SmartDR:A device-to-device communication for post-disaster recovery

When UAV and ad-hoc NOMA-BS meets in Disaster: A scheduling and mode selection approach

“…where 𝑃 𝑢 represents transmit power of UAV, 𝑑 𝑢 is the distance between the UAV and ground users, 𝑚 is the path-loss exponent, and 𝜂 denotes the attenuation factor. The LoS probability can be expressed in [9]:…”

“…Currently, D2D communication can be a good solution for disaster management. In [9], authors have studied the disaster recovery operation using D2D communication utilizing smartphones. Smart disaster recovery includes multi-channel hopping and energy awareness on the demand distance vector of the network.…”

D2D Multi-hop Multi-path Communications in B5G Networks: A Survey on Models, Techniques, and Applications

“…The E2E delay can be derived from the processing delay per hop, the average waiting delay per hop, and the number of hops [3,46]; the per-hop parameters of coding delay, propagation delay, and transmission delay [47]; or simply transmission delay [60,62]. In some delay models, the E2E delay further includes the MHMP control process [48,50,51,58].…”

“…Further reactive caching techniques that are more efficient are required to study in the context of D2D MHMP communications. It means that 6 EAI Endorsed Transactions on Industrial Networks and Intelligent Systems 10 2020 -01 2021 | Volume 7 | Issue 25 | e3 D2D Multi-hop Multi-path Communications in B5G Networks: A Survey on Models, Techniques, and Applications 22,33,34,36,37,40,44,63,64,66,75,86] [ 26,27,51,53,54,60,61,79,82,85,[87][88][89][90][91][92] [ [41][42][43]53] the contents are placed in the best SUs in advance, with a certain caching density based on a prediction model of content popularity. And then, whenever a DU requests the content, D2D MHMP D2D communications are immediately established to serve the DU.…”

“…The requirement to keep the communications ongoing is a critical matter attracting researches. Due to the damage of mobile networks during disasters, under limited energy and battery life of the mobile nodes, D2D MHMP communications are equipped with some special techniques, such as clustering, energy harvesting, cooperative beamforming [22,27,33,51,54,63,66,75,88]. Besides conventionally using the remaining mobile nodes of network infrastructure, UAVs are also deployed to establish D2D MHMP information exchanged for disaster management [53,85,89,91].…”
