A Clustering Routing based on Dijkstra Algorithm for WSNs
Abderrahim M.; Hakim H.; Boujemaa H.; Touati F. ( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)Wireless Sensor Networks (WSNs) have witnessed a growing interest in the last two decades owing to its various advantages. Thus, in a big WSN, using one hop transmission, as in LEACH algorithm, causes loss of a lot of ... -
Energy-Efficient Transmission Technique based on Dijkstra Algorithm for decreasing energy consumption in WSNs
Abderrahim M.; Hakim H.; Boujemaa H.; Touati F. ( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)In this paper, we propose an energy-efficient multihop transmission technique for Wireless Sensor Networks (WSN) based on Dijkstra algorithm. We consider a WSN composed of N sensor nodes. Firstly, we group the sensor nodes ... -
Multihop transmission strategy using dijkstra algorithm to improve energy efficiency in WSNs
Abderrahim M.; Hakim H.; Boujemaa H.; Touati F. ( Springer Verlag , 2018 , Conference Paper)Thanks to the development in the wireless communication technologies and the microelectronics domain, Wireless Sensor Networks (WSNs) are more and more omnipresent. The most important challenge of WSN is how to extend its ... -
Secrecy Performance Analysis of Cooperative NOMA system with multiple DF Relays
Zaghdoud N.; Mnaouer A.B.; Boujemaa H.; Touati F.

Secrecy Performance Analysis of Multi-Antenna NOMA System with AF/DF relaying under External and Internal Eavesdropping Scenarios
Zaghdoud N.; Mnaouer A.B.; Alouane W.H.; Boujemaa H.; Touati F. ( Institute of Electrical and Electronics Engineers Inc. , 2020 , Conference Paper)Due to the successive interference cancellation (SIC) technique, Non orthogonal multiple Access (NOMA) users have the capability of decoding the other paired users sharing the same resource bloc. As a result, NOMA technique ... -
Secrecy performance of AF relaying in cooperative NOMA over rician channel
Zaghdoud N.; Alouane W.H.; Boujemaa H.; Mnaouer A.B.; Touati F. ( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)In this paper, we investigate the secrecy performance of an Amplify-and-Forward (AF) relay in a cooperative NOMA system. The AF relay ensures the transmission of the signal in the presence of one passive eavesdropper where ... -
