Item EAMP-AIDC - energy-aware mac protocol with adaptive individual duty cycle for EH-WSN(Institute of Electrical and Electronics Engineers Inc., 2017) Bouachir, Ons; Mnaouer, Adel Ben; Touati, Farid; Crescini, DamianoNetwork lifetime is the main issue of wireless sensor networks and IoT solutions in real world application. Sensors cannot have an infinite lifetime without battery recharge or replacement. Energy harvesting, from environmental energy sources, is a promising technology to provide sustainable powering for WSN. However, based on harvesting opportunities, nodes power may alternate between two states: a state with sufficient residual power and another with shortage in power. Hence, it is paramount to develop robust networking platforms that are energy-harvesting-aware and that support low-energy consumption and data integrity in a noisy, variable environment. In this paper, we present the EAMP-AIDC protocol, an energy aware MAC protocol for EH-WSN based on individual duty cycle optimization. It takes into consideration nodes' residual energy and application and data requirements in order to define individual dynamic duty cycles (Active and sleep periods) that allow to create a balanced load in term of cooperative data relaying tasks and in terms of energy consumption between the different participating nodes so as to ensure continuous network operation. The proposed protocol was evaluated using the network simulator OMNET++ and was compared to the standard IEEE 802.15.4 MAC. The results showed that EAMP-AIDC protocol outperformed the IEEE 802.15.4 standard in term of better energy consumption, increased survivability in energy savings and in guaranteeing continuous operations. © 2017 IEEE.Item Opportunistic routing and data dissemination protocol for energy harvesting wireless sensor networks(Institute of Electrical and Electronics Engineers Inc., 2016) Bouachir, Ons; Mnaouer, Adel Ben; Touati, Farid; Crescini, DamianoRecent advances in environmental sources harvesting technologies is a promising solution to provide sustainable energy sources for wireless sensor networks (WSN). Renewable energy sources such as solar, thermal and electromagnetic waves constitute viable alternatives to maximize the network lifetime. Therefore, networking software awareness and adaptability to energy availability conditions should translate into innovative supporting features for data gathering, aggregation, routing and dissemination. Thus, it is paramount to develop robust energy harvesting-aware networking platforms that support the above services and guarantee low energy consumption and data integrity in a noisy, constrained environment. In this paper, we present an opportunistic routing and data dissemination protocol for energy harvesting wireless sensor network (EH-WSN) based on cross-layer constructs that allows across the layers synchronization and coordination between the routing protocol and the application layer services. The OMNET++ based extensive simulation of this protocol showed promising results in terms of meeting application requirements of handling urgent traffic and delay tolerant traffic seamlessly and ensuring energy usage efficiency. © 2016 IEEE.Item PEAM : a polymorphic, energy-aware MAC protocol for WBAN(Institute of Electrical and Electronics Engineers Inc., 2016) Bouachir, Ons; Mnaouer, Adel Ben; Touati, FaridIn remote healthcare monitoring and care delivery, obtaining the right information at the right time is critical. For these systems, designing an efficient MAC protocol that is able to meet the challenges on network quality such as throughput, latency, data reliability and energy saving is an imperative task. This paper presents a polymorphic, multi-behavioral MAC protocol called PEAM (Polymorphic, Energy-Aware MAC Protocol) designed to support WBANs used in ubiquitous healthcare monitoring systems. The adaptability feature characterizing the protocol is essential in handling different patients' health states. PEAM was designed based on cross-layer constructs that allow across the layers synchronization and coordination orchestrated by the application layer and targeting the Data link layer services. PEAM has also been enabled to interplay with IPv6 networks through interaction with the 6LowPAN middleware. This protocol was evaluated and compared to the well-known IEEE 802.15.4 standard using the network simulator OMNET++, and exhibited clear superiority. © 2016 IEEE.Item Review - Challenges of mobility aware MAC protocols in WSN(Institute of Electrical and Electronics Engineers Inc., 2018) Sudheendran, Sijo; Bouachir, Ons; Moussa, Sherif; Dahmane, Adel OmarIn today's smart world WSN plays an important role in IoT. The WSN nodes can be used for wildlife, patient, air quality monitoring. WSN consists of numerous sensor nodes that are connected to each other. One of the major concerns of WSN is the mobility of nodes. The mobility of the nodes creates concern to the MAC protocols that's defined for WSN static nodes. Mobile-WSN demands the participated nodes to send packets with a bursty traffic, low energy consumption and reliable connection. MAC protocol is the most important in designing the WSN as MAC plays an important role regarding throughput, mobility, security and energy consumption. This paper gives a review on mobility aware protocols such as M-MAC, MA-MAC, MMH-MAC, M-Contiki, MobiIQ, MobiDisc. © 2018 IEEE.
