SimuLTE

SimuLTE is an open-source framework for simulating LTE and LTE-Advanced networks within the OMNeT++ discrete-event simulator. It provides a modular set of models that represent the radio access network, including eNodeBs, user equipment (UE), and the core protocols that operate over the radio interface.

Architecture and integration: It is implemented as a set of OMNeT++ modules and NED descriptions that can be used standalone or integrated with other OMNeT++ based frameworks such as INET for IP protocol stacks and Veins for vehicular networks. It supports mobility and scene configuration through standard OMNeT++ mechanisms and can be paired with external traffic generators to produce realistic data flows.

Radio and network modeling: SimuLTE models the LTE radio interface, including channel characteristics, interference, and link adaptation. It provides a choice of scheduling algorithms, and supports multiple antennas and diverse channel conditions, with options for handover and mobility-induced connectivity changes. The framework also includes a power consumption model to study energy use in base stations and devices.

Applications and usage: Researchers use SimuLTE to evaluate network performance under different LTE configurations, compare scheduling and handover strategies, study energy efficiency, and explore scenarios such as vehicular networks by coupling with Veins. The toolkit supports IP-based traffic, TCP/UDP, and can generate results suitable for academic publications.

Availability: SimuLTE is open-source and actively maintained by the academic and research community. Documentation and source code are available on its project repositories, and users contribute through updates and extensions.
