Energy consumption is a key concern in the deployment and operation of current data networks, for which software-defined networks (SDNs) have become a promising alternative. Although several works have been proposed to improve the energy efficiency, these techniques may lead to performance degradations when QoS requirements are neglected. Inspired by this problem, this letter introduces a new routing...
Since the heterogeneous Internet Service Provider (ISP) router policies prevent the quality-of-service (QoS) multimedia applications which require IP layer multicasting from being widely deployed on the Internet, the mechanism of implementing such applications by application layer broadcasting through organizing the multicast group in a peer-to-peer overlay network is proposed. In this paper, we study...
In this paper, we propose to design a backup route establishment for QoS routing protocol. In this protocol, the potential failures of network and node are identified and a backup routing is initiated. For detection of failures, a path evaluation function is determined based on the metrics energy drain rate and interference, congestion status are measured. The primary path satisfying the QoS parameters...
Network path identification is an important problem in networks. It is important to identify routing path for data transfer from a source to destination. Network path found should be feasible in overcoming congestion, real time data transfer. This paper reviews three different methods to find network path identification using biologically inspired algorithms in different scenarios. It will provide...
Quality of Service (QoS) routing is one of the key enabling techniques for multimedia wireless sensor networks (WSNs). However, the multi-constraints QoS routing problem is an NP-hard problem, and the computational complexity of an exhaustive search over all the paths is too high for large scale multimedia WSNs. In this paper, a novel parallel elite clonal quantum evolutionary algorithm is proposed...
Vehicular ad hoc networks (VANETs) are infrastructure-less and self-organized networks deployed among vehicles and other road users. Due to the limitations of the wireless technologies used and the rapid topology changes, designing efficient routing protocols for VANETs is becoming a major concern. In this study, we applied a multi-objective optimization metaheuristic, in order to find efficient OLSR...
