multicast problem that is how to transmit a number of multicast streams from the video server to multiple destinations simultaneously. To avoid the situation that the wavelengths are used up by the first few requests, one wavelength is available for each multicast request. Hence, some of destinations may not be included in the multicast trees because of the lack of wavelengths. Our goal is to construct a number of light trees with conflict-free wavelengths for multiple requests so that the number of served clients is maximized. This problem is named as the revenue-maximized and delay-constrained group multicast routing problem. We first determine a set of multicast trees with the maximum number of served clients, then followed by the wavelength assignment to allocate the minimum number of wavelengths to the resulting trees. In this study, we propose two Integer Linear Programming ILP-based algorithms for determining the optimal solutions for the light-tree construction problem and the wavelength assignment problem, respectively. For large-scale networks, two heuristics are introduced to solve the light-tree construction problem approximately. A set of simulations are also provided for comparing performances of our algorithms against the other published methods. |

摘要: | Given a video/audio streaming system installed on a multichannel multiradio wireless mesh network, we are interested in a problem concerning about how to construct a delay-constrained multicast tree to support concurrent interference-free transmissions so that the number of serviced mesh clients is maximized. In this paper, we propose a heuristic approach called cross-layer and load-oriented (CLLO) algorithm for the problem. On the basis of the cross-layer design paradigm, our CLLO algorithm can consider application demands, multicast routing, and channel assignment jointly during the formation of a channel-allocated multicast tree. The experimental results show that the proposed CLLO outperforms the layered approaches in terms of the number of serviced mesh clients and throughputs. This superiority is due to information from higher layers can be used to guide routing selection and channel allocation at the same time. As a result, the CLLO algorithm can explore more solution spaces than the traditional layered approaches. In addition to that, we also propose a channel adjusting procedure to enhance the quality of channel-allocated multicast trees. According to our simulations, it is proved to be an effective method for improving the performance of the proposed CLLO algorithm. Copyright c 2013 John Wiley & Sons, Ltd.

摘要: | Given a video stream delivering system deployed on a multicast tree, which is embedded in a multi-channel multi-radio wireless mesh network, our problem is concerned about how to allocate interference-free channels to tree links and maximize the number of serviced mesh clients at the same time. In this paper, we propose a channel allocation heuristic algorithm based on best-first search and backtracking techniques. The experimental results show that our BFB based CA algorithm outperforms previous methods such as DFS and BFS based CA methods. This superiority is due to the backtracking technique used in BFB approach. It allows previous channel-allocated links to have feasibility to select the other eligible channels when no conflict-free channel can be found for the current link during the CA process. In addition to that, we also propose a tree refinement method to enhance the quality of channel-allocated trees by adding uncovered destinations at the cost of deletion of some covered destinations. Our aim of this refinement is to increase the number of serviced mesh clients. According to our simulation results, it is proved to be an effective method for improving multicast trees produced by BFB, BFS and DFS CA algorithms. |

摘要: | In this paper, we study a problem that is concerning how to construct a delay-constrained
multicast tree on a wireless mesh network (WMN) such that the number of serviced clients is
maximized. In order to support high-quality and concurrent interference-free transmission
streams, multiple radios are implemented in each mesh node in the WMNs. Instead of only
orthogonal channels used for the multicast in the previous works, both orthogonal and partially
overlapping channels are considered in this study. As a result, the number of links successfully
allocated channels can be expected to be much larger than that of the approaches in which only
orthogonal channels are considered. The number of serviced subscribers is then increased
dramatically. Hence, the goal of this study is to find interference-free and delay-constrained
multicast trees that can lead to the maximal number of serviced subscribers. This problem is
referred as the MRDCM problem. Two heuristics, load-based greedy algorithm and
load-based MCM algorithm, are developed for constructing multicast trees. Furthermore, two
load-based channel assignment procedures are provided to allocate interference-free channels
to the multicast trees. A set of experiments is designed to do performance, delay and efficiency
comparisons for the multicast trees generated by all the approximation algorithms proposed in
this study. |

摘要: | Traditionally, the optimization goal of multicast
routing in WDM optical networks is to minimize the number of
wavelengths and fibers used for the multicasting. In this paper,
we consider a problem concerned about how to multicast
several video streams simultaneously to a number of clients in a
given WDM network with sparse light spitting, where the
number of wavelengths on each link is given in advance. Our
goal is to construct a number of multicast trees for all required
streams so that the multiple constraints: bandwidth, delay and
multicast capability, are satisfied and the total number of clients
participating in all multicast sessions is also maximized. This
problem is referred as profit-oriented and delay-constrained
group multicast routing ( 𝐏𝐃𝐆𝐑𝐌 ) problem. Two heuristic
algorithms are proposed in this paper for this NP-hard problem.
A set of experimental results are also provided to compare the
performances of our heuristics with previous methods
published in literature. |
