This paper proposes a variant of the low energy adaptive clustering hierarchy (LEACH) routing protocol that is suitable for energy harvesting wireless sensor networks (EH-WSNs). In the proposed design, the cluster head (CH) role is shared by the network nodes so that the associated energy consumption is balanced between the nodes with duty cycling as a function of the nodes' energy harvesting capabilities...
Cognitive radio (CR) is an intelligent radio that can coexist with licensed users without affecting their QOS. It is very likely that 5G devices will have CR functionalities. To simulate CR models Cognitive radio network (CRN) simulators are used. In this paper we have investigated various open source CRN simulators. We have chosen two open source CRN simulators i.e. crSimulator and CRE-NS3. To study,...
Most network simulators do not support security features. In this paper, we introduce a new security module for OMNET++ that implements the IEEE 802.15.4 security suite. This module, developed using the C++ language, can simulate all devices and sensors that implement the IEEE 802.15.4 standard. The OMNET++ security module is also evaluated in terms of quality of services in the presence of physical...
