Software defined networks
Rahim Masoudi,Ali Ghaffari +1 more
TL;DR: Data plane, control plane and application plane as the three planes of SDN and the interfaces between them such as OpenFlow are investigated and the challenges and the latest technologies in relation to SDN are examined.
Journal ArticleDOI
Congestion control mechanisms in wireless sensor networks
TL;DR: A comprehensive survey of major congestion control mechanisms used in WSNs is presented and classifies the available methods into four categories i.e. traffic control protocols, resource Control protocols, queue assisted protocols and priority-aware protocols.
Journal ArticleDOI
An investigation of the impact of effective factors on the success of e-commerce in small- and medium-sized companies
Mahdi Choshin,Ali Ghaffari +1 more
TL;DR: Results based on the collected data from 180 staff employees of the Post Bank 1 in Eastern and Western Azerbaijan indicated that customer satisfaction, the amount of costs, infrastructures and knowledge and information are the effective's factors which have a significant impact on e-commerce success.
Journal ArticleDOI
Energy-Aware Clustering-Based Routing in Wireless Sensor Networks Using Cuckoo Optimization Algorithm
Melika Khabiri,Ali Ghaffari +1 more
TL;DR: An energy-aware clustering-based routing protocol was proposed in WSNs which is able to cluster the network and select optimal cluster heads and is better than other algorithms such as low energy adaptive clustering hierarchical (LEACH), application-specific low power routing, LACH-EP and LEACH with distance-based threshold.
Journal ArticleDOI
Energy-Efficient Routing Mechanism for Mobile Sink in Wireless Sensor Networks Using Particle Swarm Optimization Algorithm
Shamineh Tabibi,Ali Ghaffari +1 more
TL;DR: A new method called particle swarm optimization based selection (PSOBS) is proposed to select the optimal rendezvous points and the simulation results show the superiority of PSOBS as compared with WRPBS, but it increases the packet loss rate in comparison withWRPBS.
