ABSTRACT
In this paper we present a graph-based resource allocation scheme for sidelink broadcast V2V communications. Harnessing available information on geographical position of vehicles and spectrum resources utilization, eNodeBs are capable of allotting the same set of sidelink resources to different vehicles distributed among several communications clusters. Within a communications cluster, it is crucial to prevent time-domain allocation conflicts since vehicles cannot transmit and receive simultaneously, i.e., they must transmit in orthogonal time resources. In this research, we present a solution based on a bipartite graph, where vehicles and spectrum resources are represented by vertices whereas the edges represent the achievable rate in each resource based on the SINR that each vehicle perceives. The aforementioned time orthogonality constraint can be approached by aggregating conflicting vertices into macro-vertices which, in addition, reduces the search complexity. We show mathematically and through simulations that the proposed approach yields an optimal solution. In addition, we provide simulations showing that the proposed method outperforms other competing approaches, specially in scenarios with high vehicular density.

Hierarchical Subchannel Allocation for Mode-3 Vehicle-to-Vehicle Sidelink Communications
SenSys '17: Proceedings of the 15th ACM Conference on Embedded Network Sensor SystemsIn this poster we present a graph-based hierarchical subchannel allocation scheme for V2V sidelink communications in Mode-3. Under this scheme, the eNodeB allocates subchannels for in-coverage vehicles. Then, vehicles will broadcast directly without the ...
Fairness Guaranteed Cooperative Resource Allocation in Femtocell Networks
User-deployed low-power femtocell access points (FAPs) can provide better indoor coverage and higher data rates than conventional cellular networks. However, a major problem in this uncoordinated frequency reuse scenario is the inter-cell interference. ...
Cooperative resource allocation scheme for mitigating interference to victim macro UEs in LTE-femtocell networks
ICUIMC '13: Proceedings of the 7th International Conference on Ubiquitous Information Management and CommunicationDue to the rapid growth of demands for high data rate service in indoor wireless communications, most of the cellular operators are recently interested in femtocell. Femtocell is low power and low cost indoor base station to cover traffics occurred ...
