Optimized Quality of Service for Real-Time Wireless Sensor Networks Using a Partitioning Multipath Routing Approach

Mohammed Zaki Hasan, Tat-Chee Wan
2013 Journal of Computer Networks and Communications  
We propose a novel mathematical model for quality of service (QoS) route determination that enables a sensor to determine the optimal path for minimising resource use while satisfying the required QoS  ...  The proposed mathematical model uses the Lagrangian relaxation mixed integer programming technique to define critical parameters and appropriate objective functions for controlling the adaptive QoS constrained  ...  Most of the previous existing routing metrics focused on only a single service metric such as energy, reliability, or energy in a single path.  ...

Performance evaluation of an intelligent CAC and routing framework for multimedia applications in broadband networks

Makoto Ikeda, Leonard Barolli, Akio Koyama, Arjan Durresi, Giuseppe De Marco, Jiro Iwashige
2006 Journal of computer and system sciences (Print)  
The simulation results show that proposed framework has a good performance and is a promising method for QoS routing and CAC decision.  ...  In this work, we extend our previous work by proposing and implementing new algorithms based on Fuzzy Logic (FL) and Genetic Algorithm (GA) which use for CAC and routing many QoS parameters.  ...  The ARGAQ uses a single mixed metrics (T), which is the ratio of DT and TSR.  ...

Distance-Vector QoS-Based Routing with Three Metrics [chapter]

Luís Henrique M. K. Costa, Serge Fdida, Otto Carlos M. B. Duarte
2000 Lecture Notes in Computer Science  
Classes of service and metriccombination are used to turn the algorithm scalable and as complex as a two-metric one.  ...  A more suitable solution is to use per-flow state only for special flows (flows that have stringent QoS requirements which demand a value-added service).  ...  Single Mixed Metric Since algorithms based on a single metric are well known, a direct approach is to map the user's QoS requirements into a single measure and use it as metric.  ...

Indeed, the problem of QoS Routing with multiple additive constraints is known to be NP-hard.  ...  The provisioning of QoS based network services is in general terms an extremely complex problem, and a significant part of this complexity lies in the routing layer.  ...  By combining a set of QoS metrics in a single metric, it is possible to use existing polynomial-time path computation algorithms, such as Bellman-Ford or Dijkstra.  ...

Multiobjective Optimal Secure Routing Algorithm using NSGA-II

Dan. Han, Hu Guang-min, Cai Lu
2008 2008 IEEE Conference on Cybernetics and Intelligent Systems  
Integrating security metric into QoS framework is a new strategy in secure routing. Existing QoS framework use only one security metric to describe the link security.  ...  Aiming at the deficiency of existing secure routing, we propose a novel strategy which employs multi-security metrics as QoS parameters to achieve more secure route.  ...  For the unilateral problem that integrating only one kind of security metric into QoS framework, we propose a novel multi-security metric strategy for QoS-based routing.  ...

Joint multi-cost routing and power control in wireless ad hoc networks

Nikos Karagiorgas, Panagiotis Kokkinos, Christos Papageorgiou, Emmanouel Varvarigos
2010 Wireless networks  
The multi-cost routing problem is a generalization of the multi-constrained problem, where no constraints exist, and is also significantly more powerful than single-cost routing.  ...  In multi-cost routing, a vector of cost parameters is assigned to each network link, from which the cost vectors of candidate paths are calculated.  ...  In [9] a new cost metric is used for routing, which is a function of the remaining battery level and the number of neighbours of a node.  ...

QoS Routing in Diffserv MPLS Networks

K.K. Phang, T.C. Ling, T.F. Ang
2009 Malaysian Journal of Computer Science  
A polynomial time, heuristic dynamic routing algorithm, namely TE-QOSPF-Mix, is proposed to provide a better trade-off between hop-count and bandwidth optimization.  ...  With the emergence of new network applications and quality of service (QoS) requirements, current Internet technology that supports best-effort service is clearly insufficient.  ...  TE-QOSPF-Mix uses two metrics, that is, hop-count and available bandwidth. Future work on TE-QOSPF-Mix may consider the incorporation of additional constraints within the path finding metrics.  ...
