Thesisuplink channel access and power management for M2M communications in LTE
The Mobile Communications department of Eurecom invites applications for a PhD position in the area of collaborative multicasting and resource management in the LTE-Advanced and rapidly-deployable mesh Networks. The position focuses mainly on scheduling algorithms for cellular (LTE / LTE-A) and Mesh networks by taking into account the applications QoS requirements and traffic type for the optimization of unicast and multicast transmission in terms of throughput, error rate, and latency. Issues related to coordinated scheduling between the relay nodes and base station (eNB) will also be addressed. Pour la transmission multicast, due to diverse channel conditions across receivers of members of the multicast group, the primal challenge is to manage resources (relaying nodes, transmission powers, channels) such that optimal and uniform multicast throughput is achieved across all receivers. We will explore the idea of dynamically partitioning the multicast group into two subsets, each subset with a different average channel quality. Then, some node in the subset with good channel quality can be used as relay for delivering the multicast information to nodes at the other subset of lower channel quality. The candidate will be also responsible for setting up realistic experimentation scenarios using Eurecom OpenAirInterface.org platform as well as for performance evaluation and validation of such scenarios. The work will be carried out in the framework of the European project CONECT. The CONECT consortium comprises strong industrial partners like Samsung and Thales as well as high class universities such as Berkeley, EPFL, and CERTH. It is funded by the European Commission under the 7th Framework Programme. The project has a strong experimental aspect and will make heavy use of Eurecom's OpenAirInterface platforms. The OpenAirInterface is an open-source software defined radio (SDR) development platform targeting innovations in the next generation wireless systems (LTE/LTE-A) and networking experimentations. The platform uses all-IP wireless networking and implements the PHY and MAC layer completely in software. The platform environment implements both real-time and non real-time protocol stacks and is based on RTAI/Linux or ECOS open-source developments.
