    Revisiting Directed Diffusion In The Era Of IoT-WSNs : Power Control For Adaptation to High Density
    (IEEE Xplore, 2017-08-28) Khelladi, Lyes
    Wireless Sensor Networks (WSNs) have been recognized as a crucial and enabling technology in the world of Internet of Things (IoT). However, their integration with IoT arises new design challenges, compared to conventional WSNs applications. This paper addresses the challenge of high node density and its impact on the design of IoT-WSNs routing protocols. We propose a power-aware topology control mechanism built upon the prominent routing scheme, Directed Diffusion. Moreover, we take benefit from the power-awareness feature of the topology control mechanism in order to compute an energy consumption metric, allowing the selection of energy-efficient routes. The simulation results demonstrate an improvement by the proposed protocol in terms of energy efficiency, data reporting delays and delivery success rate.

    Scalability of Wireless MAC Protocols in Mobile Ad hoc Networks
    (IEEE, 2005-07) Djenouri, Djamel; Bouznada, Mohamed; Khiyat, Faten; Khelladi, Lyes
    The rapid proliferation of lightweight wireless mobile devices, such as laptops, PDAs, and sensors makes mobile ad hoc networks (MANETs) an exciting and important research area nowadays. The MANET community have been concentrating on some problems related to the network layer, especially on the routing protocols. But regarding the MAC layer, little has been done. Our contri- bution in this paper is the deep investigation of the MAC protocols scalability in MANETs, using the GloMoSim simulation tool. We think we are the first who consider the scalability factor when analyzing MAC protocols in MANETs.
